Kisspeptin
Libido
Studies published in JAMA Network Open found that giving kisspeptin can boost sexual responses in women and men who have hypoactive sexual desire disorder (HSDD) – a condition characterized by low sexual desire that is distressing to the individual.
Hormonal Balance in Men
Kisspeptin is also involved in the regulation of reproductive hormones in men. It stimulates the release of gonadotropins, which are essential for the production of sperm and testosterone.
Stimulation of Reproductive Hormones
Kisspeptin is a potent stimulator of gonadotropin-releasing hormone (GnRH), which, in turn, stimulates the release of gonadotropins—luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These hormones are essential for the regulation of the menstrual cycle and fertility in both men and women.
According to the NIH
Kisspeptin attenuates negative mood. This suggests that kisspeptin, in addition to its established role in the reproductive hormonal cascade, can also influence related sexual and emotional brain processing, thereby providing integration among reproduction, sexual responses, and bonding.
Oxytocin
Social Bonding
Oxytocin is perhaps best known for its involvement in social bonding. It enhances trust, empathy, and social interactions, fostering connections between individuals. Studies have shown that increased levels of oxytocin are associated with greater feelings of attachment and intimacy.
Reproductive Function in Women
Oxytocin plays a crucial role in childbirth and lactation. During labor, it stimulates uterine contractions, facilitating delivery. Additionally, it promotes milk ejection during breastfeeding, aiding in maternal-infant bonding.
Stress Regulation
Oxytocin acts as a natural stress reliever by reducing cortisol levels, the primary stress hormone. It counteracts the physiological effects of stress, promoting relaxation and emotional well-being.
Sexual Function
Oxytocin influences sexual behavior and arousal, contributing to sexual satisfaction and orgasm. Its release during intimate moments fosters feelings of closeness and emotional intimacy between partners.
Health and Healing
Emerging research suggests that oxytocin may have therapeutic potential in various medical conditions, including anxiety disorders, autism spectrum disorders, and even wound healing. Its role in promoting social support and reducing stress could have profound implications for mental and physical health
