Popis: Introduction: An endocrine-disrupting chemical (EDC) is defined as "an exogenous chemical or a mixture of chemicals that interfere with any aspect of the hormonal action". Endocrine systems are a physiological interface with the environment and genetic-environmental interactions are disrupted by EDCs. Today, there are almost 1000 chemicals reported to have endocrine effects: the prevalence of EDC in our environment and in our bodies represents a major global health challenge. This review gathers the studies that have investigated the correlations between exposure to EDC and pathologies of the female reproductive system and fetal development. Methods: A PubMed research was conducted using the keywords, their variants, and their combinations (BPA, DES, MXC, pesticides, phthalates, plasticizers, PCBs, dioxins, ovaries, oocytes, ovaries, fallopian tubes, follicles, vagina, uterus, fibroids, fertility, infertility, puberty, polycystic ovary syndrome, premature ovarian failure, birth, preterm birth, birth outcome, steroid, hormone, female, girl and menopause). Results: The endocrine system plays a central role in all vertebrates and regulates critical biological functions such as metabolism, development, reproduction, and behavior. Epidemiological studies link EDCs with reproductive effects, neuro-behavioral and neurodevelopment alterations, metabolic syndrome, bone disorders, immune disorders, and cancers in humans. Human investigations confirm the results of the studies carried out on animal showing associations with many additional effects on health, including asthma, learning and behavior problems, premature puberty, infertility, breast and prostate cancer, Parkinson's disease, obesity and other diseases. Conclusions: It is important to undertake research with follow-up methodologies and/or longitudinal studies to detect the extent of exposure of pregnant women to EDCs and halogenated substances and the effects of such exposure on brain development. A future research hypothesis may consider the effect that these substances have on neuro-development and, more specifically, how EDCs are involved in pathogenic disorders such as autism spectrum disorders (ASD). In addition, a scientific study could be performed on the correlations between this type of substance and the inconveniences found in the field of executive frontal functions.
