Natural Family Planning



“Helping couples live with their God-given gift of fertility”


Reflecting the mission of Marquette University, the mission of the INFP is to serve God by contributing to the advancement of knowledge in NFP and by collaboration with the Catholic Church in local, state and national NFP programs.

Definition of natural family planning

Natural family planning is a general term that applies to various methods that have been developed to help women and men determine the fertile and infertile times of a woman's menstrual (monthly) cycle. These methods can be used to achieve or avoid pregnancy. All of the methods rely on the interpretation of natural biological signs or indicators of fertility. Implicit in these methods are that couples abstain from intercourse and genital contact during the fertile time of the woman's cycle if they are avoiding pregnancy. Use of any artificial means to interfere with fertility is not natural family planning.

There are four basic methods of natural family planning:

Our method of NFP applies these devices in helping the new learner of NFP to gain confidence in the self-interpretation of the woman's natural signs of fertility. All methods of NFP in some way help a man and a woman get a better picture of their fertility. Learning about one's fertility aids in understanding, appreciating and holistically living with this precious gift.
