Vulva or external genitalia:
Consists of the mons pubis, labia majora, labia minora, clitoris, hymen, vestibule and gland.

Mons Pubis:
The fat-filled cushion that lies over the anterior surface of the symphysis.

Labia Majora:
These are two rounded folds of adipose tissue that are covered with skin and extend downward and backward from the mons pubic. After repeated childbearing, the labia majora become less prominent, and in older women begin to shrivel. Their structure is 6 to 8 cm in lenght, 1-inch in width, and 1 to 2 cm in thickness, and is tapered at the lower extremities.

Labia Minora:
Two flat reddish folds of tissue visible when the labia majora are separated. It is a thick fold of tissue that is moist and reddish in appearance. There are no hair follicles in the labia minora, but there are many sebaceous follicles; a few sweat glands. (These structures are supplied with a variety of nerve endings and are very sensitive.) The labia minora vary greatly in size and shape. They usually are not visible in women who had no childbirth, whereas in multiparous women (women with previous childbirth) it is common for labia minora to project beyond the labia majora.

Clitoris:
The clitoris is the homologue of the penis in women and is located near the superior of the vulva. This erectile organ projects downward between the branched labia minora. The clitoris made of a body (corpus), a gland, and two crura. Rarely the clitoris exceeds 1-inch in length, even in state of erection. The gland, which rarely exceeds l/8th of an inch in diameter, is richly supplied with nerve endings, The clitoris is the principal erogenous organ of women.

Vaginal opening and Hymen:
The vaginal opening varies considerably in size and shape. In virginal women is hidden by labia minora and covered with hymen ring. Some women become more irritated and fear mycosis of the enlarged labia, secondary to exposure of the extra tissue to the underwear or pantyhose. Many women prefer to have the shape of their labia more visually pleasent for their partner.
