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

Abstract

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.
