1. Invaginated.
That’s the technical term doctors use to describe your penis being turned inside-out . . . er, outside-in. And yes, it could happen to you.Also known as “trapped penis,” invagination is usually the result of some kind of forceful impact on your rod. Basically, your penis is smashed straight back into your body with so much force that it becomes “trapped” in the fatty, subcutaneous tissue located between your pelvis and pecker, explains Hsin-Kai Wang, M.D., of Taipei Veterans General Hospital in Taiwan.
According to photos from Dr. Wang’s recent case study of a motorcycle accident victim, this condition resembles an empty sheath of skin not unlike the end of an elephant’s trunk. (A friendly warning: DO NOT Google “invaginated penis.”)
The good news is that this sort of accident is very uncommon, Wang says. Also, it’s largely reversible through “manual extraction” and surgery. “There was no direct injury to the penis during the incident,” Dr. Wang said of his very lucky report subject. This guy was able to have sex and urinate normally after his penis was “extracted”—which is a lot more than we can say for most of the unfortunate SOBs on this list.

6. Trouble with the Curve
A plaque buildup in your penis causes Peyronie’s disease—a dramatic curve in your Johnson that makes erections painful and sex difficult. Even more frightening: Between 65,000 and 120,000 middle-aged men are diagnosed with the disease each year in the United States. Drugs or surgery may help. But a full recovery isn’t guaranteed, says Culley C. Carson III, M.D., of the University of North Carolina.7. Broken Penis

8. Doggone It

9. A Permanent Gesture
After having his girlfriend’s initials tattooed on his shaft, an Iranian man enjoyed a 3-month erection followed by a permanent state of semi-rigidness. The cause: abnormally high blood flow resulting from the tattoo artist’s needle going a little too deep. Since he could still have sex, the guy decided he’d just live with it. Think of it as a radical cure for whiskey-dick.
10. Rough Day at Work
