An erection occurs when your imagination or one or more of the senses (vision, hearing, touch, smell, taste) are stimulated and you become aroused. Your central nervous system sends nerve impulses that increase blood flow to your penis. The blood fills the spongy chambers (corpora cavernosa) in the penis, causing them to expand and become rigid. The veins that would normally drain blood from the penis are constricted, trapping the blood inside and maintaining the erection.

An influx of blood to the penis.
