A nutty Irishman landed in the hospital after he took matters into his own hands to treat his back pain – by injecting himself with his own semen, according to a report.

After injecting himself monthly for a year and a half, the unidentified 33-year-old developed a subcutaneous abscess in his arm, as well as emphysema and edema – excess fluid – under his skin, the Irish Times reported.

The man said he had been injecting his own semen, without medical advice, as an “innovative” method to treat his lower back pain.

He revealed that he injected one monthly “dose” of semen for 18 consecutive months using a hypodermic needle he bought online.

The patient was treated with an intravenous antimicrobial drip, but he decided to discharge himself without allowing doctors to drain the “local collection,” the news outlet reported.

The case was revealed in a report published by the Irish Medical Journal titled, “Semenly Harmless Back Pain: An Unusual Presentation of a Subcutaneous Abscess.”

Dr. Lisa Dunne of Adelaide and Meath Hospital in Tallaght, who authored the case report, found that there were no other reported cases of intravenous semen injection to be found anywhere in medical literature.
