A bent penis during erection can be congenital (Krummerick), but more commonly it is due to acquired scar tissue in the wall of the corpus cavernosum in adult men (Peyronie’s disease).
What is Peyronie’s disease?
Peyronie’s disease is completely benign and affects approximately 5-10 percent of all men, most between the ages of 40 and 55. The condition can have several different causes, such as trauma to the penis or an autoimmune background. In some cases, there is also a comorbidity with diabetes and Dupuytren’s contracture (bent fingers). Some heredity for Peyronie’s disease has also been seen, but in many cases the symptoms come on slowly without any connection to any event, disease or injury.
This condition occurs due to inflammation in the corpus cavernosum, which turns into scar healing within about a year. This leads to the formation of hard spots (plaques) in the penis. At the beginning of the inflammation, the plaques may be tender, but the pain subsides when the inflammation subsides. The plaque prevents the wall of the corpora cavernosa from stretching during erection, causing the penis to bend towards the side where the scar tissue is located.
During erection, the bend is intensified, and it can become difficult, painful or in some cases impossible to have intercourse. Many people also experience psychological effects, which in turn can cause erection difficulties.
Common symptoms of Peyronie’s disease:
- Painful erection at the beginning of the course
- Nodules can be felt in the corpora cavernosa of the penis
- The penis becomes bent during erection
- Other changes in the shape of the penis, such as tapering or an hourglass shape, can cause instability during erection
- Shortening of the penis
- Erectile function may deteriorate and the outer end of the penis often does not become as hard as the part closest to the body
Krummerick
A patient with Krummerick is born with a bent penis, but usually lacks other symptoms. However, the examination and treatment are in principle the same as for Peyronie’s disease.
