Analysis of pregnancy outcomes and associated risk factors for tuberculosis recurrence during pregnancy in patients with prior tuberculosis undergoing IVF-ET

Elevated estradiol levels (≥ 5000 pg/ml) on the day of human chorionic gonadotropin (hCG) trigger, as well as twin pregnancies, have been identified as independent risk factors for recurrent TB among pregnant patients with a history of TB who undergo embryo transfer. Given these findings, it is advisable for such patients to consider single embryo transfer and to utilize frozen embryo transfer cycles to mitigate the associated risks.
