Scientifically Based

NFP methods are scientific, and are backed up by research and medical viability. NFP uses the science of the body to understand and evaluate its natural biomarkers of fertility. Many nurses and doctors are certified in methods of NFP and use them to work with their patients on fertility awareness, reproductive health, and general women’s health. Certain methods can even help to diagnose cancer and other diseases. Methods of NFP work cooperatively with the procreative and gynecologic systems instead of suppressing or manipulating them. Using NFP, medical professionals, especially those trained in NaPro Technology, can also identify and treat underlying cycle conditions and signs of infertility.

NFP is very effective in helping couples identify the optimum time for conception. With regard to spacing or limiting pregnancies, NFP is up to 99% successful when couples understand the methods, are motivated, and follow their method’s guidelines.
