Gamma-hydroxybutyrate (GHB), a drug used for narcolepsy and abused recreationally, has prosexual effects in healthy men. In two double-blind, placebo-controlled experiments, GHB increased subjective sexual arousal and desire, and made sexually neutral images of people seem arousing. Brain scans showed that GHB boosted activity in reward regions like the nucleus accumbens when viewing erotic pictures, and increased connectivity between the nucleus accumbens and the ventromedial prefrontal cortex. The findings indicate GHB enhances hedonic sexual functioning and lowers the threshold for perceiving erotic cues by sensitizing mesolimbic reward pathways.
