Research Overview
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.
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.
