Because of this, the prepuce is the shortest and weakest part of the penis on the foreskin.
It is attached to the glans in a flat band and has weak tissue, poor elasticity and ductility. When the penis is in an erect state, the tension on the tether is greatest. When the penile foreskin is pulled strongly from the glans to the root of the penis, the force on the penile foreskin is uneven and the penile tether is the main stress point, so it is easily torn.
