Kisspeptin
A regulatory peptide central to reproductive endocrine signaling. Kisspeptin is one of the most-studied molecules in women’s hormonal research and the master regulator of the reproductive axis.
The peptide that starts the conversation.
Discovered in 1996, Kisspeptin is the peptide that effectively starts puberty. It sits at the very top of the reproductive hormone cascade, signaling the hypothalamus to release GnRH, which in turn drives the release of every downstream sex hormone.
For women, Kisspeptin has emerged as one of the most important molecules in modern reproductive endocrinology. The hormonal shifts that define a woman’s reproductive years — cycle regularity, fertility, menopause — trace back to kisspeptin signaling more directly than almost any other compound.
Published research has documented Kisspeptin’s role in regulating the menstrual cycle, supporting fertility research, and exploring the hormonal landscape of perimenopause. It is also under active investigation for its connections to mood, libido, and the broader experience of hormonal change.
