A sex organ or reproductive organ is any part of an animal's body that is involved in sexual reproduction. The reproductive organs together constitute the reproductive system. The testis in the male, and the ovary in the female, are called the primary sex organs. Mosses , ferns , and some similar plants have gametangia for reproductive organs, which are part of the gametophyte.
Female External Genital Organs

Collectively, these parts are called the vulva. Rich with nerves, the vulva can provide sexual pleasure when properly stimulated. The vagina is a muscular tube about three to four inches long that ends the birth canal. The vaginal opening is visible from the outside but it is protected by the labia when a woman stands and during most activities. The labia majora are two folds of skin that extend from the front of the vaginal opening to the back of it. The outer surfaces of the folds have darker-colored skin and stronger hairs, while the inner folds are smoother.

The external genital organs include the mons pubis, labia majora, labia minora, Bartholin glands, and clitoris. The area containing these organs is called the vulva. Protecting the internal genital organs from infectious organisms. The mons pubis is a rounded mound of fatty tissue that covers the pubic bone.
There are also multiple non-genital peripheral anatomic structures involved in female sexual responses such as salivary and sweat glands, cutaneous blood vessels and nipples. The vagina consists of a tube of autonomically-innervated smooth muscle longitudinal outer, inner circular layer lined by stratified squamous epithelium and a sub-dermal layer rich in capillaries. The vaginal wall consists of an inner glandular mucous type stratified squamous cell epithelium supported by a thick lamina propia. This epithelium undergoes hormone-related cyclical changes including slight keratinization of the superficial cells during the menstrual cycle. Deep to the epithelium lies the smooth muscles of the muscularis.
