Summary: The inflammatory response to a truly closed castration procedure in 51 horses using an inguinal approach was quantified by serum amyloid A (SAA) measurements to be on average 94 mg/L on day three after surgery. The average SAA value after field castrations, using a scrotal approach, was reported by four different investigations to be between 480 and 708 mg/L on day three post‐operatively. The discrepancy in SAA levels between these different approaches proved to be significant (p < 0.001), quantifying a substantially lower inflammatory response of the closed inguinal technique over regular field castrations using a scrotal approach.

Beefalo is a fertile hybrid descendant of domestic cattle (Bos taurus) and American buffalo (Bison bison). Crossbred (¾Beefalo¼Nellore) beef cattle raised and finished in a feedlot or on pasture were evaluated for the effect of two ages (8 and 13 months) at castration on nutrient intake, performance, and carcass characteristics. In the feedlot, they received a total diet with a roughage:concentrate ratio of 55:45, and those kept on Brachiaria decumbens pastures were supplemented at 0.8% of body weight (BW) with the same concentrate based on corn and soybean meal (17.8% CP and 73% TDN). Thirty-six crossbred (¾ Beefalo ¼ Nellore) beef cattle with 209.2 ± 14.6 kg BW were used, which at weaning, at 8 months of age, were randomly divided into two groups, one of them destined to the feedlot system and the other group to the supplementation system on pasture. In each system (feedlot and pasture) the following treatments were distributed: castration at 8 months (at weaning, C8), castration at 13 months (C13), and non-castrated (NC), with six animals per treatment by system. All animals were slaughtered at 18 months of age. There was no significant interaction between the systems and castration ages for all variables studied. The averages of slaughter weight of feedlot animals were 475.6; 494.3 and 510.7 kg; and finished in pasture were 424.3; 428.0 and 418.7 kg for C8, C13, and NC treatments, respectively. The average subcutaneous fat thickness of the feedlot steers were 4.5, 3.5, and 1.3 mm, and for pasture-finished steers were 2.4, 1.6, and 1.8 mm for C8, C13, and NC treatments, respectively. Non-castrated animals have greater performance and carcass characteristics than castrated animals independent of the finished system. Animals non-castrated finished on Brachiaria grass pastures and slaughtered at 18 months of age require more intensive feeding management or even greater age at slaughter to obtain an ideal carcass finishing despite castration.

Background: Castration is the most common surgical procedure in domesticated equids; surgical techniques used and perioperative management vary considerably. Objectives: To identify and chart the current evidence on perioperative complications associated with different methods of surgical castration in domesticated equids. Study design: Joanna Briggs Institute systematic scoping review. Method: CAB Abstracts, Medline and Embase databases were searched using terms related to equine castration complications. Two authors independently and blindly screened publications against eligibility criteria. Data on study methods, perioperative management, surgical techniques, and perioperative complications were extracted. Surgical techniques were grouped into categories depending on technique; open, closed or half‐closed, and whether the parietal tunic was open or closed at the end of surgery. Results: The search identified 1871 publications; 71 studies met the final inclusion criteria. The data reported 76 734 castrations, most of which were open or closed, with the vaginal tunic remaining open at the end of surgery. Twenty‐five studies reported information regarding surgical techniques and perioperative management, allowing detailed charting and comparisons, of which analgesia and antimicrobial usage varied notably. Eighteen different complications were reported, with swelling or oedema being the most common. Evisceration was most commonly reported in draught breeds and Standardbreds, and the risk appeared low if the parietal tunic was closed at the end of surgery. Main limitations: Grey literature and studies not available in English were not included. Existing studies varied greatly in perioperative management, surgical techniques and reporting of outcomes, making evidence consolidation problematic. Conclusion: A lack of consensus regarding complication definitions creates uncertainty and discrepancies between complication rates associated with different surgical techniques and perioperative management. The implementation of standardised systems for describing surgical techniques and complications is recommended for future studies. A number of studies did not follow current recommendations for perioperative analgesia and use of antimicrobials. [ABSTRACT FROM AUTHOR]

Grimace scales have been used to assess pain in various animal species. This study aimed to develop the calf grimace scale (CGS), evaluate its responsiveness and the effect of external factors (change of environment and dam separation, and restraint) on CGS. Sixty-nine Angus calves, 6–8 weeks old, were randomly allocated into castrated (n = 34) and sham castrated (n = 35) groups. Images were extracted from videos pre- (M1-M4), during- (M5), and post-castration/sham castration (M6, M7). Six facial action units (FAUs) were identified: ear position, orbital tightening, tension above the eye, nostril dilation, straining of chewing muscle, and mouth opening. Final CGS median scores increased after castration (P < 0.001) for both non-restrained (M7 versus M2) and restrained (M6 versus M3) calves, indicating scale responsiveness. Final CGS median scores increased (P < 0.001) when calves were subjected to external factors before castration (M1 [baseline] versus M2 and M3). However, there was no difference (P > 0.05) in CGS median scores before and after sham castration, regardless of restraint (M3 versus M6, and M2 versus M7), indicating that the external factors may have reached a maximum effect. The CGS is composed of six FAUs, responsive to acute pain and can identify stress unrelated to pain. [ABSTRACT FROM AUTHOR]

Telocytes are CD34+ interstitial cells that have long cytoplasmic projections (called telopodes), and have been detected in several organs, including those of the male reproductive system. In this brief review we evaluate the role of telocytes in tissue organization of the different organs of the male reproductive system in which these cells were studied. In general terms, telocytes act in the tissue organization through networks of telopodes that separate the epithelia from the stroma, as well as dividing the stroma into different compartments. In addition to this contribution to the structural integrity, there is direct and indirect evidence that such "walls" formed by telocytes also compartmentalize paracrine factors that they or other cells produce, which have a direct impact on morphogenesis and the maintenance of organ cell differentiation, as well as on their normal physiology. Moreover, alterations in telocytes and telopode networks are correlated with pathological conditions in the male reproductive system, in response to profound changes in structural organization of the organs, in inflammation, hyperplasia and cancer. Further studies are necessary to evaluate the molecular pathways telocytes employ in different contexts of physiology and disease. [ABSTRACT FROM AUTHOR]

Background: Biological aging is a complex process influenced by various factors, including reproductive status and castration. This study aimed to evaluate the impact of castration on biological aging in dogs. Method: Fifteen male crossbred dogs were randomly divided into a sham-operation control group (n = 5) and a castrated group (n = 10). Blood samples were collected at weeks 0, 4, 8, 12, 16, and 18 post-surgery. Malondialdehyde (MDA as indicator of Lipid peroxidation), C-reactive protein (as an indicator of inflammation), telomere length, mitochondrial DNA (mtDNA) copy number, and the expression of age-related (P16, P21, TBX2) and telomerase-related (TERT) genes were assessed in blood samples. Results: Plasma MDA levels were higher in the control group at weeks 16 and 18, while CRP levels were higher only at week 18. Telomere length and mtDNA copy number were lower in the control group at week 18. Gene expression analysis showed that P16 was lower in the control group at weeks 8 and 12, P21 and TERT were lower at weeks 16 and 18, and TBX2 was lower at weeks 16 and 18. The TBX2/P16 ratio was lower in the control group at weeks 16 and 18 but higher at week 12, while the TBX2/P21 ratio did not differ between groups. Conclusion: Castration appears to have a protective effect against biological aging in dogs, as evidenced by lower lipid peroxidation, inflammation, and age-related changes in telomere length, mtDNA copy number, and gene expression.

Introduction: Stallion castration is a standard procedure with a risk of post-surgical complications. Castration induces an acute phase response (APR). Serum Amyloid-A (SAA) is a well-studied major acute phase protein (APP), that has been shown to be a good marker for the development of post-surgical complications. The current gold standard for reducing the APR after castration is Flunixin-Meglumin, which is a nonsteroidal anti-inflammatory drug (NSAID) inhibiting COX1/2. In contrast, Traumeel LT ad us. vet. can modulate the APR by induction of the inflammation resolution. The aim of this study was to compare the effect of Flunixin-Meglumin and Traumeel LT ad us. vet. on the acute phase response. Material and methods: A total of 60 stallions were recruited and 54 stallions entered the study with 27 stallions in each treatment group. The stallions were treated pre- and postoperatively with either Flunixin-Meglumin (FL) or with Traumeel LT ad us. vet. (TR). Blood was taken before and 24 h, 48 h and 72 h after castration. The following main parameters were assessed: SAA, fibrinogen, iron, white blood cells, neutrophils, Interleukin1ß, and cortisol. Wound healing and pain were assessed at 8 time points. Results: The main variable SAA was increased after surgery reaching a mean value of 122 µg/ml in the FL group and a mean SAA of 226 µg/ml in the TR group 48 h after surgery, reaching a significant difference only at the 24 h timepoint (p = 0.03). All stallions had the highest pain summary score 8 hours after surgery, with decreasing values thereafter. The pain scores were not statistically different at any time point. In the FL group five stallions developed a suture dehiscence compared to only one stallion in the TR group (p = 0.001). Discussion: Within the limitations of this study, Traumeel LT ad us. vet. seems to have proresolving effects on the inflammation induced by surgery making it a valuable treatment to reduce the APR induced by castration. Due to its different mode of action, Traumeel LT ad us. vet. might be an alternative treatment option if gastrointestinal side effects or renal side effects of NSAIDs should be avoided. Further studies are needed combining Traumeel LT ad us. vet. and Flunixin. [ABSTRACT FROM AUTHOR]

In Kosilek v. Spencer the U.S. Court of Appeals for the First Circuit adopted The World Professional Association of Transgender Health Standards of Care (WPATH SOC) as medical consensus on gender affirming care and held that Michelle Kosilek could access gender affirming care but that she did not meet the criteria for gender affirming surgery. In Gibson v. Collier the U.S. Court of Appeals for the Fifth Circuit with a sparse record and no expert testimony denied Vanessa Lynn Gibson access to gender affirming surgery and incorrectly claimed that Kosilek did not support the WPATH SOC as representing the medical consensus on gender affirming care. Finally, the U.S. Court of Appeals for the Ninth Circuit held in Edmo v. Corizon that denying access to gender affirming surgery to an incarcerated transgender person suffering from severe gender dysphoria resulting in two attempts at self-castration, cutting to reduce genital distress, and suicidal ideation violated the Eighth Amendment. In doing so, the Ninth Circuit joined medical and scientific organizations who widely adopt The World Professional Association of Transgender Health Standards of Care (WPATH SOC) as medical consensus on gender affirming care. Nonetheless, 10 Ninth Circuit Judges dissented to the denial of rehearing en banc in Edmo. Although the Supreme Court denied certiorari (with Justice Thomas and Alito dissenting), the Supreme Court also denied certiorari in the Fifth Circuit case Gibson v. Collier which denied access to gender affirming surgery and rejected the WPATH SOC without offering any alternatives. [ABSTRACT FROM AUTHOR]

Simple Summary: Neutering, which includes orchiectomy for males and ovariohysterectomy for females, is a common practice in dogs to control populations and prevent health issues. Despite its benefits, neutering can lead to hormonal changes that may contribute to a tendency toward obesity over time. Our study investigated how neutering in both female and male dogs affects hormones involved in metabolism and appetite regulation, specifically nesfatin-1, serotonin, dopamine, TSH, and T4. We observed that neutering decreased levels of nesfatin-1, serotonin, and T4, and increased TSH levels in both genders. These hormonal changes could be part of a mechanism contributing to the higher risk of obesity observed in neutered dogs in the long term. Neutering of dogs, whether male or female, provides various benefits such as contraception, population control, and the prevention of reproductive disorders and undesirable sexual behaviors. However, it is also associated with an increased risk of obesity, which may be directly linked to post-neutering hormonal changes. Our study aims to determine the effects of neutering on plasma levels of nesfatin-1, serotonin, dopamine, TSH, and T4—hormones implicated in obesity and metabolic regulation. Fourteen dogs (seven males and seven females), aged between 1 and 3 years, were included in this study. Male dogs underwent orchiectomy and females underwent ovariohysterectomy. Blood samples were collected before surgery and on days 7 and 14 post-operatively to measure the plasma levels of these hormones using ELISA. The results showed a significant decrease in nesfatin-1, serotonin, and T4 levels, along with a significant increase in TSH levels in both male and female dogs post-neutering. While these hormonal changes are likely part of the body's adaptive response to neutering, they may represent a potential mechanism that contributes to the long-term tendency toward obesity in neutered dogs.

OBJECTIVE To investigate the effect of intranasal (IN) flunixin meglumine (FM) and intra-inguinal (IG) lidocaine on castration inflammation using prostaglandin E2 (PGE2) concentration as a biomarker. METHODS This randomized controlled trial was conducted in March 2022. Blood was collected at -24, 1, and 24 hours postcastration for PGE2 quantification from 195 piglets that received 1 of 8 treatments: (1) saline (1.5 mL) applied IG and IN (0.2 mL) followed by surgical castration (n = 24); (2) saline (1.5 mL) IG and IN (0.2 mL) followed by sham castration (25); (3) lidocaine (20 mg/kg or 1.5 mL) IG followed by surgical castration (24); (4) lidocaine (20 mg/ kg or 1.5 mL) IG followed by sham castration (25); (5) FM (2.2 mg/kg) IN followed by surgical castration (25); (6) FM (2.2 mg/kg) IN followed by sham castration (24); (7) lidocaine (20 mg/kg or 1.5 mL) IG and FM (2.2 mg/kg) IN followed by surgical castration (24); and (8) lidocaine (20 mg/kg or 1.5 mL) IG and FM (2.2 mg/kg) IN followed by sham castration (24). RESULTS Prostaglandin E2 concentrations did not increase following the castration procedure and were not an effective biomarker of castration inflammation. Piglets that received lidocaine demonstrated no difference in PGE2 levels across all time points. Piglets administered FM had lower PGE2 concentrations at 1 hour and 20 minutes postdrug administration in both the sham and castrated piglets. CONCLUSIONS Prostaglandin E2 was not an effective biomarker to quantify castration inflammation. Flunixin meglumine was able to reduce PGE2 concentration in piglets regardless of castration procedure, but lidocaine had no impact. Decreased PGE2 levels in FM-treated pigs are likely associated with the drug's ability to mitigate a noncastration-associated inflammatory process occurring independent of the castration procedure. CLINICAL RELEVANCE Flunixin meglumine reduced circulating PGE2 concentration in the blood, regardless of the castration procedure, indicating a potential for the drug to mitigate an inflammatory process unrelated to castration.

Gender‐affirming care is treatment that recognizes and affirms the gender identity of transgender and gender‐diverse (TGD) individuals. Though not all TGD people choose to surgically transition, gender‐affirming surgeries (GAS) are an important part of many TGD people's transition. GAS can include a wide array of procedures aimed at aligning an individual's physical characteristics and gender identity. This review describes the most common procedures considered to be GAS, detailing important relevant considerations for each procedure. These include transfeminine procedures (i.e., breast augmentation, penile inversion vaginoplasty, orchiectomy, tracheal shave, and facial feminization); transmasculine procedures (i.e., chest masculinization, hysterectomy, phalloplasty, and metoidioplasty); and other procedures (i.e., fertility preservation and hair removal). Patient outcomes and the legal landscape for GAS are also discussed to contextualize these procedures within largest discourses surrounding gender‐affirming care. [ABSTRACT FROM AUTHOR]

INTRODUCTION: We aimed to investigate the surgical outcomes following inguinal and subinguinal urologic procedures under deep intravenous sedation (DIVS) with multimodal local anesthesia (LA). METHODS: We conducted a retrospective cohort study from September 2022 to December 2023 including adult patients deemed eligible for day surgery (American Society of Anesthesiologist score 1-3) undergoing radical orchiectomy (RO), microscopic varico- score 1-3) undergoing radical orchiectomy (RO), microscopic varico-celectomy (MV), or microscopic denervation of the spermatic cord (MDSC). All procedures were performed at a single urologic ambulatory surgical center and outpatient clinic, and by a single surgeon (PP). Procedures were performed through a subinguinal or inguinal approach with DIVS and adjunctive multimodal LA. We evaluated intraoperative complications and relevant surgical outcomes and parameters. RESULTS: A total of 103 patients were included in the analysis with a mean age ± standard deviation of 37.3±9.6. This included 25 patients who underwent RO, 54 patients who underwent MV, and 24 patients who underwent MDSC. All procedures were completed successfully without intraoperative complications. Oncologic outcomes were preserved, fertility outcomes improved, and pain scores reduced similarly to the expected rates in the literature. CONCLUSIONS: Our preliminary results demonstrate the safety, effectiveness, and feasibility of performing inguinal and subinguinal urologic procedures under DIVS with LA. These findings suggest that this technique preserves high-quality care while avoiding the unnecessary risks of general or spinal anesthesia, representing an opportunity to transfer these cases outside of hospitals' operating rooms into outpatient ambulatory centers.

Endometriosis typically presents in postmenarchal patients with cyclic and acyclic pelvic pain. However, there are reports of endometriosis in premenarchal patients. We report a 10-year-old individual with 46,XY difference of sex development who was found to have endometriosis at the time of laparoscopic gonadectomy for gonadoblastoma. Although rare, endometriosis can occur in 46,XY individuals prior to puberty, highlighting the complex origin of the disease. [ABSTRACT FROM AUTHOR]

The article analyzes the relationship between exile and identity in Uruguayan poet Cristina Peri Rossi. Her poetry collection "Estado de exilio" is examined, and four moments in her journey are identified: pain, castration, integration, and love. Psychoanalysis is used to interpret these stages, highlighting how exile breaks the rigid structures of the subject. The importance of language and writing as ways to overcome the pain of exile is mentioned. The article concludes by emphasizing the possibility of reinventing identity through exile.

Testicular ischemia requires timely diagnosis and definitive management to avoid serious consequences such as orchiectomy. It is almost always caused by testicular torsion; however, there are other causes to be aware of. A 32-year-old man developed testicular ischemia following a laparoscopic robotic-assisted inguinal hernia repair with preperitoneal mesh. The ischemia progressed to a fully infarcted testicle with no evidence of torsion on subsequent surgical exploration. He ultimately did require an orchiectomy. While extremely rare, testicular ischemia or infarct must be considered in patients presenting with testicular pain shortly after inguinal hernia repair. Emergent surgical evaluation and loosening of the hernia mesh may be required to salvage the testicle. [ABSTRACT FROM AUTHOR]

Abstract Background Biological aging is a complex process influenced by various factors, including reproductive status and castration. This study aimed to evaluate the impact of castration on biological aging in dogs. Method Fifteen male crossbred dogs were randomly divided into a sham-operation control group (n = 5) and a castrated group (n = 10). Blood samples were collected at weeks 0, 4, 8, 12, 16, and 18 post-surgery. Malondialdehyde (MDA as indicator of Lipid peroxidation), C-reactive protein (as an indicator of inflammation), telomere length, mitochondrial DNA (mtDNA) copy number, and the expression of age-related (P16, P21, TBX2) and telomerase-related (TERT) genes were assessed in blood samples. Results Plasma MDA levels were higher in the control group at weeks 16 and 18, while CRP levels were higher only at week 18. Telomere length and mtDNA copy number were lower in the control group at week 18. Gene expression analysis showed that P16 was lower in the control group at weeks 8 and 12, P21 and TERT were lower at weeks 16 and 18, and TBX2 was lower at weeks 16 and 18. The TBX2/P16 ratio was lower in the control group at weeks 16 and 18 but higher at week 12, while the TBX2/P21 ratio did not differ between groups. Conclusion Castration appears to have a protective effect against biological aging in dogs, as evidenced by lower lipid peroxidation, inflammation, and age-related changes in telomere length, mtDNA copy number, and gene expression.

Surgical castration is a primary method for controlling male fertility, but it is impractical for large-scale population control of stray animals. Developing nanoparticle-mediated sterilants that induce cell apoptosis rather than necrosis is a complex and promising area of research. This study aimed to investigate the impact of intratesticular administration of alpha-mangostin encapsulated in nanostructured lipid carriers (AM-NLC) on testicular changes and any associated adverse effects over a 168-day observation period. Thirty-two healthy mature tomcats were enrolled. None of the cats treated with either AM-NLC (n = 28) or blank NLC (n = 4) exhibited noticeable complications related to pain or stress throughout the study, as assessed by clinical examination, blood profiles, and serum amyloid A levels. Histopathological analysis of AM-NLC treated cats revealed seminiferous epithelium degeneration, leading to defective tubules. Key findings included germ cell depletion, disorganized spermatogenic cells without spermatids in certain areas, apoptotic bodies, and intracytoplasmic vacuolization. The intertubular compartment showed no signs of inflammation, hyalinization, fibrosis, or necrosis. Despite widespread degeneration, some normal tubules were present in focal areas. The severity score of seminiferous tubule degeneration significantly increased from day 56 onwards (P < 0.05), suggesting a gradual and progressive compromise of the seminiferous epithelium. In contrast, testes from the blank-NLC group exhibited normal spermatogenesis. Overall, there were no significant changes in the volume of dissected testes, serum testosterone levels, or apoptotic index in AM-NLC-treated cats (P > 0.05). In conclusion, this study represents the first in vivo investigation of apoptotic-inducing agents as a novel nanomedicine-based antifertility compound for non-surgical castration in male animals. While the AM-NLC formulation proved safe for intratesticular administration, it failed to induce infertility in cats, as epididymal spermatozoa persisted throughout the study. Further research into alternative apoptosis-inducing nanomedicine sterilants remains both essential and challenging. [ABSTRACT FROM AUTHOR]

Although Italian castrati did not feature prominently in the French Enlightenment, they nonetheless became a subject of scientific discussion in the kingdom insofar as they embodied a Western eunuchism. Used to explore the ethical limits of surgical procedures, musical castration was included in a number of treatises, both developed and more anecdotal, and raised a host of questions relating to bodily norms, gender identity, reproductive capacity and sexuality. This article sets out to investigate the way in which the physical and moral portrayal of castrati developed by French physicians and naturalists during the Enlightenment was part of the effort to construct and medically define sex, with a particular focus on setting standards for the masculine. In the second half of the 18th century in particular, the figure of the castrato served as a means of setting out the physical and moral characteristics of a hegemonic masculinity 'à la Française' and, consequently, the contours of a subordinate masculinity (Italian, southern, oriental) of which the singers would be the embodiment.

The failure to prevent Hamas’s slaughter of some 1,300 Israelis on 7 October 2023 – the largest massacre of Jews since the Holocaust – is a direct result of an emergency phone consultation three hours before the terror group’s invasion of Israel with the participation of the IDF’s and Shin Bet’s top leaders, who decided to do nothing despite acute warning signals and failed to alert the Gaza division commander and the political echelon to the imminent attack. Had they taken the minimal precautionary measures, the catastrophe would have been averted altogether. To fully understand the mindset underlying this monumental blunder requires tracing its evolution within the context of the 30-years-long Oslo peace delusion in general, and during the turbulent year preceding the 10/7 massacres in particular. That is: the substitution of a grand strategic deception aimed at Israel’s destruction for a true peace process and the attendant emasculation of the IDF’s military capabilities and combative/offensive ethos, on the one hand, and the unravelling of Israel’s sociopolitical fabric that culminated in the 2023 mass civil disobedience that enticed Hamas into action, on the other. Even Israeli Prime Minister Benjamin Netanyahu, who opposed the Oslo process from the outset and managed to neutralise its most catastrophic potential calamity – the establishment of a Palestinian state committed to Israel’s destruction in the West Bank and Gaza – failed to extricate Israel from this disastrous course and was ironically forced to bear its full brunt on 7 October 2023.

Although replacement of fat with fiber is a good strategy to avoid boar taint on high‐fat content products, as sausages, the final purchase intention is related to other external factors such as welfare and healthiness. So, the aim of this study was to evaluate the consumers' perception of sausages with fat replaced by fiber, elaborated with meat from non‐castrated male pigs, and to determine the influence of the consumers' habits and demographic parameters on their beliefs related to pig castration. An online survey was carried out. A total of 131 consumers answered a questionnaire about habits and beliefs related to meat and meat product issues. Subsequently, they evaluated four images of labeled products (castrated–not castrated/normal–reduced‐fat/traditional–high fiber content) with the Check‐all‐that‐apply (CATA) test. In all, 87.7% of meat consumers perceived meat products as positive, although 71% trimmed the fat previous consumption. In a 9‐point agreement scale, "Animal welfare worries me" obtained 7.5 and "the castration without anaesthesia should not be performed" 7.4. There was a higher grade of agreement with "castration of pigs justification to improve smell a flavour" in primary education level and in rural residence (p <.05). Sausages from castrated animals were perceived as fatty, juicy, appetizing, and animal cruelty. Reduced‐fat and rich/high fiber sausages were not associated with "healthy" but with "expensive" and "unpleasant." Although reduced‐fat entire male pork sausages with vegetable fiber could be a better option for marketing uncastrated male pork, they will need more than fiber claims to be associated with healthy products and the consumer should be previously informed if he could appreciate the meaning of castration labeling.

In 1854, prior to the American Civil War, Gideon Lincecum (1793–1874), an enslaver and physician from Texas, proposed a law advocating for the castration of criminals to prevent additional crimes committed by men, especially Black men, and to inhibit hereditary immorality. Shockingly, Lincecum also viewed his law as a “solution” to the “immorality” of abolitionists who supported freedom for enslaved African Americans. Lincecum inspired physicians and scientists promoting eugenics in the twentieth century who racially targeted Black men as candidates for castration. Lincecum’s castration law magnifies the ugliness of scientific racism and violent perceptions of justice as deriving from the same ideological white supremacy that persisted from before the Civil War into the twentieth century.

Background: Androgen deprivation therapy, themainstay of treatment for patients with advanced prostate cancer, can be either medical or surgical. Surgery has cost beneits compared to medical treatment. In this study, we evaluated the use of simple and epididymal-sparing orchiectomy in 2 diferent practice settings for the treatment of metastatic prostate cancer. Methods: We reviewed patients who underwent surgical castration for metastatic prostate cancer between 2011 and 2022. The primary outcome was achieving castration-level total testosterone of<50 ng/dL.We also compared the characteristics of patients who were seen at a public academic teaching hospital vs those who were seen at a private community hospital (oncology group practice), andwe evaluated the impact of orchiectomy approach (simple vs epididymal-sparing orchiectomy) on patient outcomes. Results:We analyzed 101 patients who underwent orchiectomy: 40 (39.6%) at a public academic teaching hospital and 61 (60.4%) at a private community hospital (oncology group practice). Of these patients, 81 (80.2%) underwent simple orchiectomy and 20 (19.8%) underwent epididymal-sparing orchiectomy. Forty-nine patients (48.5%) had previously receivedmedical androgen deprivation therapy, 9 (18.4%) of whom had medication adherence issues. Patient age, race, and marital status difered signiicantly between hospital facilities. The overall surgical complication rate was 3.0%. Postoperative total testosterone levels were available for 81 patients, drawn amedian of 57 days after surgery [IQR 30, 123]. All patients had castrate-level total testosterone (median 10 ng/dL [IQR 9, 19]) postoperatively, with no diferences seen between surgery location (P = 0.84) or surgical technique (P = 0.90). Conclusion: Simple or epididymal-sparing orchiectomy is safe and efective for surgical castration and is an alternative tomedical androgen deprivation therapy for patients diagnosed with metastatic prostate cancer regardless of the practice demographics.

Objective Transgender women who underwent gonadectomy have lower serum testosterone concentrations than cisgender women. There is uncertainty regarding the dosing and side effects of supplementation of testosterone in transgender women. This study aimed to assess the feasibility of dosing testosterone to the cisgender female physiological range in transgender women. In addition, we explored changes in cardiovascular parameters, virilizing side effects, and clinical symptoms. Design This is an open-label, single-arm feasibility study. Participants initially went through a dose-titration phase with 2-week intervals of 0.07-0.09-0.13 mL (277-318-403 μg bioavailable testosterone) testosterone 2% gel to establish a dose leading to serum testosterone concentrations between 1.5 and 2.5 nmol/L. This dose was then continued for 8 weeks. Methods Participants applied daily transdermal testosterone 2% gel (Tostran®) at the prescribed dosage. Testosterone was measured every 2-4 weeks. Laboratory analyses, side effects, and clinical symptoms were evaluated. Results In total, 12 participants were included. Most participants required a dose of 0.07 mL (277 μg bioavailable testosterone) or 0.09 mL (318 μg bioavailable testosterone) to reach serum testosterone concentrations of 1.5-2.5 nmol/L. Continuing this dose, testosterone concentrations remained stable throughout the study. Changes in clinical outcomes were in the desired direction, and side effects were mild. Conclusions The use of testosterone supplementation in transgender women seems feasible and safe in the short term. Although dosing requires personalized titration, stable testosterone levels can be established. A blinded, placebo-controlled, randomized clinical trial is needed to study the clinical benefit.

Simple Summary: Donkey welfare and pain relief are of particular importance in the veterinary field. Therefore, pain management during surgical operations in field settings is mandatory. The current study sheds light on the antinociceptive effect of a combination of dexmedetomidine and nalbuphine premedication prior to total intravenous anesthesia using ketamine-propofol in castration procedures in field conditions. Shortly after castration, the proposed combination of dexmedetomidine and nalbuphine resulted in decreased postoperative pain. In addition, the cardiac function was improved compared to using dexmedetomidine alone during anesthesia. This was demonstrated using established clinicophysiological assessments, serum biochemical markers, and behavioral pain scores for six hours post-recovery. Dexmedetomidine and nalbuphine premedication prior to total intravenous anesthesia using ketamine-propofol showed potential benefits compared to dexmedetomidine alone in providing more analgesia and managing postoperative pain in jacks undergoing castration under field conditions. This study evaluated the antinociceptive effect of dexmedetomidine-nalbuphine vs. dexmedetomidine alone in jacks undergoing field castration under total intravenous anesthesia. Jacks were premedicated with intravenous (IV) dexmedetomidine (5 µg/kg), either alone (Group D, n = 6) or in combination with 0.3 mg/kg nalbuphine (Group DN, n = 6). IV ketamine (1.5 mg/kg) and propofol (0.5 mg/kg) were used to induce general anesthesia, which was maintained by a continuous propofol (0.2 mg/kg/min) IV infusion. The quality of anesthesia, analgesia, and recovery were evaluated. A simple descriptive scale (SDS) was used to measure pain from the recovery time to 6 h later. The DN group exhibited improvements in analgesic and recovery quality and SDS of pain at 1-, 2-, and 3-h post-recovery. There was an apparent improvement in cardiac status, as evidenced by the enhanced heart rate and electrocardiogram findings compared to group D during surgery and recovery time. The DN group had a lower level of inflammatory cytokines, both during the surgery and shortly after recovery. Therefore, the dexmedetomidine-nalbuphine combination prior to IV anesthesia of ketamine and propofol in jacks undergoing field castration resulted in a stable surgical plane of anesthesia, improved antinociception, less pain postoperatively, and better cardiac stability.

Testicular sex cord-stromal tumors are clonal neoplasms, with the majority being of Leydig cell followed by Sertoli cell origins. In Leydig cell tumors, adipocytic differentiation has been previously reported as a possible distinguishing feature, which has not been reported in other sex cord-stromal tumors. Herein, we report a case of a 48-year-old man who presented with an incidentally discovered 1.1 cm testicular mass, for which he underwent partial orchiectomy. Microscopically, the tumor showed features consistent with sex cord-stromal tumor with strong and diffuse nuclear and cytoplasmic reaction for B-catenin immunohistochemistry, supporting the diagnosis of Sertoli cell tumor. A novel adipocytic differentiation, reported previously in Leydig cell tumors, was present in this tumor. [ABSTRACT FROM AUTHOR]

Mixed gonadal dysgenesis (MGD) is a disorder of sex development caused by mosaicism of the Y chromosome, represented by 45,X/46,XY. Prophylactic gonadectomy is recommended as soon as possible after its diagnosis, owing to a high risk of malignancy. In the present case, a 21-year-old woman presented with primary amenorrhea. Although the patient's external genitalia were female, the patient exhibited a hypoplastic uterus, wherein the ovaries were difficult to identify. The patient's height was 146 cm; they had cubitus valgus and webbing of the neck, leading to the consideration of a disorder of sex development. Chromosomal examination revealed 45,X/46,XY mosaicism. Thus, the patient was diagnosed with MGD. After thorough counseling, laparoscopic bilateral gonadectomy was performed. Pathological examination revealed a gonadoblastoma of the left gonad. Postoperatively, the patient had no recurrence and continued on Kaufmann therapy. In conclusion, prophylactic gonadectomy is recommended immediately following a diagnosis of MGD; however, the timing of the surgery should be carefully considered and adequate counseling should be conducted by a multidisciplinary team.

BACKGROUND: This study aimed to evaluate the approaches of pediatric surgeons and pediatric urologists in Türkiye regarding the diagnosis and treatment of testicular torsion (TT) and their adherence to the European Association of Urology (EAU) pediatric urology guideline. METHODS: A survey consisting of 19 questions, accompanied by an annotation describing the objective of the study, was emailed to pediatric surgeons and pediatric urologists in June and July 2023. RESULTS: Of the 95 respondents, 62.1% had over 10 years of experience, and 48.4% treated more than five cases of TT annually. Of the participants, 87.4% stated that scrotal Doppler ultrasonography (US) was always used, and 12.6% stated that US was used in cases of doubtful diagnosis. Concerning treatment, 14.7% reported performing manual detorsion, 70.5% never did, and 14.7% did so only if the operating room was unavailable soon. A total of 92.6% of participants opted for emergency surgery. Among participants who perform manual detorsion, 71.4% perform surgery within 24 hours after successful manual detorsion. Regarding fixation of the contralateral testicle, 14.7% never performed it, and 27.4% did so only when they performed an orchiectomy on the torsion testicle. CONCLUSION: While most participants follow EAU pediatric urology guidelines by performing emergency surgery, the rate of manual detorsion is low. Few participants stated that emergency surgery may not be performed after manual detorsion. While all of the participants performed fixation of the torsion testicle in accordance with the guidelines, the same adherence was not observed in the contralateral testicle. [ABSTRACT FROM AUTHOR]

A 6-month-old, phenotypic, male Nigerian dwarf goat presented after bilateral abdominal gonadectomy for persistent urinary incontinence. Physical examination revealed a caudally positioned cliteropenis with an abnormally enlarged urethral opening. Abdominal ultrasound and computed tomography revealed a fluid-filled structure dorsal to the urinary bladder. The structure was removed by caudal midline laparotomy. Communication between the structure and proximal urethra was confirmed in surgery. Unexpected separation of the structure fromthe urethra in surgery necessitated normograde catheterisation through a cystotomy to pull a catheter retrograde into the bladder. Histopathology confirmed the structure as a hypoplastic uterus. The goat regained normal urine continence following surgery. [ABSTRACT FROM AUTHOR]

Simple Summary: Neutering is one of the most common procedures for dogs worldwide. While motivations for neutering vary, this procedure is often chosen with the hope of addressing undesirable behaviours in male dogs. In our study, 230 mixed-breed dogs (115 neutered and 115 intact) were examined. The dogs were categorised as "small", "medium", "large", and "giant". An online questionnaire was used, which asked about certain behavioural characteristics on the one hand and personality on the other. The results showed that neutered dogs appeared more stressed and aggressive than intact dogs. In addition, neutered small, medium, and large dogs were more stressed than giant dogs. Neutered dogs were also less social, trainable, emotionally calm and extroverted than intact dogs. This all suggests that neutering should be questioned and decided on an individual basis, as hormonal changes can have a considerable influence on dog behaviour. This study investigates the behavioural differences between neutered and intact dogs. A total of 230 questionnaires of neutered (n = 115) and intact (n = 115) mixed-breed male dogs were collected. Small, medium, large, and giant dogs were analysed to investigate a possible influence of body size. The results showed neuters were significantly more stressed than intacts (multinomial logistic regression, p = 0.001). In terms of stress by influences (such as separation anxiety and anxiety at car rides), neutered small, medium, and large dogs were more stressed than giant dogs (multinomial logistic regression, p = 0.05). Neuters were also found to be more aggressive in general (multinomial logistic regression, p = 0.04) and more aggressive on the walk (multinomial logistic regression, p = 0.02). In addition, personality questionnaires revealed significant differences in all characteristics. Neuters were less emotionally calm (multiple ordinal regression, p = 0.03), less trainable and less sociable (each multiple ordinal regression, p < 0.001). They also scored lower on extraversion (multiple ordinal regression, p = 0.04). These findings highlight the importance of further research into the behavioural effects of neutering dogs, as well as the need for evidence-based guidelines for neutering practices.

Simple Summary: Castration of male piglets without anaesthesia is facing increasing rejection in society and is also questionable for animal welfare reasons. In this study, the intranasal application of azaperone, azaperone combined with alfaxalone and azaperone combined with midazolam in various doses was tested for its suitability to ensure adequate sedation in combination with intratesticular local anaesthesia during the surgical castration of male piglets. Compared to intramuscular application, intranasal application consistently showed a poorer quality of sedation. Therefore, the intranasal application method cannot be recommended. The aim of this study was to test the intranasal administration of different anaesthetics in piglets less than seven days of age undergoing castration for their suitability for providing good-quality sedation and short induction and recovery time with minimal stress. Azaperone alone at a high (5 mg/kg), medium (3 mg/kg) and low dosage (2 mg/kg) and in two combinations with either alfaxalone or midazolam were applied intramuscularly (i.m.) or intranasally (i.n.) to 120 healthy piglets. Compared to intramuscular application, intranasal application showed longer induction times, shorter recovery times and higher scores for defence and vocalisation. In conclusion, the intranasal protocols did not meet the requirements in all groups and their use can therefore not be recommended. A rapid induction phase and good quality of sedation could not be guaranteed. [ABSTRACT FROM AUTHOR]

Mangalore melon is one of the distinct class of Cucurbitaceae family widely grown in southern part of India. Despite of having many nutritional values, there is scope for systematic hybridization study to improve the many qualitative and quantitative traits. An investigation was undertaken to develop inter-varietal hybrids and their evaluation to assess the extent of heterosis in newly developed hybrids between selected genotypes of Mangalore melon during kharif, 2019 and 2020 at College of Horticulture, Sirsi, Karnataka, India. A total of 16 intervarietal hybrids were developed by crossing 15 parental lines. Hybrids were developed using hand emasculation and hand pollination technique and the developed hybrids were evaluated using RCBD design with two replications. The results showed significant positive heterosis over mid parent and better parent for all the hybrids. The hybrids Soubhagya×RNMS-1 exhibited highest and significant heterosis over both mid parent (88.05%) and better parent (72.69%) followed by MS-19×MS-5 over mid parent (73.09%) and better parent (61.10%). From this study, it was concluded that hybrid Soubhagya×RNMS-1 was superior over their parents for most of the traits with the total yield of 8.44 kg plant-1. These best performing hybrids are need to be studied for their stability and commercial exploitation, resistance of pest and diseases, keeping quality of hybrids (storability) and experimentation on hybrid seed production technologies as well as storability of seeds should be done.

Background: The mechanism by which a state of low testosterone leads to erectile dysfunction (ED) has not been determined. Endocan is a novel marker of endothelial function. However, whether endocan is involved in the regulation of erectile function under low testosterone levels remains unclear. Aim: In this study we sought to determine whether a low-testosterone state inhibits erectile function by regulating endocan expression in the endothelial cells of the rat penile corpus cavernosum. Methods: Thirty-six male Sprague–Dawley rats aged 8 weeks were randomly assigned to 6 groups (n = 6 per group) as follows: (1) control, (2) castration, (3) castration + testosterone treatment (treated with 3 mg/kg testosterone propionate per 2 days), (4) control + transfection (4 weeks after castration, injected with lentiviral vector (1 × 108 transduction units/mL, 10 μL), (5) castration + transfection, or (6) castration + empty transfection. One week after the injection, we measured the maximal intracavernous pressure/mean arterial pressure (ICPmax/MAP), serum testosterone and nitric oxide (NO) levels, and the expression of endocan, phospho–endothelial NO synthase (p-eNOS), eNOS, phospho–protein kinase B (p-AKT), and AKT in the rat penile corpus cavernosum. Outcomes: Under a low-androgen state, the expression of endocan in the rat penile corpus cavernosum was significantly increased, which inhibited the AKT/eNOS/NO signaling pathway and resulted in ED. Results: In the castration group, the expression of endocan in the rat penile corpus cavernosum was significantly higher than that in the control group (P < .05). Additionally, the levels of p-AKT/AKT, p-eNOS/eNOS, and NO in the rat penile corpus cavernosum and ICPmax/MAP were significantly lower in the castration group than in the control group (P < .05). In the castration + transfection group compared with the castration group there was a significant decrease in the expression of endocan (P < .05) and an increase in the ratios of p-AKT/AKT, p-eNOS/eNOS, and ICPmax/MAP (P < .05) in the rat penile corpus cavernosum. Clinical implications: Downregulating the expression of endocan in the penile corpus cavernosum may be a feasible approach for treating ED caused by hypoandrogenism. Strengths and limitations: The results of this study indicte that endocan may affect NO levels and erectile function through multiple signaling pathways, but further experiments are needed to clarify the relationship between endocan and androgens. Conclusion: A low-testosterone state inhibits the AKT/eNOS/NO signaling pathway by increasing the expression of endocan in the rat penile corpus cavernosum and impairing erectile function in rats. Decreasing the expression of endocan in the penile corpus cavernosum can improve erectile function in rats with low testosterone levels. [ABSTRACT FROM AUTHOR]

Chemotherapy-induced peripheral neuropathy (CIPN) is a common and debilitating side effect of numerous anticancer agents. CIPN can persist as chronic pain or sensory symptoms for months to years after discontinuation of the anticancer agent, affecting a patient's quality of life, function, and morbidity. Although treatment recommendations are limited because of insufficient evidence, many pharmacologic and nonpharmacologic therapies are being explored to prevent and treat CIPN.

Simple Summary: Equine castration is a commonly performed veterinary surgical procedure in young colts. The procedure involves surgical removal of both testicles by transection of the spermatic cord. One complication of the procedure includes persistent hemorrhage from blood vessels within the spermatic cord and surrounding tissues. In severe cases, the hemorrhage can be life-threatening. Common treatments include packing gauze within the scrotum or attempted direct ligation of the blood vessels. Retrieval of a retracted spermatic cord is very difficult in the standing horse, and general anesthesia may be required. The risks of general anesthesia, including anesthetic recovery, could be increased in cases of hemorrhagic hypovolemia. The extensive tissue manipulation necessary for spermatic cord retrieval within the open castration site can result in further contamination. Minimally invasive techniques from abdominal approaches have been described to reduce these risks. Here, we describe a standing laparoscopic approach to cord ligation in two horses as an emergency procedure for marked hemorrhage post-castration. The feasibility and efficiency of this approach are demonstrated. Background: Persistent hemorrhage of testicular vessels is a potentially life-threatening complication of equine castration. Frequently, general anesthesia is required to retrieve and ligate the bleeding vasculature when standing wound packing and retrieval of the spermatic cord are unsuccessful. We propose standing laparoscopic ligation of the testicular arteries via the paralumbar fossa as a rapid, effective means of halting hemorrhage while avoiding castration site trauma as well as the cardiovascular and recovery risks of general anesthesia. Methods: Two geldings, 6 and 9 months old, presented for emergency treatment of severe post-castration hemorrhage of 10 and 24 h durations, respectively. Both geldings underwent standing laparoscopy under light sedation and the testicular vessels were ligated using a bipolar vessel-sealing device. Results: Testicular vessel sealing was successfully performed in both geldings by standing laparoscopy and resulted in immediate cessation of hemorrhage. In one case, a left paralumbar fossa approach allowed coagulation of both the left and right spermatic vessels. The procedure time was 25 and 35 min. No complications occurred, and both geldings recovered uneventfully. Conclusions: Standing, laparoscopic ligation of the testicular arteries is a feasible emergency treatment in young geldings and can be applied in cases of uncontrolled post-castration hemorrhage.

Summary: A 6‐week‐old male Shetland pony was presented with pollakiuria and a scrotal mass. The diagnostic procedures conducted included a thorough clinical examination, external palpation, a scrotal ultrasonographic examination and urinary catheterisation. These revealed an indirect herniation of the urinary bladder into the tunica vaginalis. Subsequently, the case was managed surgically with a partial cystectomy through an inguinal approach. Bilateral castration was performed with an additional closure of the superficial inguinal ring. Five months post‐surgery, a routine telephone questionnaire highlighted no postoperative concerns. Gross examination of the inguinal region revealed no abnormalities and the foal was maturing as expected. [ABSTRACT FROM AUTHOR]

The authors describe a case of bilateral diffuse paraneoplastic orbital myositis induced by a stage IA left testicular pure seminoma. The patient presented with findings typical of thyroid-associated orbitopathy (TAO) and was thought to have TAO until discovery of the malignancy. Treatment included an urgent orchiectomy, as well as 7 weeks of therapeutic plasma exchange. This is the fifth reported case of seminoma-associated orbitopathy, and the second to occur while cancer was in the occult phase. Although seminoma-associated orbitopathy is exceedingly rare, it can masquerade as TAO and should be considered in the differential diagnosis of any young male with atypical TAO findings.

The present study describes the morphological and immunohistochemical characteristics of a case of diffuse seminoma in a 16‐year‐old male mixed‐breed horse. According to the owner, the animal's left testicle had been gradually increasing in size over a period of 2 months. On palpation, the testicle had a firm consistency, with no sensitivity to digital pressure, was adhered to the scrotum and measuring 16 cm × 8 cm. In the ultrasound examination, it presented a heterogeneous texture and areas of hypoechogenic echogenicity without visualization of the mediastinum. Therefore, the bilateral orchiectomy was performed. After the surgical procedure, it was found that the affected testicle presented a firm mass measuring 9 cm × 7 cm × 3.5 cm. Histologically, a multilobulated, non‐encapsulated and invasive tumour mass was found, which replaced the seminiferous tubules, consisting of polygonal cells arranged in a mantle that varied from cohesive to loosely cohesive, supported by a scarce fibrous stroma. In the immunohistochemical examination, the neoplastic cells showed positive immunolabelling for OCT4 and C‐KIT. In this report, the physical examination combined with the ultrasonographic examination were fundamental to the therapeutic management of the case, and the final diagnosis was made after histopathological and immunohistochemical tests.

Introduction: Recognizing testicular torsion is extremely important in patients presenting to the emergency department (ED) with acute scrotal pain. Traditional manual detorsion techniques are frequently employed by emergency physicians but are not always successful. Delays in detorsion increase the risk of testicular infarction and infertility, and the need for orchiectomy. Novel techniques such as the testicular traction technique have been described as a potential solution for difficult-todetorse testicles. Case Report: Our case report describes a 20-year-old male with no significant past medical history who presented to a rural ED with acute, atraumatic testicular pain secondary to testicular torsion with an intact cremasteric reflex. After confirming the diagnosis using Doppler ultrasound, manual detorsion using the traditional “open book” technique was attempted and unsuccessful. The patient was subsequently successfully detorsed using the novel testicular traction technique. Conclusion: The testicular traction technique is a safe, rapid, and effective primary or adjunctive technique in manual testicular detorsion. Given the time-sensitive nature of testicular torsions, adjunctive techniques play a crucial role in managing challenging detorsions, particularly in resource-limited rural settings with limited access to urologic services. Although it is commonly thought that the cremasteric reflex is absent in testicular torsions, it may be present in rare circumstances, and its presence should not be an absolute in ruling out torsion.

Sterilization and castration have been synonyms for thousands of years. Making an animal sterile meant to render them incapable of producing offspring. Castration or the physical removal of the testes was discovered to be the most simple but reliable method for managing reproduction and sexual behavior in the male. Today, there continues to be global utilization of castration in domestic animals. More than six hundred million pigs are castrated every year, and surgical removal of testes in dogs and cats is a routine practice in veterinary medicine. However, modern biological research has extended the meaning of sterilization to include methods that spare testis removal and involve a variety of options, from chemical castration and immunocastration to various methods of vasectomy. This review begins with the history of sterilization, showing a direct link between its practice in man and animals. Then, it traces the evolution of concepts for inducing sterility, where research has overlapped with basic studies of reproductive hormones and the discovery of testicular toxicants, some of which serve as sterilizing agents in rodent pests. Finally, the most recent efforts to use the immune system and gene editing to block hormonal stimulation of testis function are discussed. As we respond to the crisis of animal overpopulation and strive for better animal welfare, these novel methods provide optimism for replacing surgical castration in some species.

Bovine pain assessment relies on validated behavioral scales related to normal and pain-related behaviors. This study investigated the reliability and applicability of real-time and video-recorded pain assessment, and their agreement, in young, adult bulls undergoing surgical castration. Ten Nelore and nine Angus bulls underwent general anesthesia and surgical castration. Three-minute real-time observations and simultaneous videos were recorded at − 48 h (M0), before sedation, under fasting (M1), after surgery, 3 h after sternal recumbency (M2), after rescue analgesia (M3) and at 24 h (M4). Animals received morphine (after M2), dipyrone (after M3), and flunixin meglumine after surgical castration (M4). Two trained evaluators assessed real-time (n = 95) and video-recorded time-points (n = 95) using the Unesp-Botucatu Cattle Pain Scale (UCAPS). Both assessment methods inferred 'very good' reliability (≥ 0.81) with minimal bias, however, video-recorded assessment (4.33 ± 2.84) demonstrated slightly higher scores compared to real-time (3.08 ± 2.84). The results from this study suggest that UCAPS can be used in real-time or video-recorded to assess pain and guide analgesic therapy in cattle. [ABSTRACT FROM AUTHOR]

BACKGROUND & OBJECTIVE: Acute testicular pain requires emergency exploration for suspected testicular torsion (TT). It has been suggested that temperature variation is associated with TT. However, it was not possible to conclude whether the higher occurrence of TT was related to TT itself or the effect of the overall higher presentation of acute scrotum. We studied the impact of seasonal and daily temperature variations on acute testicular pain and outcomes. METHODOLOGY: Acute testicular pain requires emergency exploration for suspected testicular torsion (TT). It has been suggested that temperature variation is associated with TT. However, it was not possible to conclude whether the higher occurrence of TT was related to TT itself or the effect of the overall higher presentation of acute scrotum. We studied the impact of seasonal and daily temperature variations on acute testicular pain and outcomes. RESULTS:In total, 502 patients required testicular exploration. The median age and duration of symptoms were 16.4 yrs. (1.3 - 77) and 4 hrs. (1 - 336). Respectively, TT was found in 231 (46%), torsion of the testicular appendix (TTA) in 126 (25%), epididymal inflammation (EI) in 46 (9.2%), and no identifiable cause (NIC) was found in 99 (19.7%). Scrotal explorations were more common in groups with mean daily temperature >6.20C, 60.2% Vs 39.8% while there was no difference in TT 46% Vs 46% in these groups. CONCLUSION: There was no seasonal variation for testicular torsion or operative findings. Cold weather and average low daily temperatures were not related to testicular torsion.

OBJECTIVE: To investigate differences in pain management between dogs and cats after surgical sterilization. We hypothesized that dogs would be more likely to be discharged with analgesics after sterilization compared to cats and that owner compliance would be better in dogs. ANIMALS: 175 respondents owning 92 dogs and 83 cats from a high-volume, low-cost veterinary clinic in Michigan during August 2022. METHODS: Owners received an online survey designed to assess their pet's postoperative analgesic care. They were asked demographic information about themselves and their pets. Additionally, they were asked if their pet was discharged with analgesics, if they were administered as prescribed, and if their pet was painful at home. Dogs and cats were included if they were sterilized within 6 months of survey completion and in the owner's care at the time of the procedure. RESULTS: The survey was distributed to 5,241 owners and received 227 responses, a response rate of 4.4%. Analgesics were prescribed for 19 of 162 (12%) pets: 14 of 88 (16%) dogs and 5 of 74 (6.7%) cats. There was no difference in the prescription of analgesics between dogs and cats after ovariohysterectomy (P = .09) or orchiectomy (P = .73). 15 of 19 owners reported their compliance in administering analgesics at 78.9%. Owners' subjective assessments showed that 24 of 86 (28%) dogs and 12 of 68 (17%) cats appeared painful at home. CLINICAL RELEVANCE: Postoperative pain in cats may not be appropriately managed.

Simple Summary: In our retrospective study at a tertiary centre, we reviewed the use of contrast-enhanced ultrasound (CEUS) and strain elastography (SE) as adjuncts to conventional greyscale and colour Doppler US (CDUS) for evaluating focal testicular abnormalities over a decade. This study highlights the potential of advanced ultrasound techniques to provide deeper insights into the characteristics of testicular abnormalities. In particular, we observed that contrast-enhanced ultrasound could detect vascular enhancement in all malignant cases, even those not identified by conventional CDUS, and more conclusively confirm benignity. While SE alone offered no distinctive advantage, incorporating a combination of CEUS and SE into the evaluation of focal testicular abnormalities improved diagnostic performance metrics over conventional CDUS. Our research underscores the enhanced performance achieved by utilising these advanced ultrasound techniques. The comprehensive diagnostic assessment provided by these techniques could facilitate a shift towards more conservative management of testicular lesions, supporting the preference for organ-preserving methods over more radical surgeries. Conventional ultrasonography (US), including greyscale imaging and colour Doppler US (CDUS), is pivotal for diagnosing scrotal pathologies, but it has limited specificity. Historically, solid focal testicular abnormalities often led to radical orchidectomy. This retrospective study evaluated the utilisation of contrast-enhanced ultrasound (CEUS) and strain elastography (SE) in investigating intratesticular focal abnormalities. A total of 124 cases were analysed. This study underscored the superior diagnostic capabilities of CEUS in detecting vascular enhancement in all malignant cases, even those with undetectable vascularity by CDUS. It also highlighted the potential of CEUS in identifying distinctive vascular patterns in benign vascular tumours. Definitive confirmation of benignity could be obtained when the absence of enhancement was demonstrated on CEUS. While SE alone offered no distinctive advantage in differentiating between benign and malignant pathologies, we demonstrated that incorporating a combination of CEUS and SE into the evaluation of focal testicular abnormalities could improve diagnostic performance metrics over conventional CDUS. Our findings underscore the role of advanced ultrasound techniques in enhancing the evaluation of focal testicular abnormalities in clinical practice and could aid a shift towards testis-sparing management strategies.

Since bucks are raised mainly for meat, there is a need for castration to optimize meat production. In this study, we conducted a comparative evaluation of the serum biochemical profiles of red Sokoto bucks following Burdizzo castration, in situ spermatic cord ligation, and orchidectomy. Sixteen red Sokoto bucks aged 6 months to 1 year old and 11-12 kg body weight were used for this study. The bucks were randomly divided into 4 groups of 4 bucks each as follows; group A (Burdizzo), B (in situ spermatic cord ligation), C (orchidectomy), and D (control). Blood was collected pre-castration, and at immediate, 4, 8, 12, 16, 20, 24, 32, 48, and 72 hours post-castration (HPC) into labeled tubes without anticoagulant, serum was harvested and used for serum biochemical analyses. The outcomes showed non-significant changes in total protein, sodium, chloride, calcium, and potassium levels in all groups of bucks. Glucose levels were significantly increased at immediate PC in groups A, B, and C, followed by a decline from 4 HPC to normal values by 16 HPC (group B) and 20 HPC (group A). The serum creatinine levels increased significantly at immediate PC, peaked at 20 HPC, and declined from 24 HPC. The blood urea nitrogen level increased significantly from immediate PC up to 72 HPC. The activities of superoxide dismutase, glutathione peroxidase, catalase, and malondialdehyde levels increased significantly from 4 HPC, peaked at 16 to 20 HPC, and decreased from 24 to 72 HPC. There were less severe serum biochemical changes by Burdizzo castration and in situ spermatic cord ligation compared to orchidectomy in the red Sokoto bucks. [ABSTRACT FROM AUTHOR]

Telocytes are CD34+ interstitial cells that have long cytoplasmic projections (called telopodes), and have been detected in several organs, including those of the male reproductive system. In this brief review we evaluate the role of telocytes in tissue organization of the different organs of the male reproductive system in which these cells were studied. In general terms, telocytes act in the tissue organization through networks of telopodes that separate the epithelia from the stroma, as well as dividing the stroma into different compartments. In addition to this contribution to the structural integrity, there is direct and indirect evidence that such “walls” formed by telocytes also compartmentalize paracrine factors that they or other cells produce, which have a direct impact on morphogenesis and the maintenance of organ cell differentiation, as well as on their normal physiology. Moreover, alterations in telocytes and telopode networks are correlated with pathological conditions in the male reproductive system, in response to profound changes in structural organization of the organs, in inflammation, hyperplasia and cancer. Further studies are necessary to evaluate the molecular pathways telocytes employ in different contexts of physiology and disease.

IntroductionStallion castration is a standard procedure with a risk of post-surgical complications. Castration induces an acute phase response (APR). Serum Amyloid-A (SAA) is a well-studied major acute phase protein (APP), that has been shown to be a good marker for the development of post-surgical complications. The current gold standard for reducing the APR after castration is Flunixin-Meglumin, which is a non-steroidal anti-inflammatory drug (NSAID) inhibiting COX1/2. In contrast, Traumeel LT ad us. vet. can modulate the APR by induction of the inflammation resolution. The aim of this study was to compare the effect of Flunixin-Meglumin and Traumeel LT ad us. vet. on the acute phase response.Material and methodsA total of 60 stallions were recruited and 54 stallions entered the study with 27 stallions in each treatment group. The stallions were treated pre- and postoperatively with either Flunixin-Meglumin (FL) or with Traumeel LT ad us. vet. (TR). Blood was taken before and 24 h, 48 h and 72 h after castration. The following main parameters were assessed: SAA, fibrinogen, iron, white blood cells, neutrophils, Interleukin1ß, and cortisol. Wound healing and pain were assessed at 8 time points.ResultsThe main variable SAA was increased after surgery reaching a mean value of 122 µg/ml in the FL group and a mean SAA of 226 µg/ml in the TR group 48 h after surgery, reaching a significant difference only at the 24 h timepoint (p = 0.03). All stallions had the highest pain summary score 8 hours after surgery, with decreasing values thereafter. The pain scores were not statistically different at any time point. In the FL group five stallions developed a suture dehiscence compared to only one stallion in the TR group (p = 0.001).DiscussionWithin the limitations of this study, Traumeel LT ad us. vet. seems to have proresolving effects on the inflammation induced by surgery making it a valuable treatment to reduce the APR induced by castration. Due to its different mode of action, Traumeel LT ad us. vet. might be an alternative treatment option if gastrointestinal side effects or renal side effects of NSAIDs should be avoided.
