There is a great deal of variation in the appearance of female genitals.
Much of this variation lies in the significant differences in the size, shape, and color of the labia minora. Though called the smaller lips they can often be of considerable size and may protrude outside the vagina or labia majora.
This variation has also been evidenced in a large display of 400 vulval casts called the ''Great Wall of Vagina'' created by

. This division creates two areas one surrounded by the urethral folds and the other by the anal folds.
These areas become the urogenital triangle and the anal triangle.
The area between the vagina and the anus is known as the clinical perineum.

The labioscrotal swellings (genital swellings or labioscrotal folds) are paired structures in the human embryo that represent the final stage of development of the caudal end of the external genitals before sexual differentiation. In both males a ...
.
Sexual differentiation takes place, and at the end of week 6 in the female, hormones stimulate further development and the genital tubercle bends and forms the clitoris.
The urethral folds form the labia minora and the labioscrotal swellings form the labia majora. At this time the sexes still cannot be distinguished.
The appearance of the external genitalia is similar in male and female embryos until the twelfth week and even then is difficult to distinguish.
The uterovaginal canal or genital canal, forms in the third month of the development of the urogenital system. The lower part of the canal is blocked off by a plate of tissue, the vaginal plate. This tissue develops and lengthens during the third to fifth months and the lower part of the vaginal canal is formed by a process of desquamation or cell shedding. The end of the vaginal canal is blocked off by an endodermal membrane which separates the opening from the vestibule. In the fifth month the membrane degenerates but leaves a remnant called the hymen.

The decreased estrogen affects the mons, the labia, and the vaginal opening and can cause pale, itchy, and sore skin.
Other visible changes are a thinning of the pubic hair, a loss of fat from the labia majora, a thinning of the labia minora, and a narrowing of the vaginal opening. This condition has been renamed by some bodies as the ''genitourinary syndrome of menopause'' as a more comprehensive term.
Function and physiology
The vulva has a major role to play in the reproductive system. It provides entry to, and protection for the uterus, and the right conditions in terms of warmth and moisture that aids in its sexual and reproductive functions. The external organs of the vulva are richly innervated and provide pleasure when properly stimulated. The mons pubis provides cushioning against the pubic bone during
intercourse.
A number of different secretions are associated with the vulva, including

All the women with a large gap stated that they did not experience satisfying pleasure from penile penetration, although some were very sensitive to "precise stroking by the man".
Bonaparte concluded from this an anatomical causal connection between a large CUMD and "vaginal frigidity" explaining why only women with the clitoral glans close to the vagina (so that it is continuously touched by the penis) were able to experience "the highest sexual pleasure" during coitus.
