conception may take place during or within a very short time after an act which is accompanied by a proper orgasm. Many women claim to experience peculiar unmistakable sensations as soon as conception has taken place, and by calculating the day of probable delivery we know that they are right. Taking therefore all the various data into consideration we are fully justified in saying that while an orgasm or a voluptuous sensation during the act is not at all _necessary_ to impregnation, it is in many cases a helpful factor. It is claimed by some that the offspring resulting from an orgastic act is apt to be healthier and better developed than offspring resulting from sexual intercourse in which the parties experience no orgasm. The reason given being that conception in the first instance taking place quickly, the spermatozoa are better nourished and more vigorous. In my opinion this is merely a fanciful hypothesis which needn't be taken seriously. It will be found rather frequently that women of strong passionate natures, with strong orgastic feelings, and normal in every way, fail to become mothers. A careful investigation of their menstrual discharge will show that _it is not because they failed to conceive_, but because the impregnated ovum is expelled each time; in other words, they have each month a miniature miscarriage. And these miscarriages, or rather abortions, are due to the spasmodic contractions of the uterus and its adnexae which accompany the orgasm. In such cases I have advised the woman to try to remain passive during the act, to repress the orgasm, and the results have in some instances shown the wisdom of my advice. After conception has taken place, after one period has been missed, the woman should abstain from intercourse altogether or at least for two or three months until the fetus is securely attached to, or ensconced in, the uterus.
