Human reproductive organ during sexual intercourse

The external structures of the male reproductive system are the penis, the scrotum and the testicles. Penis — The penis is the male organ for sexual intercourse. It has three parts: the root, which attaches to the wall of the abdomen; the body, or shaft; and the glans, which is the cone-shaped end of the penis. The glans, which also is called the head of the penis, is covered with a loose layer of skin called foreskin. This skin is sometimes removed in a procedure called circumcision. The opening of the urethra, the tube that transports semen and urine, is at the tip of the glans penis.

22.2: Introduction to the Reproductive System

The human reproductive system functions to produce human offspring, with the male providing sperm and the female providing the ovum. While the ultimate purpose of the human reproductive system is to produce offspring, the proximate purpose is to produce pleasure and induce bonding. This can be seen in our closest relatives, the bonobo chimpanzees, who have sex for a wide variety of reasons including pleasure, bonding, and alleviating tension in addition to producing offspring. The reproductive system or genital system is a set of organs within an organism that work together to produce offspring. Many non-living substances, such as fluids, hormones, and pheromones, are important accessories to the reproductive system.

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.
