Assessing the adequacy of gonadotropin-releasing hormone agonist leuprolide to trigger oocyte maturation and management of inadequate response

A small minority of patients triggered with GnRH agonist had an inadequate response. Rescheduling of oocyte retrieval after hCG retrigger yielded similar IVF outcomes. Evaluation of trigger response based on serum LH and P concentrations is time dependent. Patient characteristics suggestive of hypothalamic hypofunction were predictive of an inadequate response to the GnRH agonist trigger.
