Endocrine disrupting substance, BPA, PCOSAbstract
Polycystic ovarian syndrome (PCOS) is heterogeneous endocrine disorder in females manifesting reproductive dysfunction and metabolic abnormalities. Endocrinopathy in the form of hyperandrogenism leading to alteration in clinical phenotype and fertility seen. Atherogenic dyslipidaemia and insulin resistance as a result of metabolic disturbance also encountered. Recent years, endocrine disrupting chemicals (EDCs) are widely studied and linked for their alleged role in the development of PCOS. EDCs like bisphenol A (BPA), Phthalate, methoxychlor and chlorpyrifos which are present in many industrial as well as daily use products poses risk of development of various diseases. This review discusses the role of EDCS specially BPA in the pathogenesis of PCOS with study of interest identified and extracted from databases like Pub Med and Google scholars using MeSH keywords. BPA has estrogenic property and binds to oestrogen receptors α and β. Stimulation of ovarian theca cells and dysregulation of steroid biosynthesis leads to androgen overproduction. It stimulates GnRH Pulse generator, decreasing the level of LH hence fertility is affected. BPA also interact with adipose tissue receptors and causes differentiation, lipid deposition and inhibition of adiponectin. Its serum and urinary levels are found to be elevated in PCOS patient. In animal studies, it is found that BPA exposure causes impaired folliculogenesis, insulin resistance and DNA methylation. EDC exposure, especially BPA which is an integral constituent of many industrial and daily use items may cause PCOS possibly by altering androgen synthesis, adipocyte stimulation and epigenetic modification.
