Endocrine disruptors are synthetic chemicals, potentially toxic, with the ability to mimic, block or alter the hormones of our body. The problem of the presence of these compounds is exacerbated in the critical exposure windows that are, 72 days before conception for sperm, intrauterine stage and the first 2 years of the newborn. The estrogenic cocktail effect of these endocrine disruptors increases their toxicity.
