About Gonadorelin
Synthetic GnRH that binds pituitary GnRH receptors; pulsatile dosing stimulates LH/FSH release; used to maintain HPG axis during TRT
About LH
Binds LH receptors on testicular Leydig cells, stimulating the cholesterol → testosterone biosynthetic pathway. In women, the LH surge triggers ovulation and supports luteal phase progesterone production.

Gonadorelin
No established clinical contraindications
Standard reproductive endocrinology panels establish HPG axis baseline. LH and FSH confirm pituitary response to gonadorelin; testosterone, E2, and SHBG reflect downstream gonadal output.
