AMH and Infertility: At the patient’s first visit to the infertility clinic, as well as at the time of the most recent IVF treatment, the anti-Müllerian hormone (AMH) level was measured, which has remained essentially stable over the years (AMH: 1.76 ng/mL–1.5 ng/mL; reference range: 1.0–4.0 ng/mL).
