In a paper on the preservation of the hymen, Dr. Hannah M. Thompson writes: "Further, if the hymen was intended as a guarantee of moral character, and for moral protection, either of man or woman, would we not have some reason for reflecting on the wisdom and righteousness of a Creator who has failed to make equal provision, and to give a like guarantee of an uncorrupted manhood? As physicians, we know too well that where one woman enters the marriage relation tainted in body there are thousands of men reeking with disease; and there is no demonstrable test to distinguish these, no proof for the young woman of the virginity or virtue of the young man." The Bladder.-- The female bladder is relatively broad and capacious, and is also highly distensible. When the bladder is allowed to become overdistended, it is carried backward and tends to cause a backward displacement of the uterus. The urethra, or excretory duct of the bladder, is about an inch and a half long, and lies firmly imbedded in the anterior vaginal wall. The Vagina.-- The intermediate organ is the vagina. This is a musculo-membranous canal which connects the external with the internal organs of generation. The vagina lies in relation with the bladder and the urethra in front, and with the rectum behind. The vagina is sufficiently distensible to allow of the passage of so large a body as the child. The Uterus.-- The internal organs of generation are the uterus, the ovaries, and the Fallopian tubes. Of these, the ovaries and the uterus are the essential female organs of generation. The virgin uterus is a small, hollow, muscular organ, somewhat pear-shaped, whose cavity is about one and a half inches deep. The uterus is divided by a natural constriction into a body and a neck. The neck, or cervix, is somewhat spindle-shaped, and has a canal running through its center which opens by a small aperture-- the so-called external orifice,-- into the vagina. In the virgin uterus the apposition of the anterior and posterior walls reduces the cavity to little more than a longitudinal cleft. With the advent of old age the whole organ suffers marked atrophy. The uterus is situated in the middle of the pelvic cavity, between the bladder and the lower bowel. It is held in place by broad elastic bands which go to different sides of the pelvis; it is also in part supported by the structures below and above it. But so loosely is the uterus held that it is easily pushed about-- as, for instance, by a full bladder or a packed bowel. And persistently allowing the bladder to become overfull, and failure to have a daily evacuation of the bowels, are prolific sources of displacements of the womb.
