MICROANATOMY

Detailed explanation-1: -What is an erection? An erection is when your penis becomes hard and enlarged from an increase in blood flow. This increase in blood flow makes your penis stand up and away from your body (erect). Sexual stimulation or excitement is the typical cause of an erection.

Detailed explanation-2: -A persistent, prolonged erection of the penis that will not go down is called priapism. This unwanted erection may or may not be caused by sexual arousal, is usually very painful and can last for 2 hours or longer. Priapism is a medical emergency. The sooner you treat it, the less risk that the penis will be damaged.

Detailed explanation-3: -From our results we conclude that penile erection can be subdivided in 5 phases: (1) latent-, (2) tumescence-, (3) erection-, (4) rigidity-and (5) detumescence phase.
