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.
Buserelin
Buserelin has been studied extensively as a GnRH agonist in IVF down-regulation and other reproductive-endocrine protocols. Its use helped establish modern cycle-control approaches in assisted reproduction.
