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.
Follitropin alfa
Clinical literature supports follitropin alfa for male infertility, especially when combined with LH activity to optimize testicular output. Its role is strongest in hypogonadotropic hypogonadism and assisted reproduction protocols.
