AMH and Infertility: Table 1 presents the characteristics of patients in the D5 and D6 blastocyst groups that underwent freeze-thaw transfer. The data indicated that both groups exhibited similar characteristics. Specifically, there were no statistically significant differences between the groups regarding age, BMI, endometrial thickness, infertility type, infertility duration, number of miscarriages, basal hormone levels, or anti-Müllerian hormone (AMH) levels. Table 2 displays the PGT results for both the D5 and D6 blastocyst groups in the context of FET.
