It is possible that while the parasite prevents the development of testis or ovary in the host, it gives up to the body of the host a hormone from its own ovaries which tends to develop the female secondary characters: for the parasite is itself a Crustacean, and therefore the hormone from its ovaries would not be of too different a nature to act upon the tissues of the host.
These investigators removed the ovaries from an albino guinea-pig, and in their place substituted the ovaries of a black guinea-pig. "From numerous experiments it may be emphatically stated that normal albinos mated together produce only albinos." But in this experiment the result was otherwise, for the albino into which the ovaries of a black guinea-pig were grafted produced only black offspring.
The process of the growth of the ovaries is very gradual, and their function of ripening and discharging one ovum monthly into the Fallopian tubes and uterus, is not completed until between the twelfth and fifteenth years. WHAT SCIENCE KNOWS. After the sexual embrace we know that the sperm is lifted within the genital passages or portion of the vagina and mouth of the uterus.
Physically, he puts on fat almost immediately. When women have, for any reason, had their ovaries removed by surgical operation, marked changes follow, which vary much in detail, but carry certain general similarities. The face and body age rapidly in appearance, and there is a slowing up of functions of the organs, with a tendency to masculinity in tastes, behavior, feelings.
I therefore tried grafting ovaries from straight-eared females into lop-eared individuals. The operation was perfectly successful in seven specimens that is to say, they recovered completely and lived for many months, up to a year or more afterwards, but none of them became pregnant.
Examination showed this to be a case of active intrauterine hemorrhage excited by coitus soon after the menstrual flow had ceased and while the uterus and ovaries were highly congested. In another case the patient commenced flooding while at the dinner table in the Metropolitan Hotel in New York, and from the same cause an almost fatal hemorrhage ensued.
It spreads to the uterus, Fallopian tubes and ovaries and may even affect peritoneal tissues, first of the pelvis, then of the abdomen may even finally affect the heart and joints. Of course, these are rather the extreme limit, but they are not at all rare cases.
The ovulation theory was refuted by the following facts: Ovulation may and does occur without menstruation; women who have never menstruated may conceive; conception may occur during lactation, without the menses having returned since the last parturition; children at birth have many ovules contained within the ovaries; ovulation may persist for a time after the menopause, and even pregnancy has occurred, although very rarely after this time; the menses may continue regularly after the removal of the ovaries and Fallopian tubes; this is exceptional, and, as a rule, the periods only continue for two or three years at longest.
And the dangers incident to the development of new activity in the ganglionic nervous system by the functions of the ovaries, the dangers of irregular circulation, vaso-motor spasm and paralysis, are to be averted by systematic physical exercise, that shall stimulate the spinal nerves, quicken the external circulation, and favor the development of muscles at the moment that their activity threatens to be overpowered.
Sterility, in a female, most frequently depends upon a weakness or irritability either in the ovaries or the womb, and anything having a strengthening effect upon either organ will remove the disability. "OVER-INDULGENCE in intercourse," says Dr.
