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.

OBJECTIVETo investigate the prevalence of hyposexuality, erectile dysfunction (ED) and defective ejaculation (DE) in the old and middle-aged males in Pingliang area.

METHODSThis investigation included 1 539 men aged > or = 50 years from 6 urban districts and 20 villages in the suburbs of Pingliang City, Gansu Province. We recorded and analyzed their scores on IIEF-5 and Brief Male Sexual Function Inventory for Urology (O'Leary 1995).

RESULTSA total of 1 230 subjects met the investigation criteria. They averaged 62.5 +/- 9.6 years of age (range 50-89 years), and were divided into four age groups: 50-59, 60-69, 70-79 and > or = 80 years. The mean scores on IIEF-5 were 0-25 (9.4 +/- 8.6), sexual desire 0-8 (2.3 +/- 2.1), and ejaculation 0-8 (3.6 +/- 3.0). Hyposexuality, ED and DE were defined as sexual desire score < or = 2, IIEF-5 score = 0-21, and ejaculation score < or = 2, respectively. Based on these criteria, the incidence rates of hyposexuality, ED and DE were 57.96%, 92.27% and 36.91%, respectively, with statistically significant differences among different age groups (P < 0.01).

CONCLUSIONThe prevalence of ED, hyposexuality and DE, particularly the incidence of ED, is positively correlated with the increase of age in the old and middle-aged males in Pingliang area.

OBJECTIVEFemale sexual dysfunction (FSD) is a common problem affecting women's quality of life. However, reports are rarely seen on sexual problems in Chinese women. This study is to investigate the prevalence of FSD among urban Chinese women in Nanjing and offer some evidence for the establishment of preventative measures for FSD in China.

METHODSA cross-sectional hospital-based survey was conducted in Nanjing, China between August 2008 and March 2009. The sexual function of 609 women aged 20 -56 years from the urban area of Nanjing were investigated using the Female Sexual Function Index (FSFI). The total FSFI score of < 25 was used as the diagnostic criterion for FSD.

RESULTSThe total FSFI score was 24.21 +/- 4.40 in this group of women, and it decreased with the increase of age. The overall prevalence of FSD was 56.8%, and it increased with the increase of age, 47.1%, 57.0%, 75.0% and 90.3% in the < 29 yr, 30 - 39 yr, 40 - 49 yr and > or = 50 yr groups, respectively. The most common problems were low sexual satisfaction (43.2%) and orgasm disorder (41.7%), followed by sexual pain (40.2%), hyposexuality (35.1%), vaginal dryness (31.4%) and sexual arousal disorder (29.6%).

CONCLUSIONFSD is a common problem among urban Chinese women in Nanjing, and the most common sexual problems are low sexual satisfaction and orgasm disorder.

Female sexual dysfunction (FSD) is an age-related progressive disease and may affect up to half of adult women, but it has failed to receive due attention for a long time. Hypertension is a common and frequently encountered disease, and female sexual dysfunction is closely related to hypertension and antihypertensive drugs. Hypertension-related atherosclerosis, endothelial disorder and antihypertensive drugs are important risk factors for female sexual function. This article reviews the mechanisms of hypertension-induced FSD and advances in their studies.

Sexual dysfunction affects both men and women, involving organic disorders, psychological problems, or both. Overall, the state of our knowledge is less advanced regarding female sexual physiology in comparison with male sexual function. Female sexual dysfunction has received little clinical and basic research attention and remains a largely untapped field in medicine. The epidemiology of female sexual dysfunction is poorly understood because relatively few studies have been done in community settings. In the United States, female sexual dysfunction has been estimated to affect 40% of women in the general population. Among the elderly, however, it has been reported that up to 87% of women complain of sexual dissatisfaction. Several studies have shown that the prevalence of female sexual arousal disorders correlates significantly with increasing age. These studies have shown that sexual arousal and frequency of coitus in the female decreases with increasing age. The pathophysiology of female sexual dysfunction appears more complex than that of males, involving multidimensional hormonal, neurological, vascular, psychological, and interpersonal aspects. Organic female sexual disorders may include a wide variety of vascular, neural, or neurovascular factors that lead to problems with libido, lubrication, and orgasm. However, the precise etiology and mechanistic pathways of age-related female sexual arousal disorders are yet to be determined. In the past two decades, some advances have been made in exploring the basic hemodynamics and neuroregulation of female sexual function and dysfunction in both animal models and in human studies. In this review, we summarize neural regulation of sexual function and neurological causes of sexual dysfunction in women.

OBJECTIVETo investigate the factors related to sexual dysfunction among breast cancer patients so as to improve the prevention and treatment of the disorder as well as the life quality of the patients.

METHODSSixty-five breast cancer patients during the rehabilitation period were interviewed by questionnaire on the sexual function before and after treatment.

RESULTSAge and perception of sex were two important factors for the significant difference in the rate of sexual dysfunction among the patients. In the groups of 45-55 and 56-65 years, the rates of sexual dysfunction were 66.7% and 73.9%, respectively. Compared with the < 45-year group (33.3%), the findings were statistically significant (P < 0.01), and the difference was statistically significant between the incorrect perception group (70.3%) and the correct one (47.6%) (P < 0.05). Of all the factors analyzed in the research, the stage of cancer, treatment methods, vaginal dryness, decreased libido, dyspareunia and sex perception had significant correlation with newly developed sexual dysfunction (P < 0.05).

CONCLUSIONThe stage of cancer, treatment methods, sex perception, vaginal dryness et al had significant correlation with sexual dysfunction of breast cancer patients after treatment. To treat and prevent sexual dysfunction among breast cancer patients, oncology professionals should initiate communication about sexual difficulties, perform comprehensive assessments, and educate and counsel patients about the management of these difficulties.

OBJECTIVETo investigate the prevalence of sexual dysfunction in chronic prostatitis patients and its relation with patients' age and the course of disease.

METHODSQuestionnaire surveys were completed by 2 000 subjects who met the criteria for chronic prostatitis after clinical examination and expressed prostatic secretion analysis. Included in the questionnaire were: (1) age, height, weight, occupation, course of disease and treatment received; (2) NIH-CPSI; and (3) IIEF-5.

RESULTSThe prevalence of sexual dysfunction in patients with chronic prostatitis was 49.0% : 26.2% of the subjects with premature ejaculation, 15.0% with erectile dysfunction and 7.7% with both premature ejaculation and erectile dysfunction.

CONCLUSIONThe prevalence of sexual dysfunction in patients with chronic prostatitis is high, which is negatively correlated with both the age of the patients (P < 0.001) and the course of the disease (P < 0.001).

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.
