Testes Definition Anatomy

The scrotum hangs outside the body in the front of the pelvic region near the upper thighs. The testes are responsible for the production of sperm cells and the male sex hormone testosterone.

Testes the organ of the male animal.

Testes definition anatomy. The testes also called testicles are two oval shaped organs in the male reproductive system. The functions of the testes are to produce both sperm and androgens primarily testosterone. A typically paired male reproductive gland that produces sperm and secretes testosterone and that in most mammals is contained within the scrotum at sexual maturity.

The testes or testicles are part of the male genitalia or sexual reproductive organ. These hormones control the development of the reproductive organs and other male characteristics such as body and facial hair low voice and wide shoulders. It is a structure that is ovoid in shape and between four to six centimeters in length.

Whereas sperm production is controlled both by the anterior pituitary follicle stimulating hormone and gonadal testosterone. Each is an ovoid body about 4 cm long and 2 to 25 cm in width and thickness enclosed within a dense inelastic fibrous tunica albuginea. Theyre contained in a sac of skin called the scrotum.

In most vertebrates the testes are contained inside the body. About 2 percent of newborn boys have an undescended testis at birth but this condition often corrects itself by the age of three months. The primary reproductive organ of male animals in which sperm and the male sex hormones androgens are produced.

Testosterone release is controlled by the anterior pituitary luteinizing hormone. Anatomy of the testes. The testis or testicle contains the long coiled seminiferous tubules in which the spermatozoa are formed.

These bilateral though not always symmetrical anatomical structures are the site of sperm production. Medical definition of testis. The testis is divided into numerous lobules separated by septa each lobule containing one to three seminiferous tubules within which the spermatozoa are produced by meiosis.

Testicle or testis is the male reproductive gland or gonad in all animals including humans. It is homologous to the female ovary. The testes are formed in the abdominal cavity and descend into the scrotum during the seventh month of gestation when they are stimulated by androgens.

Testis commonly known as the testicles are a pair of ovoid glandular organs that are central to the function of the male reproductive system. In many mammals however the testes are enclosed in an external scrotum. Also known as testicle.

Between the tubules are cells that secrete testosterone and other masculinizing steroid hormones and oestrogens. The testes produce and store sperm and are also the bodys main source of male hormones such as testosterone.
