Penises vary in shape and size, and while a slight bend isn't necessarily a cause for concern, a serious curve could be a serious problem. Peyronie's disease, also known as penile fibrosis, is a condition in which scar tissue builds up inside the penis and creates curvature in erections. Peyronie's disease can cause erectile dysfunction (ED) and painful intercourse, as well as anxiety and stress.

About 1 in 100 men in the United States have been diagnosed with Peyronie's, but based on reviews of reported symptoms, some researchers postulate that as many as 1 in 10 men could be living with it undiagnosed. Although Peyronie's disease can affect men at any age, it is most common in men older than 40.

The symptoms of Peyronie's can be managed, but the disease rarely goes away on its own. If you think you may have Peyronie's disease, talk to your doctor so you can start treatment immediately.
