Abstract
Objective:
To describe the prevalence of CUA and evaluate reproductive and obstetric outcomes in a population of infertile women with these anomalies.
Method:
We conducted a retrospective cohort study between January 2014 and December 2023, including patients with CUA (n=50) and a control group (n=40) who underwent assisted reproductive technology (ART). We recorded and compared baseline characteristics, reproductive outcomes, and obstetric complications.
Results:
The prevalence of CUA was 1.6%. No significant differences were observed between groups in the number of oocytes, mature oocytes, fertilization rates, embryo development, or pregnancy and live birth rates. In the first IVF-ET cycle, pregnancy (28.5% vs. 14.3%, p=0.102) and live birth (25.7% vs. 9.5%, p=0.081) rates were similar between women with CUA and those with a normal uterus. Likewise, cumulative pregnancy (42% vs. 35%, p=0.552) and live birth (36% vs. 22.5%, p=0.247) rates did not differ. Obstetric outcomes, including first-trimester miscarriage, preterm delivery, fetal growth restriction, low birth weight, and cesarean delivery, were also comparable. Descriptive analysis by CUA subclass showed the lowest pregnancy rate in women with hemi-uterus (25%). Live birth rates were higher after septoplasty in women with complete septate uterus, but not in those with partial septate uterus.
Conclusion:
Pregnancy and live birth rates after ART were not significantly different between women with CUA and those with a normal uterus.
