STUDY QUESTION What is the relationship of sex steroid levels with sexual function in women with and without polycystic ovary syndrome (PCOS)? SUMMARY ANSWER Women 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 ALREADY The 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, DURATION This observational prospective case control study with 135 women (68 PCOS, 67 control) was conductedfrom March 2017 until March 2020. PARTICIPANTS/MATERIALS, SETTING, METHODS Heterosexual 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 CHANCE Women 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 CAUTION The 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 FINDINGS Sexual 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 import
