Abstract
Background: Women with advanced chronic kidney disease (CKD) encounter reproductive health challenges, including reduced fertility, menstrual irregularity, and sexual dysfunction. This study examined changes in sex hormones in patients with CKD, their correlation with sexual function, and changes after transplant. Methods: This study recruited women aged 18–51 years with CKD stages 3b-5 from outpatient clinics and dialysis units. Exclusion criteria included active pregnancy, menopause, prior hysterectomy/bilateral oophorectomy, or use of hormonal contraceptives/therapy. Data were collected at enrollment and at 6 months post-transplant. Results: Thirty-eight subjects met eligibility criteria and enrolled in the trial (8 in CKD stage 3b, 10 in CKD stage 4, and 20 in CKD stage 5/5D). Sexual dysfunction (25/38, 65.8%), defined as total female sexual function index score < 26.55, and menstrual irregularities (17/38, 44.7%) were common, with abnormal elevation of luteinizing hormone present in the follicular phase in the majority of patients. There was a significant negative association between total female sexual function index score and prolactin (β = -0.26, P = 0.03) and dehydroepiandrosterone sulfate (β = -0.07, P = 0.01) after adjusting for age. After transplant, there was also a significant improvement in both prolactin and dehydroepiandrosterone sulfate levels, although sexual dysfunction persisted. Conclusions: This study highlights the complex interplay between advanced CKD, reproductive endocrinology, and sexual health. Significant hormonal dysregulation and associated reproductive challenges were observed. The prominent role of dehydroepiandrosterone sulfate in sexual dysfunction among women with CKD requires further study.
