SUMMARY OBJECTIVE: The aim of this study was to evaluate the quality of life of patients with lifelong and acquired premature ejaculation and to examine its relationship with depression and anxiety. METHODS: Between February 2017 and January 2018, a total of 175 patients with premature ejaculation and 132 control men who applied to the urology department of the training and research hospital with the complaint of Premature Ejaculation were included. Patients were divided into three groups according to International Society for Sexual Medicine (ISSM) criteria as follows: Group 1, lifelong premature ejaculation; Group 2, acquired premature ejaculation, and Group 3, control group without premature ejaculation. A detailed medical history of patients was obtained and physical examinations were performed. Intravaginal ejaculation latency time (IELT) was recorded and patients were administered International Erectile Function Index-5 (IIEF-5), Premature Ejaculation Diagnostic Tool (PEDT), Sexual Health Inventory for Men (SHIM), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI)-1 and STAI-2, and Short Form-36 (SF-36). RESULTS: The mean mental component score (MCS) of the SF-36 was 51.65±6.57 in the lifelong premature ejaculation group, 49.33±8.65 in the acquired premature ejaculation group, and 61.12±11.09 in the control group (p

Mean platelet volume (MPV) has been related to erectile dysfunction (ED). However, its value in predicting therapeutic response to phosphodiesterase-5 inhibitors is not evaluated. This study aimed to investigate the value of MPV as a marker for the prediction of the response of the tadalafil treatment of ED. A retrospective analysis of patients who were admitted to the andrology outpatient clinic between 2020-2022 were performed. The inclusion criteria were, ≥40 years old male, International Index of Erectile Function-Erectile Function domain score 26, not received any ED treatment before, have a stable heterosexual relationship, and prescribed 5 mg daily tadalafil for primary treatment of ED. A total of 116 patients were included in the study. The mean age of the patients was 53.7 ± 8.7 years. The response rate to 5 mg tadalafil treatment was 52.6% (Group-1; N = 61). An MPV value

Aside from the ordinary plasma lipid level measurements, the ratios based on individual plasma lipid levels such as atherogenic index of plasma (AIP), Castelli's risk index 1/2 (CRI-1/2), and atherogenic coefficient (AC) are the novel parameters to evaluate the patients with a high risk of CVD. In this study, we aim to evaluate the relationship between AIP, AC, and CRI-1/2 with increased risk of ED. Between April 2018 and February 2019, 253 patients, who were diagnosed as a vasculogenic ED in our clinic, were enrolled in the study. While the first group (

The aim of this study was to evaluate the effect of vitamin D replacement in patients with lower urinary tract symptoms (LUTS)/erectile dysfunction (ED) who did not respond to tadalafil 5 mg treatment. Patients who applied to the Andrology Clinic with LUTS/ED between September 2017 and August 2020 and used 5 mg Tadalafil daily for treatment and did not benefit from treatment for 1 month were included in the study. Vitamin D levels of the patients were analysed and Vitamin D3 100,000 IU/week oral therapy was administered for a month to the patients with low levels of Vitamin D(20 ng/ml).The values of the patients before and after Vitamin D replacement were compared. A total of 84 patients were included in the study. The mean age was 49.175 ± 11.63(28-70) years and the mean BMI was 25.93 ± 6.82(18.26-37.87). Testosterone levels of the examined patients were 3.45 ± 0.99 ng/ml. After 1 month of Vitamin D replacement + Tadalafil 5 mg/d treatment, the international index of erectile function-erectile function (IIEF-EF) (pre-treatment: 10.73 ± 6.12, post-treatment: 24.18 ± 4.87; p = 0.001) and International Prostate Symptom Score (pre-treatment: 9.12 ± 7.16, post-treatment: 3.11 ± 1.08; p = 0.003) scores of the patients improved significantly. Evaluation of Vitamin D levels is important to improve treatment response, especially in patients who do not respond to PDE-5 inhibitors.

Overactive bladder (OAB) is a syndrome with symptoms such as urinary frequency, urinary urgency and urge incontinence. The aim of this study is to assess the validity and reliability of the Turkish overactive bladder symptom score (OABSS) and to evaluate the results of mirabegron treatment with OABSS. The study was carried out with 117 patients who applied to the urology outpatient clinic between June 2018–January 2019. OABSS Turkish validation was developed from the English version. Demographic data of the patients were recorded. The OABSS, overactive bladder questionnaire (OAB-v8) and International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) were filled out by the patients. The patients were asked to fill in these questionnaires after 2 weeks. Patients receiving mirabegon treatment were evaluated with the same questionnaires and bladder diaries after 8 weeks. A total of 117 OAB patients, including 82 OAB-wet and 35-OAB dry, were included in the study. The mean age of the patients was 46.79 ± 14.26 (18–78) years, and the mean duration of OAB complaint was 32.28 ± 32.21 months. The mean score of the OABSS is 9.9 ± 3.14. The results of the reliability assessment showed that the intraclass correlation coefficient of the total OABSS score was 0.71 (weighted coefficients of individual item points, 0.635–0.831), and the Cronbach α was 0.736. In the validity analysis, the OABSS total score was highly correlated with that belonging to other questionnaire forms (OAB-v8, ICIQ-SF and bladder diary). After the treatment with mirabegron, mean OABSS scores of the patients improved significantly from baseline to the 8th week (p

Aim and objectives The aim of this was to examine the effect of bladder training on bladder functions. Background Urinary catheterization is frequently performed in order to evaluate the outcomes of the surgical procedures and to monitor the urine output after urology operations. Design and methods This quasi-experimental study was conducted in the urology clinic in Istanbul, Turkey in which 50 males were nonrandomly assigned to either a bladder training (n = 28) or a control group (n =22). In the bladder training groups, the urinary catheters of the patients were clamped at 4-hr intervals and then were left open for 5 min on the second postoperative day. This study was created in accordance with TREND Statement Checklist. Results The first urgency time and the first voiding time were longer, and the prevoiding and the voiding volumes were higher following the removal of the catheter in the training group (p = 0.001). In addition, the evaluation of the patient bladder diaries in the first three days after the discharge period revealed that the daily frequencies of micturition and nocturia were lower (p = 0.04), the mean duration of intervals between the micturition was longer (p = 0.006), and the mean voided urinary volume was higher (p = 0.024) in the training group. Conclusion At the end of the study, it is observed that bladder training performed by clamping the catheter on postoperative day 2 after Transurethral Resection of Prostate (TUR-P) operation is a significant positive effect on the storage symptoms of the patients. Relevance to clinical practice Before removing the urinary catheter, bladder training programme affects positively to patients, especially prevoiding and the voiding volumes, the daily frequencies of micturition and nocturia on postoperative periods.

Introduction Even though lifelong premature ejaculation (PE) is highly prevalent, few studies have investigated the neural mechanisms underlying PE. Aim This study aimed to investigate whether patients with lifelong PE exhibit macrostructural or microstructural alterations of the parts of the brain involved in the male sexual response. Materials and Methods We enrolled 42 healthy participants and 54 lifelong PE patients. Lifelong PE was diagnosed according to the Premature Ejaculation Diagnostic Tool (PEDT) and intravaginal ejaculation latency time (IELT). We compared measures of cortical morphology, such as volumes of gray matter, white matter, cerebellum volumes, and subcortical structures (ie, amygdala, caudate, hippocampus, globus pallidus, putamen, and thalamus) between the groups using a voxel-based morphometry method from whole-brain T1-weighted magnetic resonance imaging. Moreover, we evaluated the relationships between the relevant cerebral alterations and the severity of symptoms obtained from participants via self-reported questionnaires. Main Outcome Measures Cerebral macrostructural and microstructural alterations were assessed in PE patients and controls, along with the correlation of caudate nucleus changes in PE patients with clinical data (including the PEDT and the IELT). Results The mean volume of the caudate nucleus was significantly larger in the lifelong PE patients compared with healthy controls (P = .048). Moreover, caudate nucleus volume was positively correlated with PEDT score (r = 0.621; P = .0179) and negatively correlated with the IELT (r = −0.592; P = .0101). However, cortex morphology and the other subcortical volumes were not significantly different between the 2 groups (P > .05). Clinical Implications Microstructural alterations in deep gray matter nuclei might be a useful parameter for studying the mechanism of the neurobiology underlying PE. Strengths and Limitations There are few studies examining microstructural changes in PE patients. This study furthers our understanding of the etiology of PE. Limitations include the small sample, which limits our ability to make an absolute determination as to whether such subcortical changes are the cause or the consequence of lifelong PE. Conclusions We found a significant difference in caudate nucleus volume between patients with PE and healthy controls. In addition, the caudate nucleus volume was positively associated with the severity of PE symptoms. More extensive and possibly longitudinal studies are needed to improve our understanding of the mechanism of the neurobiology underlying PE.

Erectile dysfunction (ED) is seen very often in the men with type 2 diabetes mellitus (DM). Due to the ability of vitamin D to reduce endothelial damage and oxidative stress, its role in preventing cardiovascular risk has been demonstrated in some studies. Since ED and cardiovascular disease have common pathogenic mechanisms, many studies have evaluated a possible relationship between vitamin D deficiency and ED. Total 120 patients with type 2 diabetes mellitus were evaluated in this study. Vitamin D and HbA1c values were statistically compared according to International Index of Erectile Dysfunction (IIEF-5) scores. 23.3% of 120 patients had mild, 38.3% had mild to moderate, 21.7% had moderate and 16.7% had severe ED. There was statistically difference in vitamin D levels of the patients according to IIEF-5 scores. Also, significant difference was found in HbA1c levels between the patients with severe ED and other groups. Cut-off point for vitamin D and HbA1c were determined according to IIEF-5 score in patients who were divided in to two groups (14.41 and 11.1). A statistically significant correlation was found between both cut-off points and IIEF-5 scores. Our study shows that patients with ED have a vitamin D deficiency and a poor glycemic control.

AIM To assess the functions of the lower urinary tract (LUT) in patients with myasthenia gravis (MG). MATERIALS AND METHODS A total of 36 patients (18 males and 18 females) with MG and 29 healthy controls were enrolled. Participants completed a 3-day voiding diary and responded to questionnaires "Overactive Bladder Symptom Score" (OABSS) and "International Consultation on Incontinence-Short Form" (ICIQ-SF). All patients underwent uroflowmetry and ultrasonography (US). The data were compared based on the onset of disease and serological status. RESULTS The most common urinary symptoms were nocturia (80.5%), incontinence (61%) and urgency (47%). OABSS was higher in patients than controls (P = .008). Duration of urinary symptoms was longer, and nocturia was more common in late-onset MG (LOMG) than in early-onset MG (EOMG; P = .029, P = .023). The duration of disease and urinary symptoms statistically increased in ACh-Ab (-) group compared with ACh-Ab (+) group (P = .003, P = .027). Night-time urination frequency significantly increased while daytime voided volume (VV) decreased in LOMG compared with EOMG (P = .003 and P = .01). Residual volume on the US was significantly higher in LOMG than that in EOMG (P = .004). The duration of disease was positively correlated with tQmax and daytime urination frequency (P = .013, r = .48; P = .016, r = .398). A negative association was found between duration of disease and daytime VV (P = .04, r = -.344). CONCLUSION LUT dysfunction may manifest disease in MG, particularly in late-onset forms. The lack of ACh-Ab seemed to prolong the duration of disease and urinary disturbances.

Aetiologic and predisposing factors are still controversial about Peyronie's disease (PD). However, it is thought to be the result of connective tissue disorder or healing defect. Androgens are known to affect collagen metabolism and wound healing in the body. The aim of this study was to investigate the relationship between PD and low testosterone levels. One hundred and forty-seven Peyronie patients and 137 healthy volunteers were included in the study. In both groups, demographic data, medical history, physical examination and erectile capacity were recorded. Blood samples were collected from all subjects in the early morning hours after an overnight fast. The mean level of serum total testosterone was lower in men with PD compared with the controls (3.9 ± 1.1 vs. 4.2 ± 1.7 ng/ml respectively) (p = .062). However, statistically significant relationship was not found between PD and low serum testosterone levels. There was no significant correlation between penile plaque dimension or penile curvature degree and testosterone levels. Large randomised-controlled prospective studies are needed to reveal this possible association.

We aimed to investigate the pre-operative predictive role of haematological parameters in patients with testicular torsion. The medical records of patients operated between January 2016 and November 2018 were retrospectively analysed. The demographic characteristics and complete blood count of the patients were recorded. We divided the patients who operated with testicular torsion into two groups: detorsion (Group 1) and orchiectomy (Group 2). A control group (Group 3) was created from healthy volunteers. All haematological parameters and other demographic data were compared between three groups. A total of 144 participants were included; Group 1, Group 2 and Group 3; 61, 27 and 56 respectively. The duration of symptoms and monocyte counts were found statistically significantly higher in patients undergoing orchiectomy than detorsion (p

Background The aim of this study is to evaluate the validity and reliability of the Targeting the Individual's Aetiology of Nocturia to Guide Outcomes (TANGO) screening tool, which is used to determine nocturia etiology. Methods Patients hospitalized in urology, orthopedics, and general surgery clinics between September 2019 and January 2020 were included in the study. Demographic characteristics of the participants such as age, gender, drug use, and nocturia severity were assessed by the researchers. The Turkish version of the TANGO questionnaire consisting of 22 questions was filled in by the patients. The patients were asked to repeat the same test 4 weeks later. Results A total of 124 patients were included in the study. The mean age of the patients participating in the study was 51.20 ± 18.50 (38-82). The result of the reliability assessment showed that the total score intraclass correlation coefficient was 0.715 (individual item score weighted kappa coefficients, 0.696-0.731) and the Cronbach's alpha coefficient was 0.727. A total of 112 patients filled in the TANGO screening tool again after 4 weeks. The test-retest reliability analysis kappa value was 0.75 (0.68-0.83). In the validity analysis, a moderately positive correlation was observed between the TANGO-Urinary Incontinence Score and the number of nocturia (r = 0.452, P = .003). Conclusion According to the validation study, the TANGO screening tool is valid and reliable to determine the nocturia etiology for the Turkish population.

Testicular sperm extraction is a common surgical procedure to retrieve spermatozoa from men with azoospermia which may affect the tissue and cause hypogonadism (Human Reproduction Update, 24, 2018, 442). We aimed to evaluate the acute effect of micro-TESE on blood total testosterone (TT) and luteinising hormone (LH) levels. Between April 2018 and September 2019, 60 selected NOA (i.e. with normal TT and LH) patients were included in the study. After procedure, blood samples were collected to evaluate the levels of TT and LH at 1st and 24th hour and first week. Values were compared. In addition, patients were divided into two groups according to their body mass index. Mean age of patients was 27.37 ± 4.52 years, and mean of body mass index was 24.49 ± 3.78 kg/m2 . Mean TT levels at the 1st hour, 24th hour and the 1st week were 3.81, 3.50 and 3.05 ng/ml respectively. Mean LH levels at the 1st hour, 24th hour and the 1st week were 5.03, 5.15 and 5.46 IU/L respectively. Statistically significant differences between pre- and post-operative 24th hour and 1st week values were detected (p = .001, p < .001 respectively). No statistical differences were found between two BMI's groups. TT decreased in acute period after the procedure, whereas the increase of LH levels was observed after 24th hour.

In our study, we examined the effect of the three-dimensional (3D) stone segmentation volume and its ratio to the renal collecting system on complication rates. Data from141 patients who underwent PCNL surgery were analyzed retrospectively. Volume segmentation of both the renal collecting system and stones was obtained from 3D segmentation software with the images on CT data. After creation of a 3D surface volume rendering of renal stones and the collecting system, segmentation of the renal collecting system volume (RCSV) and analyzed stone volume (ASV) was analyzed and the ASV-to-RCSV ratio was calculated. Univariate analysis and multivariate logistic regression model were used to determine factors that affected complication status. Diagnostic value for the prediction of complication rates was analyzed using receiver operating characteristic (ROC) incline. Overall, there were 141 (92 male and 49 female) eligible patients included in the current study. The overall complication rate for PCNL monotherapy was 31.9%. Multivariate regression analysis (forward stepwise) revealed that the ASV-to-RCSV ratio and number of tracts were independent risk factors for developing complications (OR 1.17, p

Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS) is often associated with erectile dysfunction (ED). However, the underlying pathophysiological mechanisms of ED occurrence are still unclear in patients with CP/CPPS. The aim of the study was to investigate superoxide anion (O2•−) and total reactive oxygen species (ROS) production in semen of men with category IIIA CP/CPPS and their association with ED. This prospective study included 33 men with category IIIA CP/CPPS. Control group consisted of 13 healthy men. Total ROS and O2•− production were assayed by luminol and lucigenin-dependent chemiluminescence (CL) methods, respectively. ED was evaluated using the IIEF-5 questionnaire. Patients with CP/CPPS had significantly higher seminal total ROS and O2•− levels than healthy control subjects (2.9 ± 0.5 relative light unit (RLU) vs. 2.4 ± 0.2 RLU, p

Background: The aim of this study was to evaluate the relationship between mean platelet volume (MPV) and vitamin D levels according to ED severity.Methods: Between October 2015 and September 2017,...

Purpose: To identify the factors increased fluoroscopy time during percutaneous nephrolithotomy and investigate the relationship between the 3D segmentation volume ratio of stone to renal collecting system and fluoroscopy time. Materials and Methods: Data from 102 patients who underwent percutaneous nephrolithotomy were analyzed retrospectively. Volume segmentation of both the renal collecting system and stones were obtained from 3D segmentation software with the images on CT data. Analyzed stone volume (ASV), renal collecting system volume (RCSV) measured and the ASV-to-RCSV ratio was calculated. Several parameters were evaluated for their predictive ability with regard to fluoroscopy time. Results: The stone-free rate was 55.9% after the percutaneous nephrolithotomy. Complications occurred in 31(30.4%) patients. The mean fluoroscopy time was 199.4±151.1 seconds. The fluoroscopy time was significantly associated with the ASV-to-RCSV ratio (p

Although premature ejaculation (PE) is a common male sexual dysfunction, its pathophysiology has not been fully elucidated. Several medical problems such as erectile dysfunction, depression, anxiety, hormonal disorders and chronic prostatitis may play a role in the etiology of acquired PE. This study aims to evaluate the frequency of these etiologic factors among patients with acquired PE. Between May and July 2016, 53 men with acquired PE were included in the study. Self-estimated intravaginal ejaculation latency time (IELT) of these patients was recorded along with their medical history and physical examination findings. Moreover, 5-item version of the International Index of Erectile Function (IIEF-5), premature ejaculation profile (PEP), anxiety and depression scales (STAI-1, STAI-2, and BECK), and chronic prostatitis symptom index (NIH-CPSI) were administered. Fasting plasma glucose, follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin, total and free testosterone, total prostate specific antigen, thyroid and thyroid stimulating hormone levels were measured. Urine analysis and 2 cup tests were also studied. Mean age of the patients was 42.41 ± 11.14 (22–60). Mean duration of the PE complaint was 34.18 ± 36.76 (3–144) months. Mean IELT time of the patients was 38.28 ± 30.79 (3–180) s. Of the patients; 69.81%, 62.26%, 56.60%, 45.28%, 30.19%, 24.53%, 16.98%, 15.09%, and 7.55% had depression, chronic prostatitis, erectile dysfunction, anxiety, diabetes mellitus, abnormal FSH or LH, hypoprolactinemia, hyperthyroidism, and high testosterone levels, respectively. The results of our study revealed that anxiety disorders, depression, erectile dysfunction, and chronic prostatitis are common among patients with acquired PE and may play role in the etiology of this problem. There is a need for further researches related to the exact pathophysiology of acquired PE with larger number of patients.

The aim of this study is to investigate whether serum vitamin D level predicts the risk of Peyronie's disease. Calcium and inflammatory cytokines play an important role during fibrocalcification of the plaques in Peyronie's Disease. TGF-β1 is one of the most fibrogenic cytokines. Increasing serum vitamin D levels is considered that induce expression of TGF-β1. Serum vitamin D levels and TGF-β1 are related with calcifications of some soft tissues in previous studies. One hundred and three Peyronie patients and 162 healthy volunteers were included in the study. In both groups, demographic data, medical history, physical examination and erectile capacity were recorded. Serum 25-hydroxyvitamin D, total cholesterol, low-density lipoprotein, high-density lipoprotein, triglyceride and testosterone levels were measured. The mean level of serum 25 (OH) D was significantly higher in men with Peyronie's disease compared with the controls (32.6 ± 7.9 ng/ml vs. 18.5 ± 6.6 ng/ml respectively. p < 0.001). There is a relationship between Peyronie's disease and high serum vitamin D levels. Also, increased low-density lipoprotein and total cholesterol levels, diabetes mellitus, and cardiovascular diseases were associated with Peyronie's disease.

Premature ejaculation (PE) and erectile dysfunction (ED) are the most prevalent sexual disorders in men. ED is commonly reported among patients with PE. Although recent guidelines recommend to treat ED first in men with both PE and ED, this recommendation is not based on evidence and there are limited data about the efficacy and safety of dapoxetine/sildenafil combination therapy for these patients. The aim of this study is to evaluate the clinical efficacy and safety of the dapoxetine/sildenafil combination (Dapoxil® 30/50 mg film-coated tablet) in the treatment of patients with PE and concomitant ED. In a single-center, single-arm, open-label clinical study conducted between October 2016 and September 2017, 74 patients with lifelong or acquired PE and ED were included. All patients were instructed to record their intravaginal ejaculatory latency time (IELT) with a stopwatch for 4 weeks. After the screening, they were requested to complete Premature Ejaculation Diagnostic Tool (PEDT), Premature Ejaculation Profile (PEP), and International Index of Erectile Function-Erectile Function (IIEF-EF) questionnaires before the treatment. The patients received on demand Dapoxil® 1–3 h before sexual intercourse for the next 4 weeks (2 days a week and no more than once a day). The patients were also assessed with global impression of change (GIC) question for the treatment satisfaction and the side effects were recorded. The study was completed with 53 patients (53/74, 71.62%). Mean age of the patients was 45.32 ± 10.05 years. At the end of the 4-week treatment period, the geometric mean IELT of the patients significantly increased (from 22.72 ± 15.16 to 68.25 ± 82.33 s; p

Purpose: The objective of this study was to evaluate the effects of intratunical injection of platelet rich plasma (PRP) for the treatment of Peyronie’s disease (PD) in a rat model. Materials and Methods: Twenty male Sprague-Dawley rats (300–350 g) were randomly divided into 4 groups: sham, PD, PD + PRP, and PRP. The PD + PRP groups received intratunical injections with 0.1 mL PRP on day 15 (treatment) or day 0 (PRP effect). Forty-five days following transforming growth factor-beta 1 injection, rats underwent pathological examination. Tissues were evaluated histologically for fibrosis grade (Haematoxylin & Eosin staining), collagen/smooth muscle ratio (Masson Trichrome staining) and type III/type I collagen ratio (Picro-sirius red staining). Statistical analysis was performed by Kruskal-Wallis and chi-square followed by the Mann-Whitney U test for post hoc comparisons. Results: Significant changes were found in all 3 groups compared to the sham group (p < 0.0001 for fibrosis, p = 0.001 for collagen/smooth muscle ratio and p = 0.003 for type III/type I collagen ratio). The values in the PRP group and the findings in the PD group are similar (p = 0.122 for fibrosis, p = 0.221 for collagen/smooth muscle ratio and p = 1.0 for type III/type I collagen ratio). Conclusion: This is the first study of PRP on PD. As a result of pathological examinations, PRP shows PD-like effects in rats. PRP may be a cheap, easily accessible, and an effective disease model for PD treatment research.

Introduction 5-Alpha reductase inhibitors (5-ARIs) are widely used in the treatment of benign prostatic hyperplasia (BPH) and androgenic alopecia (AGA). Aim To examine all available data on the effects of 5-ARIs on sexual functioning in AGA treatment and to assess whether 5-ARIs increase the risk of sexual dysfunction. Methods A literature review of publications at PubMed related to the subject was used. Main Outcome Measure We assessed erectile dysfunction, ejaculation impairment, and decreased libido. Results 5-ARIs may cause side effects such as erectile dysfunction, ejaculation problems, and decreased libido in patients. Their long-term impact and precise mechanism have not been clarified. Data from studies on 5-ARIs are important for drug selection and patient counseling. More training and awareness is needed for clinicians and patients to recover many patients from sexual adverse effects. Conclusion 5-ARIs used in the treatment of AGA have well-defined side effects, which can negatively affect sexual life. It is unknown and unpredictable which men using these drugs may be subject to these side effects and when these effects may appear. Studies have been insufficient to provide a clear answer to this question. Coskuner ER, Ozkan B, Culha MG. Sexual Problems of Men With Androgenic Alopecia Treated With 5-Alpha Reductase Inhibitors.

Myiasis is a parasitic infestation of vertebrate animals caused by the eggs and larvae of flies within the Diptera species. Psychoda albipennis is a rare cause of urogenital myiasis in humans. We present the case of a 42-year-old male diagnosed with urogenital myiasis caused by Psychoda albipennis . Saudi Med J 2016; Vol. 37 (12): 1401-1403 doi: 10.15537/smj.2016.12.16312

The aim of this prospective, observational study was to investigate the relationship between premature ejaculation (PE) and female sexual response cycle, using the female sexual function index (FSFI). The FSFI evaluates female sexual function in six domains: desire, arousal, lubrication, orgasm, satisfaction, and pain. All men were considered to have PE if they fulfilled the criteria of the second Ad Hoc International Society for Sexual Medicine (ISSM) Committee. All men were also assessed by the Premature Ejaculation Diagnostic Tool (PEDT) and intravaginal ejaculatory latency time (IELT) using stopwatch which was held by the partner. All women completed the FSFI. A total of 181 couples who had regular sexual intercourse with one partner for the past 6 months were enrolled the study. By the definition of ISSM Committee, there were 117 men with PE and 64 men without PE. Partners of men with PE had significantly lower total FSFI scores than did partners of men without PE (21.8 ± 3.5 for PE and 26.4 ± 3.1 for non-PE, p

To compare the serum antioxidant enzyme levels between patients with urinary stone disease and healthy volunteers to determine the effect of cellular oxidative stress on urinary calcium oxalate stones formation.Materialsamp; Methods: A total of 51 patients with proven urinary calcium oxalate stones (female 35.3%, mean age: 49.3 years) and 37 healthy subjects (female 45.9%, mean age: 44.1 years) were included. The serum levels of antioxidant catalase, glutathione peroxidase, superoxide dismutase and lipid peroxidation were measured in serum samples taken from the peripheral venous circulation.Mean serum catalase level of patient group was insignificantly higher than healthy subjects (7.54 mmol- H2O2/mg/sec versus 6.16 mmolH2O2/mg/sec, respectively; P = .06) whereas mean superoxide dismutase level (1.56 U/ml versus 3.86 U/ml, P = .047), glutathione peroxidase level (6.70 U/ml versus 8.19 U/ml, P = .022) and lipid peroxidation level (2.35 nmol/ml versus 3.31 nmol/ml, P = .034) of patient group were significantly lower than healthy subjects. Patients with family history of urinary stone disease had significantly lower mean serumlevels of catalase (P = .037), superoxide dismutase (P = .047) and glutathione peroxidase (P = .01), compared with patients without family history.The findings of this study provide evidence regarding the role of oxidative stress in the development of urinary calcium oxalate stones. Future clinical trials are necessary to elucidate the actual mechanisms of the calcium oxalate stone formation in the environment with increased oxidative stress.

Most common male reproductive disorders are linked to lower testosterone exposure in fetal life, although the factors responsible for suppressing fetal testosterone remain largely unknown. Protracted use of acetaminophen during pregnancy is associated with increased risk of cryptorchidism in sons, but effects on fetal testosterone production have not been demonstrated. We used a validated xenograft model to expose human fetal testes to clinically relevant doses and regimens of acetaminophen. Exposure to a therapeutic dose of acetaminophen for 7 days significantly reduced plasma testosterone (45% reduction; P = 0.025) and seminal vesicle weight (a biomarker of androgen exposure; 18% reduction; P = 0.005) in castrate host mice bearing human fetal testis xenografts, whereas acetaminophen exposure for just 1 day did not alter either parameter. Plasma acetaminophen concentrations (at 1 hour after the final dose) in exposed host mice were substantially below those reported in humans after a therapeutic oral dose. Subsequent in utero exposure studies in rats indicated that the acetaminophen-induced reduction in testosterone likely results from reduced expression of key steroidogenic enzymes (Cyp11a1, Cyp17a1). Our results suggest that protracted use of acetaminophen (1 week) may suppress fetal testosterone production, which could have adverse consequences. Further studies are required to establish the dose-response and treatment-duration relationships to delineate the maximum dose and treatment period without this adverse effect.
