General Description

Factrel, also known as gonadorelin hydrochloride, is a synthetic decapeptide gonadotropin-releasing hormone (GnRH) identical in structure to the naturally occurring hypothalamic peptide. It is formulated as the hydrochloride salt and consists of the sequence pGlu-His-Trp-Ser-Tyr-Gly-Leu-Arg-Pro-Gly-NH2.

Mechanism of Action

Factrel binds to GnRH receptors on anterior pituitary gonadotroph cells, stimulating the synthesis and secretion of both luteinizing hormone (LH) and follicle-stimulating hormone (FSH). This gonadotropin release stimulates gonadal steroidogenesis and gametogenesis within the hypothalamic-pituitary-gonadal axis.

Application

Indicated for the evaluation of hypothalamic-pituitary-gonadal function and in reproductive endocrinology diagnostics. Factrel is a synthetic GnRH identical to native hypothalamic hormone, used to assess pituitary reserve capacity and diagnose gonadotropin deficiency in infertility workups.

How does Factrel compare to synthetic GnRH superagonists?

Factrel is identical to native GnRH and stimulates an initial gonadotropin surge, whereas synthetic superagonist analogs are modified for enhanced potency and sustained receptor downregulation.
