We performed immunolabeling for laminin, an extracellular matrix glycoprotein that labels the surface of ovarian follicular structures,54 and anti-Müllerian hormone (AMH), which participates in ovarian folliculogenesis and whose intraovarian and circulating levels are higher in women with PCOS as compared to normo-ovulatory women.35 This evidence concerns the gene AMH and polycystic ovary syndrome.
