About Gonadorelin
Synthetic GnRH that binds pituitary GnRH receptors; pulsatile dosing stimulates LH/FSH release; used to maintain HPG axis during TRT
About hCG
Glycoprotein hormone binding LH receptor on Leydig cells; stimulates testosterone production; prevents testicular atrophy during TRT; maintains spermatogenesis via LH-receptor-driven intratesticular testosterone

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.
hCG
No established clinical contraindications
Standard reproductive endocrinology panels establish HPG axis baseline before hCG use. Testosterone and E2 confirm gonadal response; LH suppression during treatment is an expected finding.
