IMPREGNATION.
1. CONCEPTION OR IMPREGNATION.—Conception or impregnation takes place by the union of the male sperm and female sperm. Whether this is accomplished in the ovaries, the oviducts or the uterus, is still a question of discussion and investigation by physiologists.
2. PASSING OFF THE OVUM.—"With many women," says Dr. Stockham in her Tokology, "the ovum passes off within twenty-four or forty-eight hours after menstruation begins. Some, by careful observation, are able to know with certainty when this takes place. It is often accompanied with malaise, nervousness, headache or actual uterine pain. A minute substance like the white of an egg, with a fleck of blood in it, can frequently be seen upon the clothing. Ladies who have noticed this phenomenon testify to its recurring very regularly upon the same day after menstruation. Some delicate women have observed it as late as the fourteenth day."
3. CALCULATIONS.—Conception is more liable to take place either immediately before or immediately after the period, and, on that account it is usual when calculating the date at which to expect labor, to count from the day of disappearance of the last period. The easiest way to make a calculation is to count back three months from the date of the last period and add seven days; thus we might say that the date was the 18th of July; counting back brings us to the 18th of April, and adding the seven days will bring us to the 25th day of April, the expected time.
4. EVIDENCE OF CONCEPTION.—Very many medical authorities, distinguished in this line, have stated their belief that women never pass more than two or three days at the most beyond the forty weeks conceded to pregnancy—that is two hundred and eighty days or ten lunar months, or nine calendar months and a week. About two hundred and eighty days will represent the average duration of pregnancy, counting from the last day of the last period. Now it must be borne in mind, that there are many disturbing elements which might cause the young married woman to miss a time. During the first month of pregnancy there is no sign by which the condition may be positively known. The missing of a period, especially in a person who has, been regular for some time, may lead one to suspect it; but there are many attendant causes in married life, the little annoyances of household duties, embarrassments, and the enforced gayety which naturally surrounds the bride, and these should all be taken into consideration in the discussion as to whether or not she is pregnant. But then, again, there are some rare cases who have menstruated throughout their pregnancy, and also cases where menstruation was never established and pregnancy occurred. Nevertheless, the non-appearance of the period, with other signs, may be taken as presumptive evidence.
5. "ARTIFICIAL IMPREGNATION".—It may not be generally known that union is not essential to impregnation; it is possible for conception to occur without congress. All that is necessary is that seminal animalcules enter the womb and unite there with the egg or ovum. It is not essential that the semen be introduced through the medium of the male organ, as it has been demonstrated repeatedly that by means of a syringe and freshly obtained and healthy semen, impregnation can be made to follow by its careful introduction. There are physicians in France who make a specialty of "Artificial Impregnation," as it is called, and produce children to otherwise childless couples, being successful in many instances in supplying them as they are desired.
