What are the causes of penile curvature?

Patient's question:

What is the reason for the curvature of my penis?
This is causing me a lot of distress.
Please help me!!
How can it be treated.

Doctor's answer:

Actually, many healthy and normal men have slight bending of the penis to the side or up and down when erect, but it is not severe.
Many developing boys discover that their penis bends at various angles when erect. This can cause embarrassment, shyness, or even make them introverted, leading them to avoid dating or believe they will never have normal sexual relationships or intimacy.
In fact, penile curvature is medically known as "abnormal corpus cavernosum tunica albuginea," where certain parts of the tunica albuginea are thicker, pulling the penis to the other side. For example, if the right corpus cavernosum tunica albuginea is thicker, the penis will bend to the left. Why does this happen? Some assume it is due to wearing tight pants during adolescence or prolonged abnormal bending of the penis; however, there is no actual evidence. Clinically, the corpus cavernosum tunica albuginea shows no scars or hard lumps and appears normal at rest, with curvature only noticeable during erection. The degree and direction of curvature must be observed by injecting medication to induce erection or by having the patient take photos of the erect penis from various angles at home for the final diagnosis of whether surgery is needed.
The surgical method for penile curvature is actually not difficult. First, the foreskin is retracted, and medication is injected or saline is infused to induce erection, allowing observation of the curved penis. Then, excess tunica albuginea is sutured and tied tightly with non-absorbable sutures to gradually correct the curvature. This process can be repeated several times to fully straighten the penis. Most patients have an erection that cannot stand upright or be parallel to the ground before surgery, but after the procedure, the fully erect penis can even exceed the horizontal line of the ground, reaching the abdomen. This can be observed on the operating table to ensure the correction is satisfactory.
