Tissues in the penis produce enzyme PDE5 which reduces the size of the penis by decreasing the blood supply once the intercourse is done. This helps in reverting back of penis to its original form. But in certain men this enzyme gets increased and the penis remains flaccid even at the time of sustaining an erection. Kamagra Chewable tablet acts by reducing this enzyme amount.
