Lower cumulative live birth rates in cured endometrial tuberculosis patients after one ART cycle including all subsequent frozen-thaw cycles: A matched-pair study.

Objective: To investigate the outcomes of the first ART cycle including all subsequent frozen-thaw cycles from the same oocyte retrieval till first live birth in women with cured endometrial tuberculosis.

Study Design: This is a 1:4 matched-pair study, 113 cured endometrial tuberculosis patients (TB group) and 452 patients of non-tuberculosis (Non-TB group) matched for age, basal E2, basal FSH and ovulation protocol who underwent first complete ART cycles in our institution during December 2010 and December 2015 were included in the study. The baseline characteristic, clinic data, and IVF treatment outcomes were compared and analyzed between the two groups.

Results: Compared with the Non-TB group, the cumulative clinical pregnancy rates was similar (64.6% vs 65.1%, p = 0.89) but the cumulative live birth rates (40.7% vs 52.7%, p < 0.00) were significantly lower and the spontaneous abortion rates (37.0% vs 13.2%, P＜0.05 was significantly higher in TB group. There was no significant difference in the clinical pregnancy rates, live birth rates and spontaneous abortion rates between the fresh cycles and frozen-thaw cycles in the TB group.

Conclusion: Women may have increased risk of miscarriage and decreased CLBRs after cured endometrial TB infection when undergoing IVF.
