"This is a rare occurrence," said a Loyola University (Chicago) neurology professor in September, describing to WebMD.com only the seventh reported case of someone's suffering a stroke during orgasm. Several things must be present in series to create the condition, including having an unnatural opening between the two upper chambers of the heart (a "PFO"). Also, a blood clot must develop and break loose and then get sucked through the PFO at the moment of ecstasy, sending it directly to the brain.
