Research Overview

Buserelin

Buserelin has been studied extensively as a GnRH agonist in IVF down-regulation and other reproductive-endocrine protocols. Its use helped establish modern cycle-control approaches in assisted reproduction.

Lutropin alfa

Lutropin alfa has been evaluated in fertility protocols to restore LH signaling and endogenous testosterone production. It is a direct research/clinical analogue for men with low gonadotropin drive.
