IS IT INJURIOUS TO HEALTH? It is sometimes urged against Birth Control that the use of contraceptive methods is injurious to the health of women, in some cases a long list of physical and mental ills being given as possible of being caused by such methods. Opposed to this is the contention of the members of the medical profession who have arrayed themselves on the side of scientific Birth Control. The latter authorities positively contradict the assertion that women's health is injured by the practice of rational and scientific methods of Birth Control; although these authorities freely admit, in fact they CLAIM, that certain unscientific methods and practices popular among certain persons--such as the use of certain chemicals and mechanical appliances--undoubtedly have resulted in physical harm, and they strongly advise against the use of such bunglesome methods. One of the leading medical advocates of scientific Birth Control in the United States throws down the gauntlet squarely before those of his profession, and others, who urge this objection to scientific Birth Control, in the following challenging words: "I challenge any physician, any gynecologist, to bring forth A SINGLE AUTHENTICATED CASE in which disease or injury resulted from the use of modern methods of prevention. I know they cannot do it." And others in the ranks of the medical profession have made similar assertions and claims. The unprejudiced person who will consult the best medical authorities on the subject will unquestionably agree that the best medical opinion of the day holds that scientific Birth Control is not in fairness to be open to this objection. IS BIRTH CONTROL UNNATURAL? Another favorite argument of the opponents of scientific Birth Control is the broad statement and claim that "all voluntary attempts to limit procreation are unnatural," and therefore wrong. This objection, while usually offered without any particular argument, explanation, or proof, must be carefully and honestly met and answered by the fair-minded advocate of Birth Control. In the first place, it may as well be admitted that regulation, restriction, or control of the procreative functions by application of the intellect or reasoning processes IS unnatural, in the sense of not being indicated by Nature and enforced through the instinctive actions of the race. The only instinct which primitive man seems to have had in this case (and these he held in common with the lower animals) was that of free and unlimited sexual intercourse, in response to his instinctive desires, with this exception (and this exception should be carefully noted), i. e.: that the male respected the instinctive disinclination to cohabit during the period in which the woman was pregnant, and often also during the period in which she nursed her infant. This instinct, unhappily for the race, the "civilized" man has overridden until it has practically ceased to manifest its voice.
