Background: Successful reproduction relies on integration of sensory cues of attraction with corresponding emotions and behaviours. However, the intrinsic factors integrating these fundamental aspects of human attraction with limbic and reproductive pathways have not been fully identified. Kisspeptin is a crucial activator of the reproductive axis and together with its receptor is widely expressed throughout the limbic and olfactory systems in humans suggesting a potential rol...

BackgroundStructured lifestyle modification programmes are offered as first line treatment to patients referred to bariatric specialist services. We sought to describe changes in anthropometric and metabolic characteristics in a cohort of bariatric patients following completion of an eight-week, multidisciplinary group-based lifestyle intervention focussed on diet and physical activity.MethodsWe conducted a p...

Hypoactive sexual desire disorder (HSDD) is the most prevalent female sexual health complaint worldwide, affecting 1-in-10 women. It is characterised by a persistent lack of desire for sexual activity and sexual fantasies, causing distress or interpersonal difficulties. Treatment options are limited, however, melanocortin-4 receptor (MC4R) agonists have emerged as a promising therapy for HSDD, through unclear mechanisms. Investigating the pathways involved is crucial for our u...

Introduction: Hypoactive sexual desire disorder (HSDD) is characterized by a persistent deficiency of sexual fantasies and desire for sexual activity, causing marked distress or interpersonal difficulty. It is the most prevalent female sexual health problem worldwide, affecting approximately 1 in 10 women, but has limited treatment options despite its substantial health, social, and economic burden. Melanocortin-4 receptor (MC4R) agonists have emerged as a promising therapy fo...

Background: Hypothalamic KNDy neurons have recently been identified as key regulators of reproductive function by releasing three neuropeptides namely kisspeptin, neurokinin B (NKB) and dynorphin. Animal studies show they interact to control pulsatile GnRH release, which is vital for fertility. In animals, kisspeptin stimulates, NKB modulates and the opioid dynorphin inhibits GnRH pulsatility. However, the interaction of these peptides has never been studied in humans. To inve...

Hypoactive sexual desire disorder (HSDD) is a persistent lack of sexual desire, causing marked interpersonal distress. It is the most common global female sexual health problem, although the precise pathophysiology remains uncertain. Existing treatment options are limited by their efficacy and side effects. The neuropeptide kisspeptin offers a potential therapeutic target given its emerging role in modulating reproductive behaviour. Using a combination of psychometric, neuroim...

Kisspeptin is a crucial activator of reproductive function, stimulating GnRH neurons in the hypothalamus. However, kisspeptin and its receptor are also expressed in other brain regions including the limbic system, which has key roles in emotional processing. Kisspeptin signalling in the limbic system modulates emotional and sexual brain processing during tasks, however the effects of kisspeptin on underlying resting brain activity have not yet been studied. This is vital for o...
