Impact of a positive Chlamydia trachomatis serology on cumulative IVF live birth rate.

Research Question: Does positive Chlamydia trachomatis serology have an impact on the cumulative live birth rate from IVF?

Design: A retrospective matched cohort study compared women with positive Chlamydia trachomatis serology (group A) who underwent IVF treatment between January 2016 and December 2021 with a control group of women with negative Chlamydia trachomatis serology (group B). The main outcome measures were the cumulative live birth rate per IVF cycle and the live birth rate per embryo transfer. Secondary outcomes were the cumulative rates of clinical pregnancy, ectopic pregnancy and pregnancy loss calculated per IVF cycle and per embryo transfer.
