The organs which primarily distinguish one sex from the other are the sex organs. It is by the aid of the sex organs that children are begotten and brought into the world, that the race is reproduced and perpetuated. It is for this reason that the sex organs are also called the Reproductive Organs.
The first thing we must do is to become familiar with the structure and location of the sex organs; in other words, we must get a fair idea of their Anatomy.
The female sex organs, also called the reproductive or generative organs, are divided into internal and external. The internal are the most important and consist of: the ovaries, Fallopian tubes, uterus or womb, and vagina. The external sex organs of the female are: the vulva, hymen, and clitoris. Among the external organs are also generally included the mons Veneris and the breasts or mammary glands.
The Ovaries. The ovaries are the essential organs of reproduction. For it is they that generate the eggs, or ova, or ovules, which, after becoming fertilized or fecundated by the spermatozoa of the male, develop into children. Without the ovaries of the female, the same as without the testicles of the male (to which they correspond), no children could be begotten, and the entire human race would quickly disappear from our planet. The ovaries are two in number; they are embedded in the broad ligaments which support the womb in the pelvis, one on each side of the womb. They are of a grayish or whitish pink color, and are about an inch and a half long, three-quarters of an inch wide, and one-third of an inch thick. They weigh from one-eighth to one-quarter of an ounce. Their surface is either smooth or rough and puckered. Think of a large blanched almond and you will have a pretty fair idea of the size and shape of an ovary.
Ovary.
The Fallopian Tubes. The Fallopian tubes (so called from Fallopius, a great anatomist, who discovered them; also called oviducts: egg conductors, because they conduct the eggs from the ovary into the uterus) are two very thin tubes, extending one from each upper angle of the womb to the ovaries; but at their ovarian end they expand into a fringed and trumpet-shaped extremity. The fringes are referred to as fimbria. They are about five inches long and only about one-sixteenth of an inch in diameter; the function of the tubes is to catch the ova as they burst forth from the ovaries and to convey them to the uterus. Taking into consideration the very narrow lumen, or caliber, of the Fallopian tubes, it is easy to understand why even a very slight inflammation is apt to clog them up, to seal their mouths or openings, thus rendering the woman sterile, or incapable of having children. For, if the Fallopian tubes are "clogged" up, the eggs, or ova, have no way of reaching the uterus.
The Greek name for the Fallopian tube is salpinx (salpinx in Greek means tube). An inflammation of the Fallopian tube is therefore called salpingitis. (A salpingitis has the same effect in causing sterility in the female as has an epididymitis in the male.) Salpingectomy is the cutting away of the whole or of a piece of the Fallopian tube (corresponds to vasectomy in the male).

The Uterus. The uterus or womb is the organ in which the fertilized ovum, or egg, grows and develops into a child. It is a hollow muscular organ, about the size of a pear, with thick walls, capable under the influence of pregnancy of great expansion and growth. The broad part of the pear is called the body of the uterus; the lower narrow part is called the neck of the uterus, or cervix. The uterus in the adult girl or woman is about three inches long, two inches broad in its upper part and nearly an inch thick. It weighs from an ounce to an ounce and a half. When the uterus is in a pregnant condition, it increases enormously, both in size and in weight, as we will see in a future chapter. The cavity of the uterus is somewhat triangular in shape; at each upper angle is the small opening communicating with the Fallopian tube; the upper portion of the uterus is called the fundus; the external opening of the womb, situated in the center of the cervix, is called the mouth of the womb, or the os, or external os.
The uterus is situated in the center of the pelvis, between the bladder and the rectum. It is supported by certain ligaments, the chief of which are the broad ligaments; but, on account of general weakness, too hard physical labor, or lifting heavy weights, the ligaments may stretch, and the uterus may sink down low in the vagina, and we then have the condition known as prolapse of the womb. Or, the womb may turn forward, when we have a condition of anteversion. If the womb is bent (or flexed) forward on itself the condition is called anteflexion. If the womb is turned backwards, the condition is called retroversion; if it is bent or flexed backward upon itself the condition is called retroflexion. An extreme degree of anteversion or anteflexion, or retroversion or retroflexion, may interfere with impregnation, as the spermatozoa may find it difficult or impossible to reach the opening of the womb—the external os.
The entire cavity of the uterus is lined by a mucous membrane;[1] this mucous membrane is called the endometrium (endo—within; metra—uterus). An inflammation of the endometrium is called endometritis. It is the endometrium that is principally concerned in menstruation—that is, it is from it that the monthly discharge of blood comes.
The Vagina [vagina in Latin—a sheath]. The vagina is the tube or canal which serves as a passage-way between the uterus and the outside of the body. It extends from the external genitals or vulva to the neck of the womb, embracing the latter for some distance. It is a strong, fibromuscular canal, lined with mucous membrane. It is not smooth inside, but arranged in folds, or rugæ, so that when necessary, as during childbirth, it can stretch enormously and permit the passage of a child's head. The length of the vaginal canal is between three and five inches, but it is in general much more capacious in women that have borne one or more children than in those who have not borne any.
Near the vaginal entrance are situated two small glands; they are about the size of a pea, and secrete mucus. They are called Bartholin's glands; occasionally they become inflamed and give a good deal of trouble.

The Hymen [hymen in Greek—a membrane]. The external opening of the vagina, in virgins, that is, in girls or women who have not had sexual intercourse, is almost entirely closed by a membrane called the hymen. The vulgar name for hymen is "maidenhead." The hymen may be of various shapes, and of different consistency. In some girls it is a very thin membrane, which tears very readily; in others it is quite tough. On the upper margin or in the center of the hymen there is an opening which permits any secretion from the vagina and the blood from the uterus to come through. In rare cases there is no opening in the hymen, that is, the vagina is entirely closed. Such a hymen is called imperforate (not perforated). When the girl begins to menstruate, the blood cannot come out and it accumulates in the vagina. In such cases the hymen must be opened or slit by a doctor. In some cases the hymen is congenitally absent; that is, the girl is born without any hymen. While the hymen is usually ruptured during the first intercourse, it, in some cases, being elastic and stretchable, persists untorn after sexual intercourse. It will therefore be seen that just as the presence of the hymen is no absolute proof of virginity, so is the absence of the hymen no absolute proof that the girl has had sexual relations, She might have been born without any hymen, or it might have been ruptured by vaginal examination, by a vaginal douche, by scratching to relieve itching, or by some accident.
The remains of the hymen after it is ruptured shrink and form little elevations which can be easily felt; they are known as caruncles. [In Latin, carunculæ myrtiformes, which means in English myrtleberry-shaped caruncles; caruncle is a small fleshy elevation; derived from caro, which in Latin means flesh.]
The Vulva. The external genitals of the female are called the vulva. The vulva consists of the labia majora (meaning the larger lips), which are on the outside and which in the grown-up girl are covered with hair, and the labia minora (the smaller lips), which are on the inside and which are usually only seen when the labia majora are taken apart.
[Vulva in Latin means folding-door. The ancients Were fond of giving fancy names to things.]
The Mons Veneris. The elevation above the vulva, which during puberty becomes covered with hair, is called by the fanciful name, mons Veneris, or Venus' mountain. It is usually well padded with fatty tissue.
The Clitoris. The clitoris is a small body about an inch in length, situated beneath the mons Veneris and partly or entirely covered by the upper borders of the labia minora.
The Urethra. Between the clitoris above and the opening of the vagina below is situated the opening of the urethra, or the urinary meatus, through which the urine passes. Many women are so ignorant, or, let us say innocent, that they think the urine passes out through the vagina. This is not so. The vagina has nothing to do with the process of urination.
Again enumerating the female sex organs, but in the reverse order, from before backward, or from out inward, we have: The mons Veneris and the labia majora, or the external lips of the vulva; these are the plainly visible parts of the female genital organs. When the labia majora are taken apart we see the labia minora; when the labia majora and minora are taken apart we can see or feel the clitoris and the hymen, or the remains of the hymen. We then have the vagina, a large, stretchable musculo-membranous canal, in the upper portion of which the neck of the womb, or the cervix, can be seen (when a speculum is used), or felt by the finger. Only the cervix, or neck of the womb,
