%X Early spontaneous abortion (ESA) is a common adverse pregnancy outcome mainly attributed to embryo chromosomal abnormalities. However, as a quantitative marker, whether the anti-Müllerian hormone (AMH) can reflect oocyte quality is still controversial. By integrating biological evidence and adjusting many cofounders, this study aimed to clarify the controversies about the association between AMH and ESA caused by embryo aneuploidy during assisted reproductive technology (ART) treatment. We strictly preselected 988 patients receiving first ART treatment for analyzing clinical data, while 55 of them acquired chorionic villi karyotype results. In addition, 373 biopsied embryos from 126 patients receiving preimplantation genetic diagnosis (PGT) were tracked to compare embryo karyotypes. Univariate and multiple factor regressions were applied to analyze the risk factors leading to ESA. As covariates unadjusted, AMH (odds ratio 0.87, 95% CI 0.82-0.93) was the significant variable contributing to ESA. However, AMH played no significant role in the following regression models after age was adjusted. Also, AMH had no significant association with ESA in most age-adjusted subgroups, except in the male factors engaged subgroup. Additionally, compared to the patients with euploid chorionic villi karyotypes, those with aneuploid karyotypes were older and acquired fewer oocytes, yet their AMH levels were not significantly different. Furthermore, the embryo aneuploidy was independent of AMH while associated with maternal age, retrieved oocyte number, and embryo quality. This study suggested that AMH was unassociated with the ESA caused by embryo aneuploidy in ART therapy. As a critical cofounder, age remains the variable closely related to ESA.
