Sexual Function in Chinese Women with Polycystic Ovary Syndrome and Correlation with Clinical and Biochemical Characteristics.

To investigate sexual function in Chinese women with polycystic ovary syndrome (PCOS) and to explore the correlation with clinical and biochemical characteristics. A cross-sectional study was designed in 1000 PCOS women, aged 18-45 years, via the Chinese version of Female Sexual Function Index (FSFI) evaluating sexual function, with additional questions possibly related to sexual life. Clinical and biochemical characteristics likely to affect sexual function were determined, including anthropometric indicators, serum levels of hormones, luteinizing hormone to follicle-stimulating hormone ratio (LH/FSH ratio), prolactin (PRL), total testosterone (TT), free androgen index (FAI), sex-hormone-binding globulin (SHBG), glucose, and lipid metabolism indicators. Nine hundred ten PCOS women participated in the study, 685 patients were included after screening, and 211 were suitable to detect correlations of clinical and biochemical characteristics with sex function parameters. The mean total FSFI score was 24.19 ± 2.8; 79.56% of the women were at risk of female sexual dysfunction (FSD). Women doing regular aerobic exercise and use of contraception had higher FSFI scores, while those with a desire to conceive and clinical signs of hyperandrogenism had lower FSFI scores. There were negative associations of FSFI scores with age and body fat distribution. No significant associations between FSFI scores and hormonal factors (surprisingly including SHBG) were found, except for total testosterone and satisfaction (OR = 0.976, p = 0.002). HOMA-IR was significantly related to reduced desire score (OR = 0.914, p = 0.004) and lubrication score (OR = 0.964, p = 0.044). PCOS was associated with a high risk of FSD (defined according to FSFI) in about 80% of the women in our study, and clinical characteristics play a more important role.
