Yes. Although rare, penis fracture can occur when there is trauma to an erect penis.
During an erection, the penis is engorged with blood. If an engorged penis is bent suddenly or forcefully, the trauma can rupture the lining of one of the two cylinders in the penis (corpus cavernosum) responsible for erections — resulting in a penis fracture. The trauma most often occurs after accidental injury during intercourse, but can also occur due to aggressive masturbation or taqaandan, a cultural practice in which the top of an erect penis is forcefully bent.
A penis fracture is a painful injury. Signs might include a cracking sound, immediate loss of the erection, or the development of dark bruising of the penis due to blood escaping the cylinder. Sometimes the tube that drains urine from the body (urethra) is damaged as well, and blood might be visible at the urinary opening of the penis.
A penis fracture requires urgent medical attention. The injury can usually be diagnosed with a physical exam, and prompt surgical repair is typically recommended.
Left untreated, a penis fracture might result in deformity of the penis or the permanent inability to get or keep an erection firm enough for sex (erectile dysfunction).
