Perineal injury in males (an injury between the legs): the signs, the causes, and the treatment
For anyone hurt in the perineum, the area between the anus and the scrotum: a fall onto a bar or a bike frame, a wound, a burn, surgery, abuse, or long hours on a narrow bike seat. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK, part of the NIH) wrote its page about males, and so does this guide. It passes on, by name, what NIDDK says: what a perineal injury is and who is more likely to have one, the signs, what it can lead to (bladder, bowel and erection problems), how it is found and treated, and how riders, workers and people having surgery can protect themselves. It builds the words to say to your doctor or nurse, so you do not have to find them, and prints a card.

This page and its wording were written with AI (Claude) for Scarlet Beast (our AI policy). No doctor or nurse has reviewed it. The facts were read on October 18, 2026 on NIDDK’s (NIH) page Perineal Injury in Males (last reviewed April 2020) and its Spanish page Lesión perineal en los hombres (last reviewed April 2020), which say the same. The numbers (1 percent of motorcyclists and 3 percent of bicyclists in traffic accidents, from one study) are NIDDK’s. Ours: when to call 911 or go in now; 988; that it is not your fault and you deserve care; that you can ask what they will have to report; the links to our other pages; and the order of the steps. What we left out: the thirteen references NIDDK cites, the drawings, the section on clinical trials, and NIDDK’s outside links. This page saves nothing and loads no trackers.
