There are couples with unmet family planning needs and couples who do not use any modern method, yet they desire to space or avoid pregnancies. Many of them look for safe and effective options like the natural family planning methods. The Billings Ovulation Method based on single index cervical mucus parameter is one such option. The present multicentre trial conducted in India has shown an encouraging use-effectiveness of the method, indicating method failure as low as 1.5 +/- 0.3 and use-failure 15.9 +/- 0.8 per 100 users at 21 months. The method continuation rates have also been as high as 88.3/100 users at 6 months and 52.0/100 users at 21 months.
有一些夫妇存在未满足的计划生育需求，还有一些夫妇不使用任何现代避孕方法，但他们希望生育间隔或避免怀孕。他们中的许多人在寻找安全有效的方法，比如自然计划生育方法。基于单一宫颈黏液指标的比林斯排卵法就是这样一种选择。在印度进行的这项多中心试验表明该方法的使用效果令人鼓舞，在21个月时，每100名使用者的方法失败率低至1.5±0.3，使用失败率为15.9±0.8。该方法的持续使用率在6个月时高达每100名使用者88.3，在21个月时为每100名使用者52.0。
