Overview

Gonadorelin is a synthetic form of the naturally occurring gonadotropin-releasing hormone (GnRH). It stimulates the pituitary gland to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which in turn regulate testosterone production in men and ovulation in women. It is FDA-approved for diagnostic testing and fertility treatment. The pulsatile nature of GnRH secretion is critical for proper reproductive function.
