Assessing the influence of gestational trophoblastic disease history on IVF-ET pregnancy outcomes: a retrospective...

To evaluate the impact of a history of gestational trophoblastic disease on pregnancy outcomes in in vitro fertilization-embryo transfer procedures(IVF-ET) and to utilize logistic regression to analyze potential risk factors influencing re-pregnancy outcomes among women with GTD histories undergoing IVF-ET.

This retrospective cohort study collected data from patients with a history of GTD who underwent IVF-ET at the hospital from January 2018 to January 2023. The study group comprised 27 women with a history of GTD. A control group of 54 women, matched at a 1:2 ratio, without a GTD history, was selected from those who underwent IVF-ET during the same period at the same hospital. Statistical analyses were employed to compare baseline characteristics, embryological parameters, and pregnancy outcomes between the two groups.

The study group exhibited significantly lower endometrial thickness (EMT) during the mid-luteal phase of the natural menstrual cycle, reduced EMT on the day of embryo transfer (ET), and a decreased blastocyst formation rate compared to the control group (p < 0.05). Furthermore, the study group had a higher number of uterine curettages prior to transfer, an increased rate of discarded embryos, and higher total sperm motility (PR + NP) in their spouses (p < 0.05). Logistic regression analysis revealed that a history of GTD does not significantly affect pregnancy outcomes post-IVF-ET.

A history of GTD does not significantly influence pregnancy outcomes following IVF-ET. Therefore, patients with a GTD history and their physicians can approach the IVF-ET process with less anxiety and adopt a more positive and rational outlook.
