An altered in utero milieu, such as excessive androgen (Abbott et al., 2002; Franks and Berga, 2012; Padmanabhan and Veiga-Lopez, 2013; Risal et al., 2019; Walters et al., 2018), or elevated levels of anti-Müllerian hormone (AMH) exposure (Tata et al., 2018), may be in part responsible for the development of PCOS. Here, AMH is linked to polycystic ovary syndrome.
