Synergistic Amelioration of Letrozole-induced Polycystic Ovary Syndrome in Rats: A Therapeutic Approach with Apple Cider Vinegar and Metformin Combination
Abstract
The present study was conducted to evaluate the combination effect of apple cider vinegar (ACV) and metformin against letrozole-induced polycystic ovary syndrome (PCOS). Female Wistar rats were administered letrozole (1 mg/kg/day, p.o) for 21 days, except for the control group of animals. On the 22nd day, PCOS-induced animals were segregated into 4 groups and administered with CMC, ACV, metformin, and a combination of ACV and metformin, respectively. The treatments were continued for 15 days, and on the 36th day, all the animals were sacrificed for biochemical (blood glucose, lipid profile), hormonal (sex hormones and adiponectin), and pro-inflammatory mediator estimations in blood samples. The ovarian tissue samples were used for oxidative stress parameters and histological alterations. The PCOS control animals showed a significant alteration in the estrous cycle. The administration of letrozole resulted in the alteration of hormonal balance and elevation of body weights, glycemic state, lipid profile, pro-inflammatory mediators in serum, and oxidative stress in ovarian samples. Individual treatment groups and combination treatment groups reversed the letrozole-induced alterations in PCOS animals, and more promising results were observed with combination therapy than with individual treatment groups. Further, the therapeutic potential of the combination treatment group was also confirmed by the histological observations in the ovarian samples. The study showed that the…
