Can kisspeptin be a new treatment for sexual dysfunction?

The neuropeptide kisspeptin activates the hypothalamic-pituitary-gonadal (HPG) axis and influences neural circuits controlling sexual behavior. Animal studies have determined its sex-specific roles in reproductive behaviors, whereas human research has linked kisspeptin to increased brain activity in regions associated with sexual and emotional processing, making it a potential treatment for disorders of sexual desire. Here I discuss the current evidence on the promise of kisspeptin as a therapy for sexual dysfunction, highlight the challenges currently hindering its application, and advocate future studies focusing on sex-specific effects and interactions within the neuroendocrine system. Understanding its broader physiological roles and improving delivery methods will be key to unlocking kisspeptin's therapeutic potential.
