Chemical Induce Polycystic Ovarian Syndrome-Preclinical Animal Models

Abstract

Polycystic ovarian syndrome is a complex endocrine disturbance that leads to hyperandrogenism, disruption in the functioning of the Hypothalamic-Pituitary-Ovary (HPO) axis and multiple cysts in ovaries. To understand and study different treatment approaches of polycystic ovarian syndrome, there are several chemical-induced animal models available that mimic polycystic ovarian syndrome. These animal models are designed to closely resemble the characteristic symptoms. Polycystic Ovarian Syndrome’s key characteristics are changes in gonadotropin and sex steroid hormone, ovarian morphology, and metabolic characteristics. Direct hormone-regulated animal models are frequently utilized to study PCOS. Rodent animal model is often used which aims to replicate the key feature of human PCOS. Various endocrine-disrupting chemicals also makes a major role in the development of PCOS. In order to bridge the gap between basic research and clinical application in the field of PCOS, PCOS-induced models are essential tools for improving our understanding of the illness and evaluating innovative therapies. The review discusses various animal models used to induced PCOS by various inducers such as aromatase inhibitor inducer (letrozole), androgen excess inducer (dihydrotestosterone, dehydroepiandrosterone, testosterone), estrogen-induced (estradiol valerate), antiprogesterone (mifepristone), monosodium-L-glutamate, bisphenol-A and tributyltin chloride. This article contributed to underlying the current understanding and provides you a complete review that overall covers various aspects, including the impact of chemical-induced models, which also includes changes in the morphology of ovaries, gonadotropin as well as, and alterations in the level of various sex steroid hormone profile. Additionally it explores the metabolic abnormalities caused by various chemical-inducers used to induce PCOS in animal. The objective of this review is to provide a comprehensive review about various chemical inducers which are responsible for the development of PCOS.
