01 / What is it?
What is it?
Kisspeptin is a family of natural peptides that helps control reproductive hormones. In the brain, it stimulates a signal called GnRH. GnRH then tells the pituitary gland to release LH and FSH, two hormones involved in fertility and sex-hormone production.

Kisspeptin
Why do people find it interesting?
Kisspeptin mainly affects hormone signalling in the brain. It helps trigger the release of hormones that play an important role in reproductive function, including fertility and sexual hormone regulation.
What might you notice?
Kisspeptin affects hormone signalling involved in reproduction. It can increase hormones such as LH and FSH, which are involved in testosterone production in men and ovulation in women. Research also suggests that kisspeptin may affect areas of the brain linked to sexual attraction and arousal, which may increase sexual desire or feelings of intimacy.
What happens in your body?
In simple terms, kisspeptin starts a chain of signals between the brain and reproductive organs: kisspeptin → GnRH → LH and FSH → ovaries or testes → sex-hormone production.
