Product Introduction

Cetrorelix (CAS: 120287-85-6) is a synthetic decapeptide that functions as a potent gonadotropin-releasing hormone (GnRH) antagonist. By competitively binding to GnRH receptors in the pituitary gland, it effectively inhibits the secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). This mechanism helps prevent premature ovulation during controlled ovarian stimulation, making Cetrorelix an essential compound in assisted reproductive technologies (ART) and in vitro fertilization (IVF) protocols.
