The penis contains three so-called ‘corpora’ – sponge-like columns of erectile tissue – that fill with blood during an erection, making them expand and become hard.
Viewed from above, a corpora cavernosum stretches along each sides of the penis, the third, which also includes the glans, is situated below and between them. If one corpus or section is shorter than the others, it causes the penis to curve towards the shortened side.
There are two types of congenital penis curvature: it is either present at birth or develops during puberty (atrophy of the penis erectile tissue).
If your penile curvature is severe and making intercourse difficult or impossible, then penis surgery is likely to be recommended. The procedure gives good results in straighten bent penis whether the cause is Peyronie’s disease or congenital curvature.
There is a serious risk involved with surgery though, i.e. risk of erectile dysfunction or becoming impotent, so penis surgery should only be undertaking in the most severe cases.
