Vyleesi is thought to enhance the brain’s sensitivity to sexual stimuli via melanocortin agonism1,2

Vyleesi is a melanocortin receptor agonist that nonselectively activates several receptor subtypes, with sexual effects mediated by the melanocortin-4 receptor1,2

Vyleesi is thought to work in brain areas showing altered activity in women with HSDD.

The exact mechanism by which Vyleesi improves HSDD in women is unknown.1,2

Activation in the supplementary motor areas, which regulates responses to visual erotic stimuli.2


Activation in the cerebellum, which promotes sexual arousal regions in the normal response to erotic stimuli.2

Deactivation in the secondary somatosensory cortex (S2), which may reduce self-consciousness.2
