Sexual dysfunction in women with PCOS:a case control study

STUDY QUESTIONWhat is the relationship of sex steroid levels with sexual function in women with and without polycystic ovary syndrome (PCOS)?SUMMARY ANSWERWomen with PCOS reported more sexual dysfunction and more sexual distress compared to those without PCOS, but only few and weak associations between androgen levels and sexual function were observed.WHAT IS KNOWN ALREADYThe literature shows that women with PCOS report lower levels of sexual function and sexual satisfactionand more sexual distress. Contributing factors seem to be obesity, alopecia, hirsutism, acne, infertility, anxiety, depression, and low self-esteem. In women with PCOS clinical and/or biochemical hyperandrogenism is common; its relationship with sexualfunction is, however, inconclusive.STUDY DESIGN, SIZE, DURATIONThis observational prospective case control study with 135 women (68 PCOS, 67 control) was conductedfrom March 2017 until March 2020.PARTICIPANTS/MATERIALS, SETTING, METHODSHeterosexual women with and without PCOS, aged 18–40 years, in a steady relationshipand without any comorbidities, underwent an extensive medical and endocrine screening using liquid chromatography-tandem mass spectrometry and validated sexual function questionnaires.MAIN RESULTS AND THE ROLE OF CHANCEWomen with PCOS reported significantly lower sexual function (Female Sexual Function Index (FSFI) P < 0.001, partial η2 = 0.104), higher levels of sexual distress (Female Sexual Distress Scale-Revised P < 0.001, partial η2 = 0.090), and they more often complied with the definition of sexual dysfunction (41.2% vs 11.9%, P < 0.001, Phi V = 0.331) and clinical sexual distress (51.5% vs 19.4%, P < 0.001, Phi V = 0.335). Regression analysis adjusted for confounders showed only few and weak associations between androgen levels and sexual function, with each model explaining a maximum of 15% sexual function. Following significant Group × Hormone interactions, analyses for both groups separately showed no significant associations in the PCOS group. The control group showed only weak negative associations between testosterone and FSFI pain (β = −6.022, P = 0.044, Adj R2 = 0.050), between FAI and FSFI orgasm (β = −3.360, P = 0.023, Adj R2 = 0.049) and between androstenedione and clinical sexual distress (β = −7.293, P = 0.036, exp(β) = 0.001).LIMITATIONS, REASONS FOR CAUTIONThe focus of the study on sexual functioning potentially creates selection bias. Possibly women with more severe sexual disturbances did or did not choose to participate. Differences between women with PCOS and controls in relationship duration and hormonal contraceptive use might have skewed the sexual function outcomes.WIDER IMPLICATIONS OF THE FINDINGSSexual function is impaired in women with PCOS. However, endocrine perturbations seem to have minimal direct impact on sexual function. Addressing sexuality and offering psychosexual counseling is important in the clinical care for women with PCOS
