Sexual anatomy

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

• Male: penis(notably the glans penisand foreskin), prepuce, testicles, scrotum, prostate, seminal vesicles, epididymis, Cowper's glands
• Female: vulva(notably the clitorisand labia), vagina, cervix, 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 anusfor either sex, the prepuce, the breasts(especially the nipples) for females, and the nipplesfor males.

The Latinterm 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 penisand 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 testesor ovariesin humans.

Organs of sexual anatomy originate from a common anlageand differentiate into male or female sex organs. The SRYgene, located on the Y chromosomeand encoding the testis determining factor, decides the direction of this differentiation. Each sexual organ in one sex has a homologouscounterpart in the other one. See a list of homologues of the human reproductive system.
