What are GnRH agonists?

GnRH agonists are drugs with a longer half-life than the antagonists and great affinity for the GnRH receptor in the pituitary gland. These drugs are used in fertility treatments to prevent the release of FSH and LH hormones.

An example of a GnRH agonist drug is Synarel. Its objective is to suppress spontaneous ovulation during ovarian stimulation for in vitro fertilization (IVF).
