Such continence as is involved in dependence upon the so-called "safe period" for family limitation will harm no one. The difficulty here is that the method is not practical. It simply does not work. The woman who employs this method finds herself in the same predicament as the one who believes that she is not in danger of pregnancy when she does not respond passionately to her husband. That this woman is more likely to conceive than the emotional one, is a well-known fact. The woman who refuses to use contraceptives, but who rejects sex expression except for a few days in the month, is likely to learn too soon the fallacy of her theory as a birth-control method. For a long time the "safe period" was suggested by physicians. It was also the one method of birth control countenanced by the ecclesiastics. Women are learning from experience and specialists are discovering by investigation that the "safe period" is anything but safe for all women. Some women are never free from the possibility of conception from puberty to the menopause. Others seemingly have "safe periods" for a time, only to become pregnant when they have begun to feel secure in their theory. Here again, continence must give way, as a method of birth control, to contraceptives. In the same category as the "safe period," as a method of birth control, must be placed so-called "male continence." The same practice is also variously known as "Karezza," "Sedular Absorption" and "Zugassent's Discovery." Those who regard it as a method of family limitation are likely to find themselves disappointed. As a form of continence, however, if it can be called continence, it is asserted to bring none of the long course of evils which too often follow the practice of lifelong abstinence, or abstinence broken only when a child is desired. Its devotees testify that they avoid ill effects and achieve the highest possible results. These results are due, probably, to two factors. First, those who practice Karezza are usually of a high mental and spiritual development and are, therefore, capable of an exalted degree of self-control without actual repression. Second, they have the benefit of that magnetic interchange between man and woman which makes for physical, mental and spiritual wellbeing. This stimulation becomes destructive irritation in ordinary forms of continence.
