A previous study showed that the length of the foreskin plays a role in the risk of sexually transmitted infections and chronic prostatitis, which can lead to poor quality of sexual life. Here, the association between foreskin length and sexual dysfunction was evaluated. A total of 5700 participants were recruited from the andrology clinic at The First Affiliated Hospital of University of Science and Technology of China (Hefei, China). Clinical characteristics, including foreskin length, were collected, and sexual function was assessed by the International Index of Erectile Function-5 (IIEF-5) and Premature Ejaculation Diagnostic Tool (PEDT) questionnaires. Men with sexual dysfunction were more likely to have redundant foreskin than men without sexual dysfunction. Among the 2721 erectile dysfunction (ED) patients and 1064 premature ejaculation (PE) patients, 301 (11.1%) ED patients and 135 (12.7%) PE patients had redundant foreskin, respectively. Men in the PE group were more likely to have redundant foreskin than men in the non-PE group ( P = 0.004). Logistic regression analyses revealed that the presence of redundant foreskin was associated with increased odds of moderate/severe ED (adjusted odds ratio [aOR] = 1.31, adjusted P = 0.04), moderate PE (aOR = 1.38, adjusted P = 0.02), and probable PE (aOR = 1.37, adjusted P = 0.03) after adjusting for confounding variables. Our study revealed a positive correlation between the presence of redundant foreskin and the risk of sexual dysfunction, especially in PE patients. Assessment of the length of the foreskin during routine clinical diagnosis may provide information for patients with sexual dysfunction.

This study aimed to investigate the incidence and risk factors for female sexual dysfunction (FSD) in urban and rural China. A prospective cohort study was conducted from February 2014 to January 2016, with follow-up from June to December 2018. Women aged ≽20 years were recruited from urban and rural areas in six provinces of China using a multistage, stratified, cluster sampling method. Sexual function was assessed using the Female Sexual Function Index questionnaire. A total of 16 827 women without sexual dysfunction at baseline participated in this study, 9489 of them (urban, 5321; rural, 4168) who had complete information from baseline to follow-up were included in the final analysis. The rate of follow-up was 68.81%, and the median follow-up time was 4.13 years. The 4-year incidence of FSD was 43.07%, with an incidence density of 12.02 per 100 person-years. In particular, the 4-year incidence and incidence density of FSD were 41.03% and 11.88 per 100 person-years in the urban group and 45.68% and 12.17 per 100 person-years in the rural group. Among women with sexual dysfunction, difficulties in sexual desire, satisfaction, and arousal were the main symptoms. In urban women, the risk factors for FSD included age ≽45 years (adjusted relative risk 1.69, 95% confidence interval 1.57-1.81), hypertension (1.31, 1.14-1.49), previous delivery (1.26, 1.13-1.41), post-menopausal status (1.20, 1.10-1.32), pelvic inflammatory disease (1.13, 1.05-1.21), and multiparity (1.11, 1.03-1.19). In the rural group, the risk factors significantly associated with FSD were age ≽45 years (1.50, 1.40-1.61), previous delivery (1.39, 1.17-1.65), hypertension (1.18, 1.06-1.30), multiparity (1.16, 1.07-1.27), and post-menopausal status (1.15, 1.07-1.23). FSD is a hidden epidemic condition in China, and the development of prevention strategies should consider the distinct risk factors present in rural and urban areas.

This study aimed to estimate the prevalence of and identify the factors influencing female sexual dysfunction (FSD) among Chinese nurses. A cross-sectional survey was conducted from March 2013 to May 2014 among 6 hospitals in Suzhou, China. In total, 2,030 married female nurses were included in the analysis. Data on the sociodemographic, lifestyle, and self-reported health status of the participants were collected, and the participants were asked to complete the Chinese version of the 19-item Female Sexual Function Index (FSFI) questionnaire. In total, 1,035 (50.99%) participants were found to have FSD. Logistic regression analysis showed that increasing age and higher body mass index, lower salary, and poor/very poor self-reported health status were risk factors for FSD; however, regular social activity and physical exercise were protective factors for FSD. The findings of this study suggest that further interventional studies are warranted to study the sexual health among Chinese nurses in detail.

OBJECTIVE: Although nerve-sparing radical surgery (NSRS) is an emerging technique for reducing surgery-related dysfunctions, its efficacy is controversial in patients with cervical cancer. Thus, we performed a meta-analysis to compare clinical outcomes, and urinary, anorectal, and sexual dysfunctions between conventional radical surgery (CRS) and NSRS. METHODS: After searching PubMed, Embase, and the Cochrane Library, two randomized controlled trials, seven prospective and eleven retrospective cohort studies were included with 2,253 patients from January 2000 to February 2014. We performed crude analyses and then conducted subgroup analyses according to study design, quality of study, surgical approach, radicality, and adjustment for potential confounding factors. RESULTS: Crude analyses showed decreases in blood loss, hospital stay, frequency of intraoperative complications, length of the resected vagina, duration of postoperative catheterization (DPC), urinary frequency, and abnormal sensation in NSRS, whereas there were no significant differences in other clinical parameters and dysfunctions between CRS and NSRS. In subgroup analyses, operative time was longer (standardized difference in means, 0.948; 95% confidence interval [CI], 0.642 to 1.253), while intraoperative complications were less common (odds ratio, 0.147; 95% CI, 0.035 to 0.621) in NSRS. Furthermore, subgroup analyses showed that DPC was shorter, urinary incontinence or frequency, and constipation were less frequent in NSRS without adverse effects on survival and sexual functions. CONCLUSION: NSRS may not affect prognosis and sexual dysfunctions in patients with cervical cancer, whereas it may decrease intraoperative complications, and urinary and anorectal dysfunctions despite long operative time and short length of the resected vagina when compared with CRS.

OBJECTIVETo study the changes in sexual function in premenopausal women after renal transplantation.

METHODSForty-two married premenopausal women receiving dialysis therapy for at least 6 months with normal renal function for 6 months after renal transplantation were examined for hormonal profiles and menstrual cycles. The sexual functions of the patients were evaluated using Female Sexual Function Index (FSFI) before and 6 months after the transplantation.

RESULTSBefore renal transplantation, amenorrhea, oligomenorrhea, polymenorrhea, and eumenorrhea were found in 18 cases (42.9%), 10 cases (23.8%), 5 cases (11.9%) and 9 cases (21.4%), as compared to 7 cases (16.7%), 5 cases (11.9%), 6 cases (14.3%) and 24 cases (57.1%) after the transplantation, respectively. Prolactin (PRL), follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels significantly decreased and estradiol (E2) and progesterone (P) significantly increased after renal transplantation (P<0.001). Nineteen patients (45.2%) before and 36 patients (85.7%) after the surgery reported to have an active sexual life (P<0.001). The total incidences of female sexual dysfunction before and after kidney transplantation were 90.5% and 40.5% (P<0.001), respectively. The scores for sexual desire, arousal, lubrication, satisfaction, orgasm, and pain in FSFI were significantly increased after kidney transplantation (P<0.001).

CONCLUSIONSA successful renal transplantation can significantly improve sexual functions in premenopausal women.

OBJECTIVETo investigate the influence of chronic prostatitis on premature ejaculation (PE) and erectile dysfunction (ED) and the correlation of chronic prostatitis with PE and ED.

METHODSWe adopted NIH-CPSI, CISFPE and IIEF-5, interviewed 623 patients with chronic prostatitis, and recorded their scores on the above systems.

RESULTSThe incidence of PE was 39.0% and the rates of the mild, moderate and severe types were 26.2%, 12.0% and 0.8%, respectively. It developed mostly among the younger patients, accounting for 42.9% (103/240), 37.0% (95/257) and 35.7% (45/126) in the 18-30, 30-40 and 40-57 yr age groups, respectively. The incidence of ED was 16.9% and the rates of the mild, moderate and severe types were 14.9%, 1.0% and 1.0%, respectively. It occurred mostly among the older patients, accounting for 13.8% (33/240), 11.3% (29/257) and 34.1% (43/126) in the 18-30, 30-40 and 40-57 yr age groups, respectively. Analyses revealed no significant correlation among the scores on NIH-CPSI, CISFPE and IIEF-5.

CONCLUSIONThere is a high incidence of PE and ED among patients with chronic prostatitis, but without significant correlation between the severity of chronic prostatitis and that of PE and ED.

Premature ejaculation is a common but incompletely understood male sexual dysfunction. Recent years have witnessed fruitful researches on NO in the mechanism of male ejaculation and successful application of selective PDE5 inhibitor in the treatment of male sexual dysfunction. And now the researches on the etiopathogenesis, mechanism, diagnosis and therapy of premature ejaculation have achieved great development. Selective serotonin re-uptake inhibitors (SSRIs) have been widely applied to clinical practice, but with increasing adverse effects. The purpose of the review is to introduce the updated development of the epidemiology, definition, etiopathogenesis, mechanism and therapy of premature ejaculation, and to provide some reference for the diagnosis and management of the problem.

OBJECTIVESTo investigate the prevalence, main manifestation and related factors of sexual dysfunction in male patients with chronic renal insufficiency (CRI).

METHODSA cross-section study was conducted by six hospitals in Sichuan Province. The prevalence and severity of sexual dysfunction were assessed by SCASF microsoft among patients with chronic renal disease. Logistic regression was used to examine and test the association between sexual dysfunction and other medical conditions.

RESULTSThe prevalence of sexual dysfunction was wider in patients with CRI than in those without. The main manifestations in male patients were decreased libido, erectile dysfunction and premature ejaculation. Stratified analysis in uremia showed that the prevalence and severity of sexual dysfunction were similar between patients on haemodialysis(HD) and those on peritoneal dialysis(PD). The patients receiving no replacement treatment suffered more decreased libido and performance anxiety than dialyzed patients (HD and PD) and transplantation patients(Tx). The patients receiving no replacement treatment and dialysis suffered more erectile dysfunction than Tx men. A multivariable analysis demonstrated that the duration, creatinine clearance(Ccr), parathyroid hormone (PTH), albumin(Alb) were not associated with sexual dysfunction. The use of beta-blocker, anemia and depression were risky factors for decreased libido, and increasing age was a risky factor for erectile dysfunction. The use of angiotensin-converting-enzyme inhibitor(ACEI)/angiotention receptor antagonist (ARB) and recombinant human erythropoietin(r-HuEpo) were protective factors for erectile dysfunction.

CONCLUSIONSThe main manifestations of sexual dysfunction in male patients with CRI are decreased libido, erectile dysfunction and premature ejaculation. The replacement therapy, especially transplantation, can decrease the prevalence or severity of sexual dysfunction. The genesis of sexual dysfunction is multifactorial, including age, physiological factors, psychological factors and medical conditions.

OBJECTIVETo investigate the prevalence of chronic prostatitis in men with premature ejaculation.

METHODSThe segmented urine specimens before and after prostatic massage and the expressed prostatic secretion specimens from 106 patients with premature ejaculation and 38 controls were evaluated by microscopic and/or bacteriological studies. The prevalence of premature ejaculation was also investigated in 120 patients with chronic prostatitis.

RESULTSProstatic inflammation was found in 46.2% and chronic bacterial prostatitis in 34.7% of the subjects with premature ejaculation, respectively. Compared with the controls, the findings were statistically significant (P < 0.05). The prevalence of premature ejaculation in the patients with chronic prostatitis was 47.5% (57/120).

CONCLUSIONSChronic prostatic inflammation may play a role in the pathogenesis of some cases of premature ejaculation and it is important to give a careful examination of the prostate before initiating any therapy for premature ejaculation.
