Attempting to compare the rates of premature luteinization (PL), clinical pregnancy, and cycle cancellation in ovulation induction-intrauterine insemination (OI-IUI) cycles with and without the GnRH antagonist, cetrorelix, a randomized-controlled trial was undertaken in which patients were randomized to one of two OI-IUI protocols. Those in the cetrorelix arm showed a significantly reduced rate of PL and no change in clinical pregnancy or cycle cancellation rate, leading to the conclusion that GnRH antagonists can decrease the rate of PL, but appear to have no effect on pregnancy or cycle cancellation in gonadotropin OI-IUI cycles.
