How does one achieve erection ?
The penis contains spongy and cylindrical compartments (called the corpora cavernosa), which stretch along the length of the penis and are surrounded by a membrane (called the tunica albuginea). The spongy tissue contains muscles, blood spaces, veins, and arteries. The urinary canal (urethra), in which the urine and the ejaculate (semen) flows, pass along the underside of these spongy cylinders.
When one is sexually aroused by physical or psychological means there is gush of blood into the open spaces of the spongy cylinders. The accumulated blood generates pressure inside these spongy cylinders causing the penis to expand (erection). The outer membrane helps to trap the blood in the cylindrical compartment in that way aiding in sustaining erection. After the ejaculation, muscles in the penis contract, stopping the inflow of blood and opening outflow channels, making the penis flaccid.
