The male reproductive system enables a man to have sexual intercourse and to fertilize ova (eggs) with sperm (male sex cells). Sperm, along with male sex hormones, are produced in the "testes," a pair of oval-shaped glands which are suspended in a pouch called the scrotum. The sexual organs of the male are partly visible and partly hidden within the body. The visible parts are the penis and the scrotum. Inside the body are the prostate gland and tubes which link the system together. The male organs produce and transfer sperm to the female for fertilization. The biological symbol for the male comes from a symbol of the shield and spear of Mars, the Roman god of war and aggression.
The reproduction system uses the process of producing a new generation to continue the existence of the species by the fusion of two cells from different individuals; this is achieved in humans by the fusion of one sperm and one ovum (egg). This fusion is called "fertilization" and is achieved by sexual intercourse between a male and female or by artificial insemination. The male body is designed to allow the manufacture, storage and transfer of male sex cells (or sperm). The female body is designed to manufacture, store and release eggs (ova). The creation of human life is a miracle to behold as two tiny cells - the sperm and the ovum - fuse to form a new cell which, after fertilization, resides in the female womb. Nine months later, a fully- formed, breathing, living human being in tiny replica is born.
