AMH and Infertility: As presented in Table 3, univariate analysis revealed that age (OR = 0.91, p < 0.001), AMH level (OR = 1.06, p < 0.001), duration of infertility (OR = 0.96, p = 0.044), severe intrauterine adhesions (OR = 0.47, p = 0.001), balloon retention time (OR = 1.01, p = 0.002), endometrial thickness prior to embryo transfer (OR = 1.24, p < 0.001), frozen–thawed embryo transfer (OR = 0.38, p < 0.001), blastocyst transfer (OR = 1.92, p < 0.001), and transfer of high-quality embryos (OR = 1.30, p = 0.002) were all significantly associated with pregnancy outcomes.
