AMH and Infertility: In multilevel mixed-effects logistic regression model analysis for blastocyst collapse to predict the ploidy status (euploid or aneuploid) of embryos, morphokinetic parameters (t8, tSB, tB, ECC3, s3), time of biopsy (Day 5 or Day 6), ICM grade (A or B), TE grade (A, B or C), infertility duration, and level of AMH are taken into consideration as confounding (Table 1).
