No association between LH levels and ovarian response in oocyte donors triggered with gonadotropin-releasing hormone agonist: A prospective study.

Objective: Are circulating luteinizing hormone (LH) levels predictive of ovarian response in oocyte donors triggered with gonadotropin-releasing hormone (GnRH) agonists?

Study Design: A prospective cohort study with 224 oocyte donation cycles between 2021 and 2022 at a single center, examined the relationship between circulating luteinizing hormone (LH) levels and ovarian response. Oocyte donors underwent GnRH antagonist downregulation followed by GnRH agonist trigger. LH, estradiol, and progesterone levels were measured on day one of stimulation, trigger-day and 12 h post-trigger.
