It tells the brain to release the hormones that control the ovaries and testes, which is how puberty starts.
What does the research show?
- In a 2014 study, a single injection of kisspeptin-54 triggered egg maturation in 53 women having IVF. Embryos were transferred for 92% of them, and 23% (12 of 53) had a clinical pregnancy.
Known risks and side effects
- Its long-term safety and best use are still being studied.
Is Kisspeptin approved?
Tested in people, but not approved as a medicine.
