Observations made at the Family Planning Clinic and a review of the literature show that there is no increased tendency towards the natural contraceptive method among advice-seeking couples. On the contrary-apart from a few exceptions-the most effective method is always chosen. The natural method presupposes a high degree of motivation, of readiness to communicate and of clarification. These prerequisites underly the relatively high rate of failure because not all couples have the right degree of understanding. Nevertheless, to many people this method is the only acceptable and morally justifiable one. Thus, precise and detailed instructions and frequent check-ups would be necessary especially during the first few months, until adequate experience is gained.
在计划生育诊所的观察以及对文献的回顾表明，寻求建议的夫妇中没有增加采用自然避孕方法的趋势。相反，除了少数例外，总是会选择最有效的方法。自然避孕法需要高度的积极性、沟通意愿和明确认知。这些先决条件导致了相对较高的失败率，因为并非所有夫妇都有正确的理解程度。然而，对许多人来说，这种方法是唯一可接受且在道德上合理的方法。因此，特别是在最初几个月，直到获得足够经验之前，需要提供精确而详细的指导以及频繁的检查。
