Hyperandrogenemia Induces Trophoblast Ferroptosis and Early Pregnancy Loss in Patients With PCOS via CMA‐Dependent FTH1 Degradation

Advanced Science, Volume 13, Issue 12, 27 February 2026.
In PCOS patients with hyperandrogenemia, decreased ferritin heavy chain 1 (FTH1) causes Fe2⁺ overload and ferroptosis in trophoblasts. Androgens induce FTH1 protein degradation via AR‐LAMP2A‐mediated chaperone‐mediated autophagy pathway, leading to placental development disruption and early pregnancy loss. Metformin mitigates androgen‐induced placental
