“…This process is due to the presence of the Y chromosome containing SRY gene, responsible for the testicular cell line support, resulting in the differentiation of precursor Sertoli cells and secretion of antiMüllerian hormone (Rey 2005;Blaschko et al 2012), which induces regression of Müllerian duct. This hormone continues to be produced until puberty, and then decreases until reaching residual values (Okay 2003). The cell line of testicular interstice differentiates into Leydig cells, which produce testosterone, promoting the development of Wolff ducts and their subsequent derivative organs (Vainio et al 1999;Domenice et al 2002;Arnold 2009;Blaschko et al 2012).…”
