Protective Impacts of Quercetin and Echinochrome on Female Fertility and Pregnancy Outcomes in Polycystic Ovary Syndrome in Rats.

Abstract

BACKGROUND: Polycystic ovary syndrome (PCOS) is a universal reproductive, endocrine, and metabolic disorder. It affects 9.2% of women worldwide. Echinochrome (Ech) is the most common dark red pigment of sea urchin shells and possesses high antioxidant and hypoglycemic properties. Quercetin (Quer) is a flavonol widely distributed in plants with high antioxidant properties. Therefore, Ech and Quer as a combined protective therapy were investigated against letrozole and high-fat diet-induced PCOS model in rats. METHODS: Sixty female rats were divided randomly into five groups: Control: received 2% DMSO with a normal diet, PCOS: received letrozole with HFD, Ech: received letrozole and Ech with HFD, Quer: received letrozole and Quer with HFD, Ech + Quer: received letrozole, Ech, and Quer together daily orally for 4 weeks. Half of the rats in each group were sacrificed, and the remaining rats were examined for their ability to mate and fertility. RESULTS: Ech and Quer treatment restored normal levels of lipid and hormonal profiles, oxidative status, kidney and liver functions with a marked amelioration in ovarian, uterine histopathology, and a good evidence in pregnancy analysis. CONCLUSION: Ech and Quer were found to have a potent protective effect against PCOS, minimal side effects, and improved progeny outcomes in rats.
