Although placental aromatase usually prevents the latter from being passed into fetal circulation, the Giacobini group recently proposed a mechanism wherein maternal AMH, which is elevated in pregnant people with PCOS,27 stimulates luteinizing hormone (LH)‐dependent androgen secretion in the maternal circulation, which is transmitted to the fetus through the downregulation of placental aromatase activity.27 Here, PLOD1 is linked to polycystic ovary syndrome.
