Abstract

Research questionWhat is the impact of high serum anti-Müllerian hormone (AMH) concentrations on fertilization and embryo development among infertile women undergoing treatment with assisted reproductive technology (ART)? DesignRetrospective study of 1036 infertile women undergoing ART; women were divided into three groups according to serum AMH concentrations: AMH <1.1 ng/ml, 1.1–5.0 ng/ml and >5.0 ng/ml. The fertilization and embryo development rates of patients with different AMH concentrations and after stratification according to age were compared. ResultsWomen with high AMH concentrations were younger and had higher testosterone concentrations (0.4 ± 0.13 versus 0.3 ± 0.12 versus 0.3 ± 0.08 µg/dl, P < 0.001) than women with low AMH concentrations. However, analysis of the embryo development rate showed negative outcomes for women with high AMH concentrations, including a poor fertilization rate (76.3 ± 17.36 versus 82.1 ± 19.15 versus 82.4 ± 25.38, P = 0.003), and poor day 3 embryo development rate (55.6 ± 23.88 versus 62.6 ± 26.52 versus 62.8 ± 32.65, P = 0.014). Multivariate linear regression analysis showed significantly negative correlations of the AMH concentrations with the fertilization rate (P < 0.001) and day 3 embryo development rate (P = 0.006). Subgroup analysis showed that age 30 years or younger had a significant negative correlation with AMH and the embryo development rate, including the fertilization rate (P < 0.001) and day 3 embryo development rate (P = 0.037). ConclusionThese results suggest that high serum AMH concentrations, contributing to a hyperandrogenic environment and leading to decreased oocyte developmental competence, may have a negative impact on fertilization and the early stage of embryo development in women undergoing treatment with ART.
