A 2016 neurological study looking at brain imaging suggests orgasms from different kinds of stimulation activate overlapping but partially distinct neural pathways. Orgasms actually lower dopamine (and raise testosterone)When you experience an orgasm, the body releases numerous hormones and neurotransmitters. “The study we conducted found good evidence that PGAD can be caused by Tarlov cysts [fluid-filled sacs that grow on nerves] that form on the genital sensory nerves,” Komisaruk explains. “The male pig’s saliva contains a metabolite of testosterone,” explains Komisaruk. In fact, Komisaruk compares an orgasm’s impact on the brain as similar to that of an epileptic fit.
