A GnRH decapeptide that suppresses sex hormones through continuous receptor stimulation.
Also known as: Leuprorelin · Lupron
Part of the Foundational & therapeutic peptides cluster
Overview
Leuprolide (leuprorelin) is a synthetic decapeptide analog of gonadotropin-releasing hormone. Given continuously it desensitizes pituitary GnRH receptors, lowering testosterone and estradiol, and is an approved therapeutic for hormone-responsive cancers and gynecologic conditions.

Source & context
Biological / chemical source: Synthetic decapeptide analog of GnRH
Primary research or clinical context: Approved for prostate cancer, endometriosis, uterine fibroids and central precocious puberty
Agonist paradox
Although leuprolide activates the GnRH receptor, sustained non-pulsatile exposure down-regulates the receptor after an initial flare, ultimately shutting off luteinizing hormone and follicle-stimulating hormone release. This illustrates how continuous versus pulsatile signaling produces opposite endocrine outcomes.
Clinical footprint
Depot formulations allow monthly to semiannual dosing for prostate cancer, endometriosis, uterine fibroids and central precocious puberty. Leuprolide is one of the most widely used peptide drugs and a reference example of GnRH-analog medicinal chemistry.
