Sexual intercourse , also called coitus , or copulation , reproductive act in which the male reproductive organ in humans and other higher animals enters the female reproductive tract. If the reproductive act is complete, sperm cells are passed from the male body into the female, in the process fertilizing the female egg and forming a new organism. In some vertebrates, such as fish , eggs are laid outside of the body and fertilized externally. To accomplish internal copulation certain body and organic adaptations are necessary. In the human male, the penis serves both excretory and reproductive functions. During intercourse, the blood flow is temporarily increased and trapped in the penis so that it becomes enlarged and elevated, a condition known as erection.
