Protective Effects of Melatonin Against Metabolic and Reproductive Disturbances in Polycystic Ovary Syndrome in Rats

The document presents a study that explored the therapeutic effects of melatonin on polycystic ovary syndrome (PCOS) in rats. The rats with PCOS showed significant improvements when treated with melatonin at doses of 1 mg/kg and 2 mg/kg. The treatment led to reductions in body weight, BMI, intraabdominal fat, insulin levels, and C-reactive protein, as well as improved lipid profiles and glucose tolerance. Histopathological analysis revealed fewer cystic follicles and neoplastic endometrial glands, and reduced adipocyte hypertrophy. Melatonin's effects were similar to those of metformin, a common PCOS treatment. The study included six rats in the control group and eight in the treatment groups, suggesting that melatonin may be beneficial for treating PCOS, but clinical studies are needed to confirm these findings.
