When properly taught and practised, natural family planning can be a highly effective form of birth regulation. Recent studies indicate low failure rates of less than three pregnancies per 100 women years for couples with a strong motivation to follow the method. Studies show that pregnancy rates are high when the rules for avoiding pregnancy are not adhered to. Successful natural family planning can lead to heightened self esteem and marital enrichment.
如果教导有方且实践得当,自然计划生育可以成为一种非常有效的生育调节方式。近期研究表明,对于有强烈意愿遵循该方法的夫妇,其失败率较低,每100名妇女年的妊娠率不到3次。研究显示,不遵守避免怀孕的规则时,妊娠率会很高。成功的自然计划生育可以提升自尊并增进婚姻关系。
