What is the Origin of Luteinizing Hormone Titration?

This practice is rooted in reproductive endocrinology, where pulsatile GnRH administration was established as the physiological stimulus for LH release. 'Titration' implies careful, incremental adjustment based on measured downstream hormone responses, usually testosterone or estradiol levels.

What is the Mechanism of Luteinizing Hormone Titration?

The mechanism involves matching the administered exogenous LH dose and frequency to the natural physiological secretory pattern required to maintain adequate Leydig cell function without causing receptor desensitization. Adequate LH signaling ensures the appropriate synthesis of testosterone from cholesterol precursors within the testes. Successful titration stabilizes circulating androgen levels within the optimal therapeutic window.

Luteinizing Hormone Titration

Meaning

Luteinizing Hormone (LH) Titration is the process of systematically adjusting exogenous LH administration, typically via pulsatile delivery or sustained analog therapy, to achieve optimal stimulation of gonadal steroidogenesis. This procedure is clinically relevant when addressing hypogonadotropic hypogonadism or optimizing endogenous function when the HPG axis is suppressed. Precise titration is necessary to avoid receptor downregulation.
