“Me of my lawful pleasure she restrained And prey’d me oft forbearance; did it with A pudency so rosy the sweet view on’t Might well have warmed Old Saturn.” Especially justified is such refusal when coitus has been already once or twice performed, or when the consumption of alcoholic beverages has made the husband unduly lustful. On the other hand, the refusal of intercourse when demanded by the husband should never depend upon baseless feminine caprice, or upon the now so frequently asserted “rights of women.” Experience has long ago established as a fact that unduly frequent satisfaction of the sexual impulse entails serious consequences to the health of the individual. And in the case of the wife these consequences may be especially disastrous when intercourse is indulged in recklessly during menstruation, during all stages of pregnancy, and even during the puerperium. “Incontinence during menstruation leads to serious circulatory disturbances and to the consequences of these disturbances; during pregnancy it is likely to give rise to miscarriage; during the puerperium, to congestions and inflammations. Should conception occur as a result of intercourse during the lying-in period (and this may happen very shortly after childbirth), abortion, and even more serious consequences, are likely to ensue. By intercourse during lactation, the premature recurrence of the menstrual flow is induced, and the gradual reversion of the reproductive apparatus to the condition in which it was before pregnancy (the process of involution) is hindered; moreover, the secretion of milk is diminished or even entirely suppressed.” In these terms _Hegar_ depicts the consequences of premature resumption of marital intercourse, taking perhaps a somewhat extreme view of the matter. Nevertheless, this author is undoubtedly right in declaring that one of the principal disadvantages to a woman of excessively frequent sexual intercourse is that pregnancy occurs too often. It is astonishing to observe the number of full-term deliveries and miscarriages that a woman will experience within a comparatively short period of time, as is seen too frequently among the labouring classes and more especially among factory workers. “If we assume the ordinary mortality of childbed to be 6 per mille, a woman who in the course of 15 years undergoes labour (at full term or prematurely) 16 times, runs a risk of death to be expressed by the ratio of 6 × 16 = 96 per mille; that is to say, on the average, of 1,000 women who become pregnant as often as this, nearly 1 in 10 will die in childbed.”
