The key male reproductive organs include the testes, epididymis, urethra, vas deferens, prostate gland, seminal vesicle, and penis. The testes are composed of coiled structures called seminiferous tubules, which are the sites of sperm production. The structure on top of the seminiferous tubules in the testes is the epididymis. The sperm migrate from of the seminiferous tubules to the epididymis. Within the epididymis, the sperm mature while they are stored in this structure.

Reproductive System: Facts, Functions and Diseases | Live Science

The male reproductive system consists of a number of sex organs that play a role in the process of human reproduction. These organs are located on the outside of the body and within the pelvis. The main male sex organs are the penis and the testicles which produce semen and sperm , which, as part of sexual intercourse , fertilize an ovum in the female's body; the fertilized ovum zygote develops into a fetus , which is later born as an infant. The corresponding system in females is the female reproductive system. The penis is the male intromittent organ. It has a long shaft and an enlarged bulbous-shaped tip called the glans penis , which supports and is protected by the foreskin. When the male becomes sexually aroused , the penis becomes erect and ready for sexual activity.

In simple terms, reproduction is the process by which organisms create descendants. This miracle is a characteristic that all living things have in common and sets them apart from nonliving things. But even though the reproductive system is essential to keeping a species alive, it is not essential to keeping an individual alive. In human reproduction, two kinds of sex cells or gametes are involved. Sperm, the male gamete, and a secondary oocyte along with first polar body and corona radiata , the male gamete must meet in the female reproductive system to create a new individual.
