The male reproductive system
The male reproductive system includes the testes (say "test-eez"), prostate glands, sperm ducts, urethra and penis (P).
During mating, sperm cells that have been released pass through the sperm ducts.
There are two testes (one of them is called a testis). These are held in place by the scrotum (scrotal sacks). The scrotum is a bag of tough skin. The job of the testes is to produce millions of male cells called sperms and also to make male reproductive hormones. This is a simple diagram of how a sperm cell looks under a microscope. Sperm cells look a lot like tadpoles (under a microscope). During puberty, a boy’s hormones affect the way his body develops.
The job of the prostate gland is to secrete prostate fluid, one of the components of semen. The mixture of sperm and fluids is called semen. The muscles of the prostate gland also help propel this seminal fluid through the urethra and into the female reproductive organ during ejaculation .
This is the tube inside the male organ that carries urine or semen. It is the continuing part of the sperm duct.
This is that ‘thing’ hanging in front of every male which he pees with. The size of the organ differs a lot for growing boys because they develop differently. An erect one for an adult man may be about 5.7inches in length (average). The job of the 'P' is to pass urine out of the man's body and to pass semen into the female organ during mating.
