Research Overview
hCG
Human studies show hCG can raise intratesticular and serum testosterone by mimicking luteinizing hormone at the testis. It is commonly studied in male hypogonadism and fertility-preservation settings.
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.
