The Female Sexual Organs - Summary

The clitoris, the small knob of tissue at the front of the vulva, is the seat of female sexual excitement. This organ is the female counterpart to the glans penis and corpus spongiosum of the male.

It has the same sensitive nerve endings connected to the "pleasure centers" of the brain as does the penis, and its sole function is to transmit sexual pleasure and make any female come. It is partially covered by a fold of skin called the clitoral hood which is analogous to the male foreskin.

Surrounding the clitoris and the vaginal opening are two folds of skin known as the labia (Latin for "lips"). The labia majora, or outer "lips," are fleshy and covered with pubic hair, while the labia minora, or inner "lips," are thin and hairless. The labia are erotically sensitive to touch.

Below the clitoris is a small, almost invisible opening connected to the bladder by the short female urethra. The female urethra, unlike that of the male, has only one function: to conduct urine from the bladder. It has nothing to do with reproduction.

However, it may have a role to play in female orgasm. Recent research has shown that the female urethra is surrounded by prostate-like tissue, the so-called female prostate or Skene's glands, which may produce ejaculate during sexual arousal.

The stimulation of the G spot during sexual intercourse appears to be basically a way of stimulating the female prostate gland.

Between the urethra and anus is the entrance to the vagina, guarded by a ring of muscles. The vagina at its entrance is very sensitive. Inside the vaginal entrance is the hymen, a sheet of skin like tissue which partially closes off the vaginal opening in virgins. Penile penetration ruptures the hymen. It then wears away completely before long.

There is a wide range of normal variation in the thickness and blood supply of the hymen. In some cases it is so thin that it is not even noticed at the time of the first intercourse.

In other cases it is a little thicker, so that rupturing it produces a slight pain and spills a few drops of blood. Occasionally it is so strong and thick that it must be removed by a surgeon before intercourse is comfortable or even possible.

The labia, the clitoris, and the entrance of the vagina are known collectively as the vulva. Again, these organs are extremely sensitive. The vagina connects the external genitals with the internal reproductive organs.

The vaginal barrel ends near the cervix which is the entrance for the sperm. The fallopian tubes arise out of the uterus and open like a funnel near the ovaries where they are ready to catch the egg as it ruptures out of the surface of the ovary during ovulation.

The vagina itself is a thin, collapsible, elastic tube made of sheets of muscle. Inside, the vagina is lined with smooth, moist cells very much like the inside of the mouth. It provides a passage between the vulva which is open to the external world and the uterus, an internal organ.

The vagina is designed to allow the sperm to make connection with the female's egg, which is carried inside her body. The vagina is so elastic that it can stretch to accommodate a baby's head during birth, and then return to its normal shape.

Because of this elasticity the normal vagina can accommodate any penis whether it is small or large. It is not too large to provide friction or too small to allow entry. Vaginal flexibility is another reason why penis size is not especially important in sexual functioning.

The one-third of the lining of the vagina nearest the vaginal opening is very sensitive not only to pressure but also to touch. Contact produces reflex changes and also transmits pleasurable erotic sensations.

 These sensations have a different quality from the sensations felt when the clitoris is stimulated. Vaginal orgasm is important for complete sexual pleasure for a woman.

The inner two-thirds of the vagina are not especially sensitive to touch although the surrounding pelvic tissues are sensitive to pressure.

Thus during intercourse, the female feels the pressure of the penis deep in her pelvis, and also its in and out motions near the sensitive vaginal entrance.

The sensation of being penetrated by the erect penis is considered by many women to be highly enjoyable, and essential to sexual satisfaction.

Other women find less pleasure in penetration. Some actually feel only mild sensations. This is especially true if a man ejaculates too soon, in which case a program to stop premature ejaculation may help enormously.

The clitoris and G spot are the most erotically sensitive parts of a woman's body. Most women find clitoral stimulation far more erotic than vaginal penetration, but the majority of women enjoy both.

Again, stimulation of the vagina feels good and can produce orgasm, though it's more commonly produced by clitoral stimulation. For a couple to fully enjoy sex, it is essential to find a sex position which suits the angle of the penetrating penis and the receiving vagina.

The skin and glands located in and around the vulva secrete chemicals called pheromones which have a distinctive odor. This normal genital odor should not be confused with the odors caused by lack of cleanliness or infections of the vagina.

In many animals the female genital odor acts as an intensely erotic stimulus for the male. Humans seem to have mixed feelings about genital odors.

Some normal persons find them attractive and other equally normal persons find them somewhat repugnant.

Men are often repelled by the female genital odors at first, then learn to accept them, and finally come to enjoy them. It is often the same story with women's attitude toward semen. Most women are repelled by semen at first, but later some learn to accept and even to enjoy its sight, odor, and taste.

However, there are some perfectly normal women who do not want to have any contact with semen except when they receive it in the vagina.

The Internal Female Reproductive Organs

The internal female reproductive organs are all contained in the pelvis, and consist of the ovaries, the uterus, and the fallopian tubes.

The ovaries are the female gonads or sex glands. They develop from the same material that produces the testes and they too have dual functions: the production of eggs or ova, and the secretion of female hormones.

The ovaries have many immature egg cells nestling under their surface. Each month one matures and breaks loose from the ovary and travels down the fallopian tubes to the uterus.

The ovaries produce two female hormones, estrogen and progesterone. Estrogen causes the growth and development of the female genitals and reproductive organs. It also produces female secondary sexual characteristics such as breasts and a female hair distribution. Progesterone is the "pregnancy hormone."

The other female reproductive organs are designed to protect the egg and to provide a favorable place for fertilization and, if it should be fertilized, to shelter and nourish the unborn baby.

In its non-pregnant state, the uterus, or womb, is a thick, muscular organ, pear-shaped, about the size of a fist, and lined with layers of cells that are very sensitive to female hormones. It opens into the vagina at the cervix, where the semen is deposited during intercourse.

Thousands of immature oocytes, which have not even completed their first meiotic division, lie dormant beneath the surface of the ovary. At the beginning of a menstrual cycle, the pituitary gland secretes a follicle stimulating hormone (FSH) which causes several oocytes to complete their first meiotic division and to begin to grow, nourished by the follicle cells which surround them.

The follicle cells also produce the hormone estrogen. The oocytes grow within little blisters called follicles, and at some point between the twelfth and fourteenth day of the menstrual cycle, the pituitary sends another hormone, luteinizing hormone (LH), which causes ovulation, or the rupture of the ovum out from the surface of the ovary.

After ovulation, the scar, or corpus luteum continues to produce estrogen, but now also begins to manufacture and secrete a second female hormone, progesterone during the second half of the menstrual cycle. If fertilization occurs, the corpus luteum persists and continues to produce progesterone. If the woman does not become pregnant, the cycle begins anew, and the corpus luteum is reabsorbed into the body in a few weeks.

The ovaries are held in place by strong ligaments. As the ovum pops out of the surface of the ovary it is picked up by the octopus-like opening of the fallopian tube. If fertilization occurs, it usually occurs as sperm that have entered the reproductive tract via the vagina encounter the egg as it travels down this tube.

The egg continues to travel toward the uterus after fertilization, although by this time it is already rapidly dividing. When it reaches the uterus it implants itself into the thick endometrium or lining, while it waits for the formation of the placenta.

The uterus is shown in its small, thick non-pregnant state, but of course, it extends greatly as the baby grows. During labor, the muscles of the uterus contract so strongly that they push the baby out through the vagina.


Under the influence of estrogen, the female's breast tissue and nipples grow. Breast growth begins during adolescence when the body manufactures larger amounts of estrogen.

We have already mentioned that the breasts are composed of glands which are capable of taking nutritive material out of the mother's blood stream and out of this, manufacturing milk which a newborn baby with an immature digestive system can absorb. The milk is conducted through little ducts which all converge in the nipple.

The baby obtains milk by sucking on the nipple. The sucking reflex is necessary for an infant's survival and is present at birth. A woman's breasts are designed to provide nourishment for the infant.

They enlarge during pregnancy and secrete milk right after the baby is born. They will go on producing milk as long as the baby suckles. Milk production is controlled by a hormone secreted by the pituitary gland.

The breasts, and especially the nipples, are also sexual organs in that they arouse the male and give pleasure to the female when they are stimulated.

They are erogenous zones - that is, touching them feels good and produces sexual pleasure. Having their nipples stimulated is also arousing for some men.

Normal breasts vary widely in size and shape. Unless there is a hormone problem, which is uncommon, female breast sizes range from A to triple D, and all are physically normal.

This is determined by heredity, and there is not much you can do to change them. Different societies and different males define certain sizes and shapes of breast as attractive or as unattractive.

In some societies, for example, women with large and even pendulous breasts are much admired, while other societies idealize slim women with small, firm breasts. There is a wide range of opinion in our society as to what shape and size breast is most attractive.

Typically in our society the large breasted woman is considered sexy, and large breasted women appear in erotic magazines as the ideal. However, most fashions are designed for women with small breasts, so that it is easier for an A and B cup woman to find attractive clothes than it is for the C and D cupper.

It is not surprising that girls tend to have strong feelings about the size and shape of their breasts. Worry that one's breasts are too small or too large causes many a good deal of misery. Small breasted girls wear padded bras and large breasted girls attempt to hide their bosoms by hunching their shoulders and by wearing baggy clothes.

Indeed, some women are so ashamed of their breasts that it interferes with their enjoyment of sex, because they will not let a man see them unclothed or feel their breasts.

A woman's breasts actually are often important to a man's sexual response, but men vary as widely in their preferences as breasts do in their sizes. Some men find tiny breasts more exciting, while others are only aroused by large, full breasts.

But a secure person knows that he or she won't be loved by everybody and doesn't worry too much about anatomy: be it height or breast size or penis size.

It is true some men will not be attracted to you unless you are tall or short, have big or small breasts or slim hips or full buttocks. But you become beautiful and exciting no matter what your bra size is if you have a romantic relationship.

And if you love him you won't notice the size of his penis. Physical attributes are important; one should try to look good, smell good, and sound good. But appearance can become an obsession where a minor pimple can ruin your whole day.

How you look is important mainly in the beginning of a relationship. Once love is established, appearance becomes relatively unimportant.

Sometimes a girl's breasts develop unevenly, that is, one breast is much larger than the other, or sometimes they really fail to develop at all, or they can grow grotesquely large. Such problems are true abnormalities, and they need not cause a lifetime of misery because they can be corrected by plastic surgery.

The breast is made up of glands, fatty tissue lying between the glands, and connective tissue which holds the glands and fat together, giving the breast its shape. The glands are connected to ducts which all come together at the nipple.

The breast is a sexual organ in that it is sensitive to erotic stimulation, and of course, it is also the organ of nourishment which supplies the immature infant with simple food until he can find and digest his own food. The breast glands are very sensitive to sex hormones.

Thus, they develop during puberty when the ovaries start to produce large amounts of estrogen, and they turn into highly efficient "milk factories" shortly after the birth of the baby triggers the release of special pituitary hormones.
