On the basis of experimental, epidemiological and clinical data, it has been included in the testicular dysgenesis syndrome and believed to be influenced, together with genetic and anatomic factors, by maternal exposure to endocrine disrupting chemicals (EDCs). Here we analyze how EDCs may interfere with the control of testicular descent, which is regulated by two Leydig cell hormones, testosterone and insulin like peptide 3 (INSL3).
