The xenoendocrine disruptors are environmental polluters that alter the hormonal physiology of animals and humans through different mechanisms. This revision was made with the purpose of gathering recent information on chemical groups to which this effect have been demonstrated, the way they do it and the consequences in males and females in different stages of their life. The study shows that, in spite of the great quantity of experimental and epidemic studies that have been developed, they are still hypothesis waiting to be demonstrated and many compounds to be evaluated.
