Serum Anti-Müllerian Hormone (AMH) levels have been shown to be lower among women who have experienced recurrent pregnancy loss (RPL) compared with the general population. However, it is unclear whether it can predict livebirth. This study aims to determine whether AMH can predict the likelihood of a livebirth in women with RPL. Prospective analysis of a consecutive cohort of women undergoing investigation for RPL in a tertiary referral centre over a seven year period (August 2014 -December 2021). Analysis was performed using descriptive statistics, chi-square models and logistic regression models adjusting for maternal age and previous livebirth. Exclusion criteria for the regression analysis included abnormal parental karyotype and abnormal pelvic ultrasound scan. Pregnancy outcome was defined as livebirth or further pregnancy loss. There were 488 women who underwent investigation of RPL during the study period. Of these, 65.2% (n = 318) conceived following attendance at the clinic. The majority of these women (69.4%, n = 221) proceeded to have a livebirth. There were no differences in median AMH levels between the livebirth group and the further pregnancy loss group (11 pmol/L vs 9 pmol/L respectively (p = 0.083). AMH did not affect clinical pregnancy rates (p = 0.77, 95% CI = 0.99 [0.98, 1.01]) or pregnancy outcome (p = 0.30, 95% CI = 1.01 [0.99, 1.04]). Abnormal pelvic ultrasonography (p = 0.04) and an abnormal parental karyotype (p = 0.04) were associated with an increased likelihood of a subsequent pregnancy loss. Although AMH levels may have some utility in counselling of some couples with RPL, these contemporaneous data indicate that low AMH does not negatively influence subsequent pregnancy outcome in women with recurrent pregnancy loss.
