Ganirelix

Subcutaneous injection

Overview

A synthetic decapeptide GnRH antagonist that competitively and reversibly blocks GnRH receptors on pituitary gonadotroph cells. Ganirelix rapidly suppresses LH secretion within hours of administration, preventing premature ovulation during assisted reproductive technology (ART) cycles.

Mechanism of Action

Its mechanism provides immediate suppression without the flare phase associated with GnRH agonists..

Research Summary & Key Findings

FDA-approved for prevention of premature LH surges during controlled ovarian hyperstimulation. Clinical trials demonstrated equivalent pregnancy rates to GnRH agonist protocols with significantly reduced OHSS risk and shorter stimulation duration. The fixed-start protocol (day 5-6 of stimulation) offers simplicity and predictability in IVF cycle management.

Clinical Status

FDA Approved
