Triptorelin, sold under the brand name Decapeptyl among others, is a medication that acts as an agonist analog of gonadotropin-releasing hormone, repressing expression of luteinizing hormone (LH) and follicle-stimulating hormone (FSH).[3][4]

It is a decapeptide (pGlu-His-Trp-Ser-Tyr-D-Trp-Leu-Arg-Pro-Gly-NH2) and a gonadotropin-releasing hormone agonist (GnRH agonist) used as the acetate or pamoate salts.

Primary indications include endometriosis,[5] for the reduction of uterine fibroids, to treat prostate cancer, and to treat male hypersexuality with severe sexual deviation.[4] The drug has also been used off label to delay puberty in patients with gender dysphoria.[6]

It was patented in 1975 and approved for medical use in 1986.[7] It is on the World Health Organization's List of Essential Medicines.[8]
