Anti-Mullerian hormone is linked to the type of early pregnancy loss in idiopathic recurrent miscarriage: a retrospective cohort study

We correlated Anti-Mullerian hormone (AMH) levels and other parameters for ovarian reserve to the gestational age at the time of pregnancy loss in women with idiopathic recurrent miscarriage. In a retrospective study, 79 patients had suffered a total of 266 miscarriages. When comparing women with an “unembryonic” to those with an “embryonic” most recent miscarriage, there was no difference in median age (36.3 years, IQR 31.6–40.1 versus 34.2 years, IQR 29.9–38.0; p = 0.303) but in median AMH levels (0.7, IQR 0.2–18, versus median 1.8, IQR 1.3–3.3, respectively, p = 0.044) and in the rate of patients with an AMH ≤ 1 ng/mL (23/37, 62.2%, versus 8/42, 19%; p < 0.001). Thus, AMH might add to the diagnostic process in recurrent miscarriage in the future.
