Circumcision and prepuce are a congenital evolutionary defect disorder due to a genetic defect in humans. Circumcision does not necessarily have a foreskin, but a foreskin can have a circumcision.
The Tyson’s gland, located between the inner foreskin and the glans, secretes a “selective genetic small-molecule protein gene” that scientists have named the OGN factor.
From the age of 3, the Tyson’s gland begins to secrete the OGN factor, which causes the adhesion fibers between the foreskin and the glans to be naturally absorbed by the body, removing the biological force between the foreskin and the glans. By about 7 years of age, the glans and foreskin naturally separate and the urethra and glans are exposed outside the foreskin. However, due to a genetic defect in humans, about 39% of men worldwide have Tyson’s gland that does not secrete the OGN factor properly, causing the foreskin and the head of the penis to be unable to separate or even adhere, and the glans cannot be fully exposed, resulting in symptoms of phimosis and prepuce.
