Background: Kisspeptin is a critical activator of hypothalamic gonadotrophin releasing hormone (GnRH) neurons and has significant potential to treat common reproductive disorders. To date, kisspeptin has solely been administered to humans via the intravenous or subcutaneous routes, however intranasal administration could offer a novel non-invasive delivery route. We therefore sought to determine the effects of intranasal kisspeptin on reproductive hormone release in humans for...

Background: There is emerging evidence that kisspeptin, a hormone with well-established reproductive effects, may also have important metabolic effects. Acute kisspeptin administration enhances insulin secretion under hyperglycaemic conditions in male rodents and men, and kisspeptin receptor agonism improves steatohepatits in male mice in a rodent model of non-alcoholic fatty liver disease. However, the metabolic effects of kisspeptin may exhibit sexual dimorphism as female (b...

Background: Kisspeptin is a critical activator of hypothalamic GnRH neurons and is essential for reproductive health. Emerging data reveals that kisspeptin-based therapeutics have substantial potential to treat reproductive, psychosexual and bone disorders. However, current delivery is limited to the subcutaneous or intravenous routes, presenting barriers to development. Alternative routes of administration would overcome this and capitalise on the benefits of kisspeptin-based...

Background: Kisspeptin is a potent regulator of GnRH neurons with potential to treat reproductive and psychosexual disorders. However, administration is limited to the subcutaneous or intravenous routes. These invasive routes limit clinical development. Herein, we comprehensively examine the translational potential of intranasal kisspeptin administration for the first-time using rodent, human and pharmaceutical studies.Methods:</...
