| Explanation |
Ganirelix acetate (or diacetate) is an injectable competitive gonadotropin-releasing hormone antagonist (GnRH antagonist). It works by blocking the action of GnRH upon the pituitary, thus rapidly suppressing the production and action of LH and FSH.

| BiologicalActivity |
Ganirelix is a gonadotropin releasing hormone (GnRH) antagonist. It blocks a natural hormone called GnRH that typically releases other hormones to prepare your body for ovulation (release of an egg from your ovary). By blocking GnRH, ganirelix temporarily delays ovulation. It's used to prevent eggs from being released too early and can help your provider be more successful during your egg retrieval procedure.

| Reference |
- Use of GnRH antagonists in patients with an a priori poor IVF prognosis results in predictably poor outcomes. Patients without factors predicting poor outcome have acceptable PRs. The pattern of E2 rise immediately after initiation of GnRH antagonists does not predict cycle outcome. Oral contraceptives can be successfully used to schedule antagonist-based IVF cycles but might increase the risk of cycle cancellation in some patient populations.

- Elevated estradiol (E(2)) levels predispose to development of ovarian hyperstimulation syndrome (OHSS). Since GnRH antagonist is associated with a reduction in E(2) levels, we hypothesized that GnRH-antagonist treatment of women down-regulated with GnRH agonist who are at risk of OHSS might reduce E(2) levels and avoid cycle cancellation.
- Gustofson, R. L., Segars, J. H., & Larsen, F. W. (2006). Ganirelix acetate causes a rapid reduction in estradiol levels without adversely affecting oocyte maturation in women pretreated with leuprolide acetate who are at risk of ovarian hyperstimulation syndrome. Human Reproduction, 21(11), 2830-2837.
- Ganirelix is effective, safe, and well tolerated. Compared with leuprolide acetate, ganirelix therapy has a shorter duration and fewer injections but produces a similar pregnancy rate.
