Sex organ

Sex organ

A sex organ (or reproductive organ) is any part of an organism's body that is involved in sexual reproduction. The reproductive organs together constitute the reproductive system.

Structure

Sex organs are differentiated into male and female varieties. In mammals, the major sex organs include the penis and testes in males, and the vagina, uterus, and ovaries in females.

Male

The male sex organs are part of the reproductive system, consisting primarily of the penis and the testes. The penis is the main part of the external male sex organs, and its main role is to deliver sperm. The testes produce sperm and testosterone.

Female

The female sex organs include the vagina, uterus, and ovaries. The vagina is a canal that joins the cervix to the outside of the body. The uterus, also known as the womb, is a major female hormone-responsive secondary sex organ. The ovaries are small, paired organs that are located near the lateral wall of the pelvic cavity.

Function

The primary function of sex organs is to facilitate sexual reproduction. This involves the production and release of gametes (sperm in males and eggs in females), the fertilization of eggs by sperm, and the nurturing of the developing offspring in females.
