Penile erection is upward and outward, but there will be bending, which can be divided into physiological bending and pathological bending. The penis consists of two sponges. Penile erection is the result of sponge congestion. However, due to the different sizes of cavernous body during congestion, the penis tends to bend in the direction of congestion, and most men bend and deflect in a certain direction to varying degrees. This is physiological curvature, which generally has no effect on sexual life and does not need treatment. A few men suffer from congenital short prepuce frenulum. Or excessive circumcision, or local scars caused by penis trauma or infection. When the penis is erect, the penis can be obviously bent. Generally, slight bending has no effect on sexual life and does not require treatment. If severe bending has an impact on sexual life, do a simple penis correction operation to straighten the bent penis. Surgery usually uses local anesthesia, which takes about an hour, and you can go to work normally without obvious side effects.
