Effectiveness of NFP

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.

Multiple studies have shown Natural Family Planning to be as effective as the hormonal birth control pill in avoiding pregnancy, and even more effective than other common methods of contraception. See below!
