NATURAL FAMILY PLANNING
The controlling of human conception by restricting the marital act to the infertile periods of the wife. This practice is based on the theory that the period of a woman's ovulation can be determined with considerable accuracy. A variety of methods, or their combination, is used to determine the period of ovulation. From the moral standpoint, natural family planning is permissible. As stated by Pope Paul VI: "If there are serious motives to space out births, which derive from physical or psychological conditions of husband or wife, or from external conditions, it is licit to take account of the natural rhythms inherent in the generative functions" (Humanae Vitae, II, 16).
