Reliable indicators to detect the fertile and infertile phases in the menstrual cycle are now available, largely due to the intensive scientific research into fertility over the past decade. This means that couples who follow the rules of the different NFP methodologies have a highly effective means of birth control, without the introduction of hormones, chemicals or devices into the body. New scientific techniques can be expected within the next couple of years which will simplify the detection of the fertile phase and hopefully help to elucidate the grey area of the early fertile days, where most of the unplanned pregnancies occur. Fertility awareness by both partners is an important positive contribution to the whole sexual relationship and emphasizes that NFP is an educational delivery system rather than a technological one. The modification of sexual behaviour and the motivation of both partners for the successful use of NFP may initially present a problem to some couples. On the other hand, many partners find the discipline enhances their sexual relationship and dialogue. Whatever the motivation, today more and more couples are happier to be in autonomous control of their bodies and their fertility.
现在已有可靠指标来检测月经周期中的易孕期和不易孕期,这主要归功于过去十年对生育能力的深入科学研究。这意味着遵循不同自然计划生育方法规则的夫妇有一种高效的避孕方式,无需将激素、化学物质或器械引入体内。预计未来几年会出现新的科学技术,这将简化易孕期的检测,有望帮助阐明早期易孕天数的灰色地带,而大多数意外怀孕都发生在这个时期。夫妻双方对生育能力的了解对整个性关系有着重要的积极贡献,并强调自然计划生育是一种教育体系而非技术体系。性行为的改变以及夫妻双方成功使用自然计划生育的动机,最初可能会给一些夫妇带来问题。另一方面,许多夫妻发现这种自律增强了他们的性关系和交流。无论动机如何,如今越来越多的夫妇更乐于自主掌控自己的身体和生育能力。
