The Marquette Method was developed by Dr. Richard Fehring (PhD, RN) and his team of researchers at the Marquette Institute for Natural Family Planning, and is backed by evidence-based, peer-reviewed medical research.
Much of Dr. Fehring’s research is publicly available. Follow the links below to learn more about the research that supports each of the Marquette Method protocols.
