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.
