What is the Origin of Exogenous Gonadotropins?

The origin lies in the development of reproductive endocrinology and assisted reproductive technologies, where purified or recombinant hormones became available for clinical application. The term differentiates these administered substances from those naturally produced by the body.

What is the Mechanism of Exogenous Gonadotropins?

These exogenous preparations bind directly to gonadotropin receptors on ovarian granulosa cells or testicular Leydig cells, activating intracellular signaling pathways that promote steroidogenesis and gamete maturation. By bypassing the native pituitary regulation, they allow for controlled, supra-physiological stimulation of the target endocrine organs.

Exogenous Gonadotropins

Meaning

Exogenous Gonadotropins are therapeutic agents administered externally that mimic the action of endogenous pituitary hormones, Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH), to stimulate gonadal function. These compounds are clinically utilized to induce follicular development in females or to support spermatogenesis in males when the native hypothalamic-pituitary axis is insufficient. Their administration requires careful endocrine monitoring.
