Abstract
Polycystic ovary syndrome (PCOS) is a common endocrinological disorder in women within reproductive age. It is characterized by hyperandrogenism and chronic anovulation it has bad impact on their sexual function.
Obesity is not a part of the phenotype in many parts of the world. Obesity is likely not a cause of PCOS, however, obesity does exacerbate many aspects of the PCOS phenotype which related to clinical features such as hirsutism, menstrual abnormalities and anovulation.
This study aimed to assess the sexual function of overweight compared to normal weight women with PCOS using a validated questionnaire, the Female Sexual Function Index (FSFI), as a measurement tool.
This was a cross-sectional study conducted in 120 married women who are subdivided into four groups:
• group I: obese PCO (N=30) with a BMI > 25 kg/m2,
• group II: non-obese PCO (N=30) with a BMI <25 kg/m2,
• group III: obese non-PCO (N=30) with a BMI > 25 kg/m2,
• group IV: non-obese non-PCO (N=30) with a BMI < 25 kg/m2
All participants will be subjected to full medical history, physical examination, laboratory tests (RBS, FSH, LH, oestradiol (E2), prolactin (PRL), and free testosterone) and sexual function assessment by FSFI questionnaire (total FSFI score cutoff of 26 will be used to distinguish case with and without female sexual dysfunction) .
After statistical analysis, the results were as follows:
PCOS women had significantly lower fertility rates and were more likely to have significantly irregular menses (p<O.05). cases also had significantly lower parity (p<O.05). The menstrual interval of cases was much longer than that of controls (p<O.05).
According to laboratory results PCOS patients had significantly higher LH and free testosterone levels (p<O.05). However, other hormones did not show any statistically significant differences between both groups. According to FSFI there were no statistically significant difference between both groups regarding total FSFI or any of its domains. Serum testosterone level in PCOS patients showed significant positive correlation with arousal and orgasm domains.
