There is inadequate evidence to recommend or refute the use of urinary hCG, as an ovulation trigger, in anovulatory women being treated with clomiphene citrate. We did not find trials evaluating the use of ovulation triggers in anovulatory women, being treated with other ovulation inducing agents.
hCG administration offers no outcome benefit over spontaneous ovulation in anovulatory women treated with clomiphene citrate.
This randomized controlled trial compared spontaneous ovulation versus hCG-triggered ovulation in anovulatory women treated with clomiphene citrate. No statistically significant differences were observed between the two groups in terms of ovulation and pregnancy rates.
