Sex organ

From open-encyclopedia.com - the free encyclopedia.

A sex organ, or primary sexual characteristic, narrowly defined, is any of those parts of the body (which are not always bodily organs according to the strict definition) which are involved in sexual reproduction and constitute the reproductive system in an complex organism; namely:

• Male: penis (notably the glans), testicles, scrotum, prostate, seminal vesicles, epididymis, Cowper's glands
• Female: vulva (notably the clitoris), vagina (notably the cervix), labia, uterus, Fallopian tubes, ovaries, Skene's glands, Bartholin's glands.

More generally and popularly, the term sex organ refers to any part of the body involved in erotic pleasure. The larger list would certainly include the anus for either sex, the breasts (especially the nipples) for females, and possibly the nipples for males.

The Latin term genitalia is used to describe the sex organs, and in the English language this term and genital area are most often used to describe the externally visible sex organs or external genitalia: in males the penis and scrotum, in females the vulva. The other parts of the sex organs are called the internal genitalia.

A gonad is a sex organ that produces gametes, specifically the testes or ovaries in humans.

Many parts of human sexual anatomy are homologous between the sexes. For example:
