Impact of genital Chlamydia trachomatis infection on reproductive outcomes among infertile women undergoing tubal flushing: a retrospective cohort at a fertility centre in Uganda.

Background: The impact of current on clinical pregnancy and live birth rates among women undergoing tubal flushing is largely unknown. This study aimed to investigate whether current female genital infection affects the chance of achieving a clinical pregnancy and a live birth, among infertile women undergoing tubal flushing, at a fertility centre in Uganda.

Methods: A retrospective Cohort study at a peri-urban fertility centre. A total of 253 eligible women with tubal factor infertility, who underwent tubal flushing, were enrolled and categorised according to their exposure to current genital infection. These women were followed up for a period of 12 months, with the primary outcome measure being clinical pregnancy and live birth. Secondary outcome measures included pregnancy loss and procedural related adverse events.

Results: Exposure to current genital  infection reduced chance of clinical pregnancy (adjusted relative risk 0.42; 95% confidence interval, 0.18-0.96) and a live birth (adjusted relative risk 0.37; 95% confidence interval, 0.14-0.95) after tubal flushing. Women with current infection had an increased risk of adverse events (adjusted relative risk, 1.20; 95% confidence interval, 1.08-1.34). However, current infection did not affect the risk of spontaneous abortion and ectopic pregnancy.

Conclusion: Current genital  infection in women with tubal factor infertility, undergoing tubal flushing, lowers their chance of pregnancy and live birth.
