The question whether sexual intercourse is permissible during pregnancy is often put to the physician. Some extremists and theorists demand complete abstinence during the entire duration of pregnancy. Such abstinence is not only not feasible, but is unnecessary and may prove a disrupting factor; it may create not only dissension, it may wreck the love-life of husband and wife. I know of cases where the wife, influenced by the wrong teachings about the necessity of complete abstinence during pregnancy, about the possible injury to the child from intercourse, persisted in keeping the husband away; and the result was that the husband began to go to other women, and he got in the habit to such an extent that he refused to give up entirely, even after the child was born. It cannot be expected from a married man, who is used to more or less regular sexual relations, to abstain entirely for nine or ten months. Such a demand is unreasonable and uncalled for. All claims about the injurious effects of intercourse on the mother and child lack proof and foundation. During the first four months of pregnancy no change need be made in the usual sex relations. Their "intensity" should be moderated, their frequency need not. During the fifth, sixth and seventh months intercourse should be indulged in at rarer intervals—once in two or three weeks—the act should be performed without any violence or intensity, and the usual position should be reversed or changed to a lateral one. During the eighth and ninth months relations had best be given up altogether.
And this abstinence should last until about six weeks after the birth of the child. During this period the uterus undergoes what we call involution; that is, it goes back to the size and shape it had before pregnancy, and it is best not to disturb this process by sexual excitement, which causes engorgement and congestion.

SEXUAL INTERCOURSE FOR PROPAGATION ONLY
Belief in Sexual Intercourse for Propagation Only—What Such Practice Would Lead to—Nature and the Sex-fanatics—Sexual Desire in Woman After Menopause—Sex Instinct of Sterile Men and Women—Sex Instinct Has Other High Purposes.
Some people sincerely believe that the sexual instinct is for reproductive purposes only; they claim we should never indulge in sexual intercourse unless it be for the purpose of bringing a child into the world. The act performed without such aim in view is stigmatized by them as carnal lust, as a sin. Some even say that such an act is equivalent to an act of prostitution. To argue the question with such people would be a waste of time. It is not fair to impugn the good faith, the sincerity of your opponents, because I have convinced myself that the most insane, most bizarre notions may be held by otherwise sane people in perfect sincerity. But we cannot help questioning the reasoning faculties of people holding such beliefs.
Let us see where the belief of "sex relations for procreation only" would lead us to. In a normal healthy couple impregnation follows one connection. So if a couple wanted to limit themselves to three or four or six children, they would be entitled to have relations only three, four or six times in their lives. For it must be remembered that during pregnancy sexual relations would be prohibited, as during pregnancy no further impregnation can take place, and no intercourse must take place which has not for its purpose the conception of a new human being. If the people were believers in big families, and agreed to have twelve children—no anti-Malthusian would expect more than that—they would be entitled to twelve relations during their marital life. Assuming that not every act is followed by pregnancy, but that it takes on the average three or four times to bring about the desired result, we will have it that during the wife's childbearing period the couple may indulge in sex relations from once in three or four years to once or twice a year.
