How penis enlargement works

Penis is made up of 3 main areas, 2 large chambers on the top (The technical term for this is the Corpora Cavernosa) and 1 smaller chamber on the bottom (the Corpus Spongiosum).

When we gain an erection, the penis fills with blood, filling these three chambers. The Corpus Spongiosum is the chamber used mainly when we urinate and ejaculate. The Corpora Cavernosa however, is the main blood holding chamber of the penis. This is where 90% of all blood is retained each and every time we gain an erection.

Penis size is limited in both length and width, by the maximum in which the Corpora Cavernosa can fill with blood. Simply put, this means it is impossible for penis to get bigger by itself, as the blood which fills the penis is already filling the maximum size of the Corpora Cavernosa.
