Natural Family Planning (NFP) is an umbrella term for certain methods used to achieve and avoid conception. These methods are based on the observation of the naturally occurring signs and symptoms of the fertile and infertile phases of a woman's menstrual cycle.
Some natural methods include use of fertility monitors to better understand the time of the wife's fertility. Married couples using NFP to postpone conception abstain from intercourse and genital contact during the fertile phase of the wife's cycle. No drugs, devices, or surgical procedures are used to avoid pregnancy. Married couples who use NFP to attempt a pregnancy, make use of the fertile window—the optimum time when
conception is likely.
NFP reflects the dignity of the human person within the context of marriage and family life, promotes openness to life, and recognizes the value of the child. By respecting the love-giving and life-giving natures of marriage, NFP can enrich the bond between husband and wife. (Standards for Diocesan Natural Family Planning Ministry, p. 23)
