The visible parts are the penis and the scrotum. The penis is the external sex organ of the male through which both urine and semen pass. The penis transfers sperm to the woman's body during sexual intercourse and is a duct for the disposal of fluid waste. The penis becomes erect during sexual excitement, because extra blood is pumped into spongy tissues, resulting in enlargement and hardening which allows penetration into the female organ.
Inside the body are the prostate gland and tubes, which link the system together. The prostate gland is a solid, chestnut-shaped organ surrounding the first part of the urethra (the tube which carries the urine and semen) in the male. The urethra functions both as a urinary canal and a passageway for cells and secretions from various reproductive organs. The male organs produce and transfer sperm to the female for fertilization.
