Vagina

Vagina The vagina is the female internal sex organ that begins on the outside at the vaginal opening and extends about three to five inches inside, ending at the cervix, or neck of the uterus (womb). Three Layers of Tissue The vagina consists of three layers of tissue. The mucosa is the layer on the surface that can be touched. It consists of mucous membranes and is a surface similar to the lining of the mouth. Unlike the smooth surface of the mouth lining, the vagina contains folds or wrinkles. The next layer of tissue is a layer of muscle, concentrated mostly around the outer third of the vagina. The third, innermost layer consists of fibrous tissue that connects to other anatomical structures. In the sexually unstimulated state, the vagina is shaped like a flattened tube, the sides of which are collapsed on each other. It is not a continually open space, or "hole" as often thought by both women and men. It is a potential space. Because of its muscular tissue, the vagina ha

Menstruation

Menstruation   Menstruation refers to the periodic vaginal discharge of blood and bodily cells that are shed from the lining of a woman's uterus. Menstruation begins at puberty and marks the onset of a woman's capacity to bear children, although other health factors may limit this capacity. Menstruation usually begins between 10 and 16 years of age, depending on a variety of factors, including the young woman's general health, nutritional status, and body weight relative to height. Menstruation continues approximately once a month until a woman is about 45 to 50 years of age, again depending on health and other influences. The end of a woman's ability to menstruate is called menopause and it marks the completion of a woman's childbearing years. Length of the Menstrual Cycle The average length of the menstrual cycle is 28 days, but ranges from 21 to 40 days. The length of the cycle may also vary for a woman during different phases of life, and even from one

Menopause

Menopause   Menopause is a natural physical transition that every woman experiences as she ages. It is often loosely defined as the final cessation of menstruation in a woman's life. This implies an abrupt and complete transition, although the actual process is typically quite gradual. While most women undergo this change between the ages of 48 and 52, some women stop menstruating as young as their late thirties or early forties, and others continue to menstruate into their mid-fifties. The process leading up to menopause begins with a slow-down in the function of the ovaries, generally about five years before the last menstrual period, and additional physical and emotional changes continue for several years after the last period. What Happens during Menopause During this time, there is a change in the hormonal balance, with a decrease in the amount of estrogen produced by the ovaries. Finally, there is such a low level of estrogen production that periods become irregula

Breasts

Breasts   Breasts are part of the anatomy of both females and males. On the inside, a woman's breast is made up of about 15-25 milk-producing sacs called milk glands, which are connected to milk ducts that converge inside the nipple. The remainder of the internal breast is composed of fatty tissue and fibrous connective tissues that bind the breast together and give it shape. On the outside of the breast there are nipples. Nipples, like all other anatomical structures, vary in appearance from woman to woman. They may stick out prominently, they may have a flattened appearance, they may be set a bit deeper in the breast, or they can be inverted. Each nipple is supplied with many nerve endings, which make it particularly sensitive to touch. There are thin muscle fibers in nipples that enable them to become erect. The darker pigmented area around each nipple is called the areola (plural: areolae). The size and color of the areolae vary from woman to woman. This area can be

Virginity

Virginity Virginity is the state of never having had sexual intercourse. It is viewed positively or negatively depending on one's gender, one's age, one's culture and one's own personal beliefs and attitudes. In some cultures virginity has no special significance, and young people, of both sexes, engage in coitus very early and there is no special status associated with not doing so. In others, virginity is required of both sexes, and in many it is required of women only. Violation may result in severe punishment. For example, proving a bride's virginity became a public matter wherein the bed sheets used by the couple on their wedding night were hung out the window for the wedding guests to view. A bloodstained sheet was a sign that the groom penetrated the bride's intact hymen, causing it to bleed. Though not medically true, the theory was that the hymen would be unbroken if she were still a virgin. Retaining Virginity: An Important Goal In some North America
