Abstract

Purpose: Polycystic ovarian syndrome (PCOS) is the heightened ovarian dysfunction associated with excessive androgen production, manifesting with hirsutism, abnormal menstrual cycle, and polycystic ovaries. In this systematic review and meta-analysis, the effect of resveratrol on laboratory parameters of PCOS women will be assessed.

Methods: An electronic search via PubMed, Cochrane Library, and Scopus was performed up to February 2023 for randomized controlled trials conforming to our pre-specified outcomes. A random-effects model was utilized, with cohorts compared using mean differences.

Results: Three randomized controlled trials (RCTs) were included, reporting 84 patients receiving resveratrol, and 85 patients receiving placebo. It was observed that resveratrol significantly improved prolactin levels (P = 0.02), acne scores (P = 0.008), and total cholesterol (P = 0.02). However, there were no significant improvements observed with respect to total testosterone, follicle stimulating hormone (FSH), lutenizing hormone (LH), body mass index (BMI), hirsutism scores, triglycerides, high-density lipoprotein (HDL), and low-density lipoprotein (LDL).

Conclusion: As per the results of our analysis, resveratrol demonstrates mild therapeutic potential for the sufferers of PCOS, and cannot replace the current established treatment guidelines. However, further comprehensive RCTs are required in order to assess the efficacy in long-term dosing and the safety profile of the use of resveratrol.
