This study aimed to evaluate the relationship between semen regurgitation and intrauterine insemination (IUI) outcomes. The results showed that regurgitation during the IUI procedure is not related to pregnancy outcome.
Objective: To evaluate the relationship between semen regurgitation and intrauterine insemination (IUI) outcomes. We hypothesized that clinical pregnancy rates and live birth rates would be reduced when regurgitation occurred. Design: Retrospective cohort study. Setting: A university-based reproductive endocrinology and infertility clinic. Patient(s): Retrospective review of 1,957 IUI cycles performed on 660 patients between July 2007 and May 2012. Intervention(s): None. Main Outcome Measure(s): The primary outcome was live birth. Secondary outcomes were positive serum pregnancy result and clinical pregnancy. Risk ratios (RRs) and 95% confidence intervals (CIs) were calculated using a cluster-weighted generalized estimating equations method to estimate modified Poisson regression models with robust standard errors to account for multiple IUI cycles in the same patient. Result(s): Live birth rates were similar in IUI cycles with and without regurgitation (6.3% vs. 6.8%, respectively, RR = 0.82, 95% CI [0.53-1.26]). Clinical pregnancy rates in the presence or absence of regurgitation were 10.5% vs. 10.0%(RR = 0.99, 95% CI [0.73-1.35]). Positive serumpregnancy tests after IUI did not differ by regurgitation status (15.0% vs. 15.4%, RR = 0.97, 95% CI [0.75-1.24]). Results were unchanged when adjusted for covariates (age, race and ethnicity, body mass index, duration of infertility, medication, infertility diagnosis, total motile count, and method of sperm preparation). Conclusion(s): The presence of regurgitation during the IUI procedure is not related to pregnancy outcome. (C) 2021 by American Society for Reproductive Medicine.)
