The availability of gonadotrophin-releasing hormone (GnRH) antagonist for ovarian stimulation protocols has generated many meta-analyses comparing it to GnRH agonist long protocols. These meta-analyses have yielded conflicting results for pregnancy rate, with a tendency towards a better outcome for GnRH agonists.
The ovarian cycle is regulated by the interaction of hormones produced by the hypothalamic-pituitary-gonad. There are five main hormones involved in this process: GnRH, FSH, LH, estradiol and progesterone. The cycle is divided into three phases: follicular, ovulation, luteal phase.
