It turns out that injecting yourself with your own semen is not a good cure for anything.

So here's a thing you should never, ever do. In a case report published in the Irish Medical Journal, researchers described a man who was injecting himself with his own semen in a bid to cure his back pain. The 33-year-old man took himself to the hospital with severe back pain after lifting something heavy. He'd apparently been experiencing chronic lower back pain for some time. When doctors examined him, they discovered a red, swollen spot on his right arm. It turns out that's where he'd been injecting his own spunk.

The case report describes his semen therapy as "an innovative method to treat back pain" devised independently "of any medical advice," which is a very nice way to put that. Perhaps most alarmingly, he'd been giving himself injections for a whole 18 months. Prior to arriving in hospital, he'd just given himself three "doses" both into his veins and into his muscle, which caused the swelling. So not only was he injecting semen into his own body, he kept missing his veins. Just for the record, injecting random stuff into your veins can cause infections and clots, which can be dangerous, even potentially life-threatening. And injecting semen with a needle anywhere into your body is a bad idea. But in this case, he was injecting it into his soft tissue where it was just kind of hanging out and causing inflammation. An X-ray showed exactly where the problem lay. He had an abscess and cellulitis, a serious infection of the tissue under the skin.
