  OBJECTIVE: To investigate if administration of an additional dose of gonadotropins concomitantly to human chorionic gonadotropin (hCG) trigger increases pregnancy rates in patients undergoing intrauterine insemination (IUI) with controlled ovarian hyperstimulation (COH).

STUDY DESIGN: This is a retrospective cohort study of all gonadotropin-IUI cycles performed by a single physician in a private practice between January 2012 and September 2013. Control cycles were those in which follicle-stimulating hormone (FSH) was discontinued prior to the day of hCG trigger shot, and study cycles received continuous FSH including the day of hCG trigger shot. A total of 423 cycles from 239 patients were included; 275 (65.5%) were control cycles (137 patients), and 146 (34.7%) were study cycles (102 patients).

RESULTS: Pregnancy rates were comparable in both control and study groups (15.27% vs. 15.07%, respectively, p=0.956). There was a 42% increase in multiple gestations in the study group; however, the difference was not statistically significant (p=0.155). Upon multivariate logistic regression, male factor infertility was the only variable that was associated with pregnancy outcomes.

CONCLUSION: Continuous administration of FSH including the day of hCG trigger in patients undergoing COH with IUI does not seem to increase pregnancy rates. Our suggested protocol might be beneficial in patients with poor ovarian response.
