Kisspeptin is a hormone that has been shown to increase testosterone levels in men. It also helps stimulate follicle-stimulating hormone and luteinizing hormone (LH) production. These two hormones are responsible for stimulating ovulation in women and producing sperm in men.
It is believed that kisspeptin acts to regulate these sex hormones by stimulating the gonadotropin-releasing hormone (GnRH) neurons in the hypothalamus, which then triggers LH and FSH production and release from the pituitary gland. This results in the ovaries or testes producing the sex hormones estrogen and progesterone in females, or testosterone in males.
In some studies, kisspeptin has been shown to increase sex drive in both men and women. In one study, researchers found that men who were given kisspeptin responded more positively to erotic stimuli and had greater penile rigidity. Additionally, they had more activity in the parts of their brain related to sexual desire.
Another study found that kisspeptin can help to stimulate ovulation in women. In addition, it was found that the hormone can increase fertility in men. In the study, men who received kisspeptin had a higher sperm count than those who did not receive the treatment.
The peptide kisspeptin is often used by physicians to treat low testosterone. It is believed that it can be used as a safe alternative to hCG in men receiving hormone replacement therapy. It is also believed that the peptide can be used to prevent testicular atrophy. It is also used to help with erectile dysfunction in some patients. However, the use of kisspeptin for this purpose is still experimental.
