Abstract

Abstract Background Previous studies have investigated the effects of anti-Müllerian hormone (AMH) and AMH type II receptor (AMHR2) polymorphisms on ovarian stimulation outcomes, but the results were inconsistent. Methods We searched PubMed, Web of Science, Embase, and Cochrane Central Register of Controlled Trials databases for the literature used in this meta-analysis. The meta-analysis was performed with a random effects model with RevMan 5.3.5. Results were expressed as the relative risk (RR) for discrete data and the mean difference (MD) for continuous outcomes with a 95% confidence interval (CI). Results Seven studies with 2078 participants were included. More metaphase II (MII) oocytes were retrieved in the T allele carrier of AMH (rs10407022) in the dominant model (MD: 1.20, 95% CI: 0.76 to 1.65, I2 = 0%, P < 0.00001), homozygote model (MD: 1.68, 95% CI: 0.35 to 3.01, I2 = 70%, P = 0.01) and heterogeneity model (MD: 1.20, 95% CI: 0.74 to 1.66, I2 = 0%, P < 0.00001). Oocytes retrieved from the Asian region in the TT carrier were significantly lesser than those in the GG/GT carrier in AMH (rs10407022) (MD: -1.41, 95% CI: − 1.75 to − 1.07, I2 = 0%). Differences in the stimulation duration, gonadotropin (Gn) dosage, and pregnancy rate were insignificant. Conclusions Our analysis indicated that the polymorphisms of AMH/AMHR2 could influence the ovarian stimulation outcomes. Prospective studies with a larger sample size and more rigorous design are needed in the future to further confirm these findings.
