Research Overview

Kisspeptin-52

Human and animal studies show kisspeptin-52 can acutely increase gonadotropin secretion and activate the hypothalamic-pituitary-gonadal axis. It has been explored in fertility research and assisted-reproduction settings as a way to trigger endogenous reproductive hormone release.

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.
