THE FEMALE SEXUAL ORGANS.
1. The generative or reproductive organs of the human female are usually divided into the internal and external. Those regarded as internal are concealed from view and protected within the body. Those that can be readily perceived are termed external. The entrance of the vagina may be stated as the line of demarcation of the two divisions.
2. HYMEN OR VAGINAL VALVE.—This is a thin membrane of half moon shape stretched across the opening of the vagina. It usually contains before marriage one or more small openings for the passage of the menses. This membrane has been known to cause much distress in many females at the first menstrual flow. The trouble resulting from the openings in the hymen not being large enough to let the flow through and consequently blocking up the vaginal canal, and filling the entire internal sexual organs with blood; causing paroxysms and hysterics and other alarming symptoms. In such cases the hymen must be ruptured that a proper discharge may take place at once.
3. UNYIELDING HYMEN.—The hymen is usually ruptured by the first sexual intercourse, but sometimes it is so unyielding as to require the aid of a knife before coition can take place.
4. THE PRESENCE OF THE HYMEN was formerly considered a test of virginity, but this theory is no longer held by competent authorities, as disease or accidents or other circumstances may cause its rupture.
5. THE OVARIES.—The ovaries are little glands for the purpose of forming the female ova or egg. They are not fully developed until the period of puberty, and usually are about the size of a large chestnut. The are located in the broad ligaments between the uterus and the Fallopian tubes. During pregnancy the ovaries change position; they are brought farther into the abdominal cavity as the uterus expands.
6. OFFICE OF THE OVARY.—The ovary is to the female what the testicle is to the male. It is the germ vitalizing organ and the most essential part of the generative apparatus. The ovary is not only an organ for the formation of the ova, but is also designed for their separation when they reach maturity.
7. FALLOPION TUBES.—These are the ducts that lead from the ovaries to the uterus. They are entirely detached from the glands or ovaries, and are developed on both sides of the body.
8. OFFICE OF THE FALLOPIAN TUBES.—The Fallopian tubes have a double office: receiving the ova from the ovaries and conducting it into the uterus, as well as receiving the spermatic fluid of the male and conveying it from the uterus in the direction of the ovaries, the tubes being the seat of impregnation.
9. STERILITY IN FEMALES.—Sterility in the female is sometimes caused by a morbid adhesion of the tube to a portion of the ovary. By what power the mouth of the tube is directed toward a particular portion of an ovary, from which the ovum is about to be discharged, remains entirely unknown, as does also the precise nature of the cause which effects this movement.
