Circumcision does not affect erection.
The erection mechanism of the penis is when the brain produces sexual excitement, produce corresponding electrical signals to reach the penis, resulting in the opening of the cavernous arteries of the penis, a large amount of blood into the penis, the enlarged penis and oppressed the returning veins, resulting in the venous return is not good, so the penis continues to be erected for a long time.
The foreskin is the penile skin that covers the surface of the glans, and mainly plays the role of protecting the penis and glans, and the foreskin does not contain nerves and blood vessels that affect erection, so circumcision will not affect erection.
If patients need to undergo circumcision surgery, it is recommended to go to a regular medical institution to be operated by a professional doctor to reduce the risk of surgery.
