The Creighton Model System is the first system of its kind to network family planning with reproductive health. It can be used by married couples to achieve, avoid, or space pregnancies, or by any woman to monitor her health, from puberty to menopause. In conjunction with the new women's health science of NaProTECHNOLOGY, it offers new hope to women suffering from reproductive health problems and couples struggling with infertility. 

​

The system is all natural, hormone-free, and eco-friendly. It is safe and effective; the effectiveness of the system to avoid pregnancy, when used according to the instructions of the system, is 99.5%, and the effectiveness to achieve pregnancy is 98% within the first six months. This enables infertility to be identified and treated a full six months sooner in couples using the system than in those who are not. The system is easy to learn and comparatively inexpensive when compared to other methods that are available.
