OBJECTIVE: The issue of female sexual function is often overlooked in women with endometriosis, especially in mainland China. The objectives of this study were to estimate the prevalence and associated factors of female sexual dysfunction in endometriosis in China.
METHODS: This cross-sectional study was conducted at a referral university hospital in Beijing, Peoples Republic of China from July 2011 to April 2012. Women were recruited among inpatients scheduled for laparoscopic surgery based on signs and symptoms suggestive of endometriosis. Before laparoscopy, a semi-structured questionnaire was used to collect demographic data and disease characteristics. The simplified Chinese version of the Female Sexual Function Index was used to assess sexual function.
RESULTS: A total of 111 consecutive women with histologically confirmed endometriosis were enrolled in this study. The prevalence of female sexual dysfunction was 73% for those with endometriosis. Univariable analysis identified three potential predictors of female sexual dysfunction: pelvic pain intensity; deep infiltrating endometriosis status; and revised American Society for Reproductive Medicine stages. Multivariable analysis showed that moderate-to-severe pelvic pain (adjusted odds ratio [OR] 3.4, 95% confidence interval [CI] 1.3–8.8) and revised American Society for Reproductive Medicine stage III or IV (adjusted OR 4.4, 95% CI 1.3–15.5) were associated with increased risk of having female sexual dysfunction.
CONCLUSION: Female sexual dysfunction is common in women with endometriosis, especially for those with severe pelvic pain and advanced stages of endometriosis.
