Researchers from Turku PET Center and Åbo Akademi have conducted a groundbreaking study that uncovers the release of opioids in the brain during orgasms.
Opioids are known to regulate pain and pleasure, but their role in sexuality has been poorly understood. Using positron emission tomography (PET) and magnetic resonance imaging (MRI), Finnish scientists demonstrated how opioids are released in the male brain during orgasm. Sexual pleasure was also found to activate various brain regions.
