This study evaluated the effects of melatonin supplementation in 56 women with polycystic ovary syndrome (PCOS) over 12 weeks. Participants were divided into two groups, with one receiving 5 mg of melatonin and the other a placebo. Results showed that melatonin significantly reduced hirsutism, serum total testosterone, high-sensitivity C-reactive protein (hs-CRP), and plasma malondialdehyde (MDA) levels. It also increased plasma total antioxidant capacity (TAC) and total glutathione (GSH) levels. Additionally, melatonin downregulated the gene expression of interleukin-1 (IL-1) and tumor necrosis factor alpha (TNF-α). Overall, melatonin administration improved hormonal, inflammatory, and oxidative stress parameters in women with PCOS.
