Whilst the reason for Peyronie’s disease isn’t recognised for sure, certain doctors speculate that the curvature can form as a consequence of trauma to the penis. An injury may result in indirect injury and microbleeding. As the penis heals, some development factors are not regulated, creating an exceptional measure of scar tissue to build.
Whilst it was formerly believed that this could happen during boisterous sex, that opinion is rarer of late.
How the penis is constructed
The penis is composed of 3 tubelike cavities. The two on top are known as the corpus cavernosa, and the lower one on is the corpus spongiosum, which holds the urethra tube. The two top corporal cavities enlarge to snare and contain the blood that creates an erection in the male penis. The bottom body, corpus spongiosum, operates principally for passing urine. All of the corporal bodies are encircled by a flexible covering known as the tunica albuginea.
On top of the two corporal cavernosa are the superficial nerves and blood vessels of the penis.
What causes the penis to curve?
In Peyronie’s disease, the flexible tissue of the tunica is substituted by scar tissue. Usually, in penile erection the flexible tissue of the penis enlarges and stretches symmetrically, leading to a straight erection. As the plaque is not elasticated, but quite hard, it does not stretch during an erection.
The disease begins as a little bump or constriction on the shaft of the penis under the foreskin, which builds to create a flat deposit that’s occasionally as big as the width of a large coin. This plaque occupies and substitutes the flexible covering of the penis with inflexible tissueSo once a man with Peyronie’s gains an erection, the plaque does not enlarge, and therefore this causes the erect penis to curve.
