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.
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.
