It is not a myth but an actual condition that might happen when it is erect and experiences a certain amount of force. However, since this organ doesn't contain actual bones, the effect of its fracture differs from that of an arm or leg fracture?
What is penis fracture?
Penis fracture is a condition where an erect penis suffers a fracture. An erect penis is filled with blood, in this condition, if it is bent forcefully or suddenly, it can suffer a fracture. The penis consists of two large cylinders and one smaller cylinder; during erection blood rushes to the two larger cylinders inflating them thus turning the penis hard and erect. In this state, if it faces a sudden force it can cause damage to the penis.
The symptoms of penis fracture are-
1. A popping or cracking sound in case of sudden trauma
2. Loss of erection almost immediately
3. Feeling of pain in the affected area
4. Bruising of the area
5. In some cases the urethra can get damaged, causing blood to come out of it
In the case of penis fracture, one should seek medical advice immediately. If the condition is not treated then it can result in severe complications. A physical exam followed by exams like MRI or urethrogram are used to diagnose the problem. Surgery is mostly recommended to repair the penis after the diagnosis and it should not be delayed for long. In case the surgery is delayed, scarring occurs and it can result in erectile dysfunction. If you wish to discuss any specific problem, you can consult a sexologist.
