Nonalcoholic fatty liver disease and female sexual dysfunction in Egyptian premenopausal women: is there a link between metabolic syndrome and sexual function?

Background: Nonalcoholic fatty liver disease (NAFLD) is a major health problem with a paucity of available information about its impact on female sexual dysfunction (FSD).

Aim: We aimed to study the association between NAFLD and FSD in Egyptian premenopausal women.

Methods: Sexually active married premenopausal women who visited our NAFLD outpatient screening clinic (2019 to 2022) were divided into NAFLD and non-NAFLD (control) groups based on liver ultrasound and fatty liver index data. All participants completed the Arabic Female Sexual Function Index (ArFSFI) questionnaire. The resulting data were used to calculate the domains and total scores. FSD is then graded as follows: no FSD (≥28.2), minimal (21.7-28.1), mild (14.5-21.6), moderate (7.3-14.4), and severe (≤7.2).

Outcomes: We determined the proportions of patients and controls for whom ArFSFI scores indicated dissatisfaction with their sexual lives.

Results: Of 995 women participants whose FSFI scores were available, NAFLD was detected in 487 (48.9%) and absent in 508 (51.1%). The two groups were comparable in age, socioeconomic level, residence, and history of female genital cutting. The NAFLD patients had significantly much lower mean scores for the sexual arousal, lubrication, orgasm, satisfaction, and pain domains of the FSFI (P < .001 for all), while no statistical difference was noticed in the desire domain for NAFLD patients compared with the controls. NAFLD women had significantly lower mean total FSFI scores than the controls (mean [SD] 16.7 [6.8] vs 21.7 [5.1], respectively; P < .001) with higher rates of FSD (98.5% vs 82.1%; P < .001, respectively). Most NAFLD women had higher FSD grades than controls (%): no FSD (1.5, 17.9), minimal (20.6, 51.8), mild (42.5, 38.8), moderate (26.2, 9.4), and severe (10.7, none), respectively.

Clinical Implications: Given the high prevalence of FSD in patients with NAFLD, greater attention to FSF could improve the quality of life in patients with NAFLD.

Strengths And Limitations: This study was limited by the lack of testing of sex hormones and some other important factors that were not tested (eg, age, socioeconomic level, residence, and female genital cutting), as these characteristics were previously matched. Strengths of the study include the large study size, to our knowledge the largest to date to investigate the possible link between FSD and NAFLD in premenopausal women, together with the inclusion of the detailed version of the validated ArFSFI.

Conclusions: In Egyptian premenopausal women, NAFLD could harm their sexual function.
