Sperm producing structures

Semen , also called seminal fluid , fluid that is emitted from the male reproductive tract and that contains sperm cells, which are capable of fertilizing the female eggs. Semen also contains other liquids, known as seminal plasma , which help to keep the sperm cells viable. In the sexually mature human male, sperm cells are produced by the testes singular, testis ; they constitute only about 2 to 5 percent of the total semen volume. As sperm travel through the male reproductive tract, they are bathed in fluids produced and secreted by the various tubules and glands of the reproductive system. After emerging from the testes, sperm are stored in the epididymis , in which secretions of potassium, sodium, and glycerylphosphorylcholine an energy source for sperm are contributed to the sperm cells. Sperm mature in the epididymis. They then pass through a long tube, called the ductus deferens , or vas deferens, to another storage area, the ampulla.

Anatomy and Physiology of the Male Reproductive System – Anatomy and Physiology

Sperm cells are gametes sex cells that are produced in the testicular organ gonad of male human beings and animals. Like the female gamete Oocyte , sperm cells carry a total of 23 chromosomes that are a result of a process known as meiosis. In both animals and human beings, among many other organisms, these cells are involved in the sexual mode of reproduction which involves the interaction of male and female gametes. The general morphology of sperm cells consists of the following parts:. Before looking at the structure and function of sperm cells, it is important to understand the process involved in their production spermatogenesis.

Sperm release pathway

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.

Sperm is the male reproductive cell. In the types of sexual reproduction known as anisogamy and its subtype oogamy , there is a marked difference in the size of the gametes with the smaller one being termed the "male" or sperm cell. A uniflagellar sperm cell that is motile is referred to as a spermatozoon , whereas a non-motile sperm cell is referred to as a spermatium.
