Gonadorelin (GnRH): Comprehensive Research Overview

Document Version: 1.0 Last Updated: December 2024 Classification: Research Paper - Hormone Therapeutics

Goal Relevance:

  • Support for fertility and conception by aiding ovulation in women with hormonal imbalances.
  • Assistance in diagnosing pituitary function issues to address hormone-related health concerns.
  • Help with hormone optimization for individuals experiencing low testosterone or other hormonal deficiencies.
  • Aid in fertility preservation for those undergoing treatments that may affect reproductive health.
  • Support for individuals with hypogonadotropic hypogonadism seeking to improve hormone levels and reproductive function.

1. Executive Summary

Gonadorelin is a synthetic decapeptide (pGlu-His-Trp-Ser-Tyr-Gly-Leu-Arg-Pro-Gly-NH₂) identical to naturally occurring gonadotropin-releasing hormone (GnRH). With a molecular mass of 1,182.2 Daltons, gonadorelin plays a central role in regulating reproductive function by stimulating the anterior pituitary to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

Mechanism and Clinical Use

Gonadorelin primarily stimulates LH synthesis and release, with lesser effects on FSH. Clinically, it was used for:

  • Diagnostic testing of pituitary function
  • Treatment of hypogonadotropic hypogonadism
  • Induction of ovulation in hypothalamic amenorrhea
  • Fertility preservation

Current Status: FDA-approved injectable gonadorelin was discontinued; available products (Factrel, Lutrepulse) no longer marketed in the US.
