ABSTRACT
Purpose:
The aim of the current study was to evaluate the effect of melatonin administration on clinical, hormonal, inflammatory, and genetic parameters in women with polycystic ovarian syndrome (PCOS).Methods:
The present randomized, double-blinded, placebo-controlled clinical trial was conducted among 56 patients with PCOS, aged 18-40 years old. Subjects were randomly allocated to take either 5 mg melatonin supplements (n = 28) or placebo (n = 28) twice a day for 12 weeks.Results:
Melatonin administration significantly reduced hirsutism (ß -0.47; 95% CI, -0.86, -0.09; P = 0.01), serum total testosterone (ß -0.11 ng/mL; 95% CI, -0.21, -0.02; P = 0.01), high-sensitivity C-reactive protein (hs-CRP) (ß -0.61 mg/L; 95% CI, -0.95, -0.26; P = 0.001), and plasma malondialdehyde (MDA) levels (ß -0.25 µmol/L; 95% CI, -0.38, -0.11; P < 0.001), and significantly increased plasma total antioxidant capacity (TAC) levels (ß 106.07 mmol/L; 95% CI, 62.87, 149.28; P < 0.001) and total glutathione (GSH) (ß 81.05 µmol/L; 95% CI, 36.08, 126.03; P = 0.001) compared with the placebo. Moreover, melatonin supplementation downregulated gene expression of interleukin-1 (IL-1) (P = 0.03) and tumor necrosis factor alpha (TNF-α) (P = 0.01) compared with the placebo.Conclusions:
Overall, melatonin administration for 12 weeks to women with PCOS significantly reduced hirsutism, total testosterone, hs-CRP, and MDA, while increasing TAC and GSH levels. In addition, melatonin administration reduced gene expression of IL-1 and TNF-α.
