Research Overview
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.
Leuprolide
Leuprolide is one of the best-studied GnRH analogs in reproductive medicine and assisted reproduction. It produces an initial flare followed by receptor desensitization and reduced LH/FSH output.
