Exposure to Modern, Widespread Environmental Endocrine Disrupting Chemicals and Their Effect on the Reproductive Potential of Women: An Overview of Current Epidemiological Evidence

Anetta Karwacka et al. Hum Fertil (Camb). .

Abstract

Growing evidence indicates that exposure to widespread, environmental contaminants called endocrine disruptors (EDCs) negatively affects animal and human reproductive health and has been linked to several diseases including infertility. This review aims to evaluate the impact of environmental exposure to endocrine disrupting chemicals [phthalates, parabens, triclosan, bisphenol A (BPA), organochlorine (PCBs) and perfluorinated (PFCs) compounds] on the reproductive potential among women, by reviewing most recently published literature. Epidemiological studies focusing on EDCs exposure and reproductive potential among women for the last 16 years were identified by a search of the PUBMED, MEDLINE, EBSCO and TOXNET literature databases. The results of the presented studies show that exposure to EDCs impacts the reproductive potential in women, measured by ovarian reserve and by assisted reproductive technology outcomes. Exposure to environmental endocrine disrupting chemicals decrease: (i) oestradiol levels (BPA); (ii) anti-Müllerian hormone concentrations (PCBs); (iii) antral follicle count (BPA, parabens, phthalates); (iv) oocyte quality (BPA, triclosan, phthalates, PCBs); (v) fertilization rate (PFCs, PCBs); (vi) implantation (BPA, phthalates, PCBs); (vii) embryo quality (triclosan, PCBs, BPA); (viii) rate of clinical pregnancy and live births (parabens, phthalates). The studies were mostly well-designed and used prospective cohorts with the exposure assessment based on the biomarker of exposure. Considering the suggested health effects, more epidemiological data is urgently needed to confirm the presented findings.
