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.
Nafarelin
Nafarelin has a long history in reproductive medicine, especially for endometriosis and cycle suppression. Studies show it down-regulates the HPG axis after an initial stimulatory flare.
