The only way to correct penile curvature is surgical correction, but it is not necessary to correct minor curvature. Many people have different degrees of curvature, which is mainly caused by the uneven development of the corpus cavernosum. However, it is normal to bend upward, and it will not have any influence, and bending left and right will not affect future sexual life. There is no need to correct it, only if it is completely serious. You take a standing position. After the penis is erect, the angle with the lower abdomen is below 90 degrees. If it reaches an angle above 120 degrees, it can be considered for correction. Try not to have an operation, after all, it is a knife on JJ. There are still some risks.
