The decapeptide gonadotropin-releasing hormone, also referred to as luteinizing hormone-releasing hormone with the sequence (pGlu-His-Trp-Ser-Tyr-Gly-Leu-Arg-Pro-Gly-NH₂) plays an important role in regulating the reproductive system. It stimulates differential release of the gonadotropins FSH and LH from pituitary tissue. To date, treatment of hormone-dependent diseases targeting the GnRH receptor, including peptide GnRH agonist and antagonists are now available on the market. The inherited issues associate with peptide agonists and antagonists have however, led to significant interest in developing orally active, small molecule, non-peptide antagonists. In this review, we will summarize all developed small molecule GnRH antagonists along with the most recent clinical data and therapeutic applications.

The downregulation of anti-adhesive regulatory proteins and upregulation of adhesive genes are critical for the receptive endometrium. This study was designed to determine whether switching between the anti-adhesive podocalyxin (PDX) and adhesive HOXA10 receptivity modulator occurs in the endometrium of women with recurrent implantation failure (RIF). Twenty-four patients with RIF who could not conceive for three or more cycles despite good-quality embryo transfer constituted the study group.

Objective: To compare in vitro fertilization treatment outcomes for the oral gonadotropin-releasing hormone (GnRH) antagonist elagolix (E) to the conventionally used injectable GnRH antagonist ganirelix (G) for achieving pituitary gonadotropin suppression during a controlled ovarian stimulation (COS) cycle.
Design: Retrospective cohort study.
Setting: Private university-affiliated fertility center.
