A 51-year-old man's pleasure soon turned to pain when he experienced a brain aneurysm after masturbating, according to a case study in the Journal of Stroke and Cerebrovascular Diseases.

According to doctors in Japan, who penned the study and treated the unnamed man, he masturbated multiple times every day before he experienced a subarachnoid hemorrhage, a brain aneurysm that causes blood to seep into your skull, according to the Cleveland Clinic.

Though the man survived and was discharged from the hospital two weeks after admission, a doctor, who didn't treat the patient, says he was lucky. According to neuropsychologist Dr. Amee Baird, 40% of brain aneurysm patients die, the New York Post reported.

Baird also told the New York Post that 14% of ruptured aneurysm patients had a blood vessel near their brain explode after sex or self-pleasure. According to the case report's authors, there are only two other known cases of masturbation-related stroke.

After masturbating, the man came down with severe headaches and vomiting

The man knew something was wrong when he had a sudden "thunderclap" headache and couldn't stop vomiting, according to the case report.

When he arrived at Nagoya City University Hospital in Japan, tests revealed he had low blood pressure and brain fog. Doctors knew these were signs of a brain and heart related illness, so the man underwent a CT scan on his brain.

They found he experienced a potentially fatal subarachnoid hemorrhage. Since an orgasm can lead to increased heart rate and blood pressure, they believe the man's climax led to his aneurysm.

To treat the man, doctors stuffed the aneurysm sac in his brain with surgical coil material to prevent further bleeding.

Then, they kept him on bed rest at the hospital for two weeks. By the end of his stay, the man was fully recovered, according to the doctors on the case.
