Reproductive Health Peptides

Reproductive peptides play central roles in the hypothalamic-pituitary-gonadal (HPG) axis, controlling fertility, ovulation, spermatogenesis, and pregnancy-related physiology. Several peptides in this category have become indispensable tools in assisted reproductive technology (ART), while others represent emerging research directions in reproductive medicine.

The GnRH antagonists cetrorelix and ganirelix are FDA-approved cornerstones of modern IVF protocols, preventing premature LH surges during controlled ovarian stimulation. Gonadorelin, the synthetic form of gonadotropin-releasing hormone, is used diagnostically and therapeutically for hypothalamic amenorrhea. Kisspeptin-54 and its shorter fragment kisspeptin-10 are being investigated as novel IVF triggers that eliminate the risk of ovarian hyperstimulation syndrome (OHSS), with MVT-602 representing the first synthetic kisspeptin receptor agonist to enter clinical development. Oxytocin, one of the most well-known peptide hormones, has established roles in labor induction and lactation, alongside emerging research in social behavior and psychiatric conditions.

The clinical evidence in this category is generally strong, as several of these peptides have been evaluated in rigorous randomized controlled trials and have received regulatory approval for specific reproductive indications.
