A recent study by Mimouni et al. shows that late gestation exposure to anti-Müllerian hormone (AMH) results in transgenerational transmission of a polycystic ovary syndrome (PCOS)-like phenotype in mice. Altered DNA methylation underlies transmission and was also observed in women with PCOS. Epigenetics-based therapy reversed some PCOS-like phenotypic traits when applied to F3 female mice.
Keywords: anti-Müllerian hormone; epigenetics; germ cells; in utero environment; maternal androgen excess; transgenerational transmission.
