AMH and endometriosis: Recently published data from the Nurses’ Health Study II (NHS II) identified women with laparoscopically confirmed endometriosis (n = 119) to have 29.6% lower AMH levels (95% CI: −45.4, −9.2) compared to those without endometriosis (n = 1842), a finding that did not vary based on parity or infertility history [26].
