Objective: To investigate the efficacy and safety of Compound Chamomile and Lidocaine Hydrochloride Gel (CCLH) (Kamistad) applied at different time-windows on premature ejaculation (PE)., Methods: This prospective study included 72 PE patients treated by application of CCLH to the glans and penile body in our hospital from February to October 2021. According to the time of drug administration before insertion into the vagina, we randomly divided the patients into a 5-minute group (n = 39) and a 15-minute group (n = 33). Before and after 1 and 2 weeks of treatment, we compared the intravaginal ejaculation latency time (IELT), PE diagnostic tool (PEDT) score, quality of life, and adverse reactions between the two groups of patients., Results: Totally 62 of the patients completed the follow-up, 35 in the 5-minute group and 27 in the 15-minute group, and all showed significant improvement in IELT (P < 0.01) and PEDT score (P < 0.05) after treatment compared with the baseline. No allergic reactions, such as redness and swelling, developed at the application site in any of the patients, and no adverse significant effect was observed on the erectile hardness in 61 of the cases. Six cases showed increased erectile hardness instead. Fifty-seven of the patients experienced no obvious penile numbness or reduced sexual satisfaction, and all could complete their sexual activities., Conclusion: Compound Chamomile and Lidocaine Hydrochloride Gel applied at different time-windows is effective on PE, with a 5-minute rapid onset of action before intercourse, and no obvious adverse effects.

Since the outbreak of coronavirus disease 2019 (COVID-19), more than 130,000 people worldwide have been infected. Many studies show that the testis is one of the organs with a high expression of angiotensin-converting enzyme 2 (ACE2), the receptor/binding protein of SARS-CoV-2, which has aroused public concerns about the possible damage to male fertility. This article presents a review and analysis of the existing literature, aiming to achieve an objective understanding of the significance of the ACE2 expression in the testis. Hitherto, clinical and laboratory data available on COVID-19 are not sufficient to provide any direct evidence that the testis is a target organ of the virus. Whether the coronavirus damages fertility in male patients with COVID-19 requires further investigation. In the absence of sufficient research-based evidence, damage of the virus to male fertility should not be over-interpreted.

Objective: To explore the perception of the female partner's beauty, stimulating factors for sexual arousal, and the acquisition of sexual knowledge in blind males and analyze the related influencing factors., Methods: Using a self-designed questionnaire and with the help of the Disabled Persons' Federation and the Association for the Blind of Ganzhou, we conducted an investigation among 54 blind males at an average age of 33.5 years, who met the inclusion criteria and were enrolled according to the rosters provided by the above institutions. We convened the subjects in the appointed hospitals or other places for telephone or face-to-face question-and-answer interviews with qualified investigators trained previously., Results: In the first phase, as the preliminary investigation, open-ended questions were asked of 21 of the subjects on the telephone or at a one-to-one interview. In the second phase, as the formal investigation, closed-ended questions were asked of the other 33 blind males at a face-to-face interview. The blind males perceived the beauty of their sexual partners mainly by the female's mild disposition and sweet voice (63.6% ［21/33］), soft and satiny skin (51.5% ［17/33］), sexy and well-shaped body (54.5% ［18/33］), and intoxicating bodily scent (18.2% ［6/33］). The stimulating factors for sexual arousal of the subjects included hearing the partner's soft and sweet voice (39.4% ［13/33］), feeling her satiny skin (54.5% ［18/33］), touching her sexy and well-shaped body (66.7% ［22/33］), and the pleasant mood of the males (30.3% ［10/33］)., Conclusions: The blind males in Ganzhou perceive the beauty of their sexual partners mainly by their senses of hearing, touch and smell, and the stimulating factors for sexual arousal chiefly include the partner's sweet voice, satiny skin and well-shaped body as well as the pleasant mood of the males.

Mild-symptom erectile dysfunction (MSED) is commonly seen in clinical practice, but receives inadequate attention from both the patients and clinicians. Increasing researches have indicated that MSED is associated with not only unhealthy living habits and psychological factors but also the early progression of endothelial, metabolic and endocrine diseases. The diagnosis and treatment of MSED should be based on the relevant guidelines, with consideration of both its specific and common features. The therapeutic principle is a combination of integrated and individual solutions aimed at the causes of the disease. Drug intervention should be initiated if psychological therapy fails. Negligence of MSED may affect the quality of life of the patients and their partners, and what's more, might delay the management of some other severe underlying diseases. Adequate attention to the early diagnosis and treatment for MSED is of great significance for a deeper insight into the etiology of ED, the prevention of potential cardiovascular and metabolic diseases, and the improvement of the overall health of males.

Pericyte, also known as mural cell or Rouget cell, is one of the main cells that make up the wall of capillaries. Pericytes play important roles not only in the maturation, stability, and function maintenance of blood vessels, but also in the growth and development of tissues and organs, wound repair, and other physiological and pathological processes. Researches on the functions of pericytes are mainly concentrated on their multipotency, adjustment of vascular functions, and process of fibrosis, as well as on renal fibrosis, renal blood flow regulation, and glomerular filtration in urology, but are quite insufficient in andrology. This article reviews the location, origin, distribution, morphology, markers, and functions of pericytes, aiming to induce further studies of pericytes in andrology.

Objective: To observe the efficacy of the combination of Qilin Pills and levofloxacin in the treatment of asthenospermia accompanied with accessory sex gland infection., Methods: We randomly assigned 80 asthenospermia patients with accessory sex gland infection to groups 1 and 2 of equal number, the former treated with Qilin Pills + levofloxacin, and the latter with levofloxacin only. Qilin Pills were administered at the dose of 6 g tid for 30 days, and levofloxacin at the dose of 0.5 g qd for 20 days. We obtained semen parameters, including the percentage of progressively motile sperm and peroxidase-positive white blood cell (WBC) count, before and after medication, and compared the clinical effects between the two groups., Results: All the patients accomplished the clinical trial. The therapeutic effectiveness rates in improving progressive sperm motility were 60% in group 1 and 17.5% in group 2, with statistically significant differences between the two groups (P < 0.05). As for the peroxidase-positive WBC count in semen, the effectiveness rates were 87.5% and 82.5%, respectively, with no significant differences between the two groups (P > 0.05)., Conclusion: For the treatment of asthenospermia accompanied with accessory sex gland infection, Qilin Pills combined with levofloxacin is evidently better than levofloxacin alone in improving sperm motility, and it has no obvious adverse effects.

Objective: To evaluate the effects of daily medication of low-dose tadalafil on the improvement of endothelial function and erectile hardness in erectile dysfunction (ED) patients., Methods: A total of 60 ED patients and 24 controls were treated with oral tadalafil at 5 mg/d for 6 - 8 weeks, and evaluated by international index of erectile function-5 (IIEF-5), erectile hardness grading scale (EHGS) and brachial artery flow-mediated dilation (FMD) test before and after the treatment. All the data obtained were analyzed by independent-sample and paired-sample t tests, respectively., Results: The treatment and follow-up were accomplished in 51 of the ED cases. Compared with the controls, the ED patients showed significantly lower scores on IIEF-5 (23.6 +/- 1.0 vs 10.3 +/- 4.5, P < 0.01), EHGS (3.7 +/- 0.5 vs 2.0 +/- 0.6, P < 0.01) and FMD (14.1 +/- 2.1 vs 8.1 +/- 1, P < 0.01). Daily medication of tadalafil achieved an effectiveness rate of 96.1% (49/51) in the treatment of the ED patients, and significantly improved their scores on IIEF-5 (16.9 +/- 3.9 vs 10.6 +/- 4.5, P < 0.01), EHGS (2.6 +/- 0.7 vs 2.0 +/- 0.6, P < 0.01) and FMD (9.2 +/- 1.7 vs 8.1 +/- 0.9, P < 0.01), as compared with pretreatment., Conclusion: Long-term daily medication of low-dose tadalafil can significantly improve endothelial function and erectile hardness of ED patients.
