A man tried curing his back pain by injecting himself with his own semen, only to land in the hospital.

The case study, called "'Semenly' Harmless Back Pain: An Unusual Presentation of a Subcutaneous Abscess," and published in the Irish Medical Journal, notes the 33-year-old "devised this 'cure' independent of medical advice."

The doctors found "no other reported cases of intravenous semen injection found across the medical literature. A broader search of internet sites and forums found no documentation of semen injection for back pain treatment or otherwise." They did, however, note there was a report on the effects of human semen injection into rats and rabbits, from 1945.

"While suicide attempt by intravenous injection of harmful substances is well described, this unique case demonstrates risks involved with innovative treatments prior to clinical research in the form of phased trials inclusive of safety and efficacy assessments," the report continues.

"This is the first reported case of semen injection for use as a medical treatment."

The man is said to have "revealed he had injected one monthly 'dose' of semen for 18 consecutive months using a hypodermic needle which had been purchased online. Upon this occasion the patient had injected three 'doses' of semen intra-vascularly and intra-muscularly."

His failed attempts at self-injection caused semen to build up in the soft tissues of his arm. He was then "immediately commenced on intravenous antimicrobial treatment" and x-rayed, which "demonstrated subcutaneous emphysema."

The patient recovered and opted to discharge himself, without having an incision made to drain his forearm.

The moral of this wild story:

While it is the first ever described case of intravascular semen injection and associated abscess in the medical literature its lessons can be applied on a broader scale; the dangers of venepuncture when carried out by the untrained layperson are highlighted as well as the vascular and soft tissue hazards surrounding the attempted injection of substances not intended for intravenous use. The case also demonstrates the risks involved with medical experimentation prior to extensive clinical research in the form of phased trials inclusive of safety and efficacy assessments.

Or, put more simply: Don't shoot yourself up with random substances, your own bodily fluids most definitely included.
