Natural Family Planning (NFP) is a term for fertility awareness-based methods of family planning that are science-based, accurate, natural, healthy, and effective. NFP is supported by the Catholic Church because it respects God's design for married love. NFP is based on scientific facts about fertility and women's menstrual cycles, and it can be used to both achieve and avoid pregnancy. The effectiveness of NFP depends on the couple's commitment to cooperation and communication, as well as their ability to correctly interpret the signs of fertility. While NFP can be effective for some, it may not work for everyone, especially if there are inconsistencies in the woman's menstrual cycle.

Natural Family Planning (NFP) is a scientific, natural, and moral method of family planning
NFP is unique among methods of family planning as it enables users to work with their bodies rather than against them. It does not involve any artificial methods, drugs, devices, or surgical procedures. Instead, it calls for shared responsibility and cooperation between the husband and wife, inspiring spousal communication and encouraging a couple to understand their bodies and their combined fertility.
The Catholic Church supports NFP as it is in line with Catholic teaching, which considers contraception a serious sin. NFP reflects the dignity of the human person within the context of marriage and family life, promoting openness to life and recognizing the value of the child. It can be used by doctors to evaluate a woman's health and has none of the harmful side effects caused by contraception.
NFP is effective for both achieving and avoiding pregnancy. To avoid pregnancy, couples abstain from intercourse and genital contact during the fertile phase of the woman's cycle. To achieve pregnancy, intercourse takes place during the fertile phase. NFP can be used throughout a woman's reproductive life and has helped many couples struggling with infertility to conceive.
Overall, NFP is a scientific, natural, and moral method of family planning that respects the body and soul of individuals while promoting responsible parenthood within the context of marriage.

NFP is based on scientific facts about fertility and the menstrual cycle
Natural Family Planning (NFP) is based on scientific facts about fertility and the menstrual cycle. NFP is an umbrella term for certain methods used to achieve and/or 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.
The methods of NFP are based on scientific research about the signs of fertility and the menstrual cycle. Over a century ago, scientists discovered cyclic changes in cervical mucus and their relation to ovulation. In the 1920s, scientists identified the temperature rise that signals ovulation. It was not until the 1950s that scientists developed programs to teach others how to observe and interpret these fertility signs. Today, ongoing research continues to refine the methods of NFP.
NFP methods are based on the understanding that a woman's body provides several ways to identify the fertile and infertile times of her menstrual cycle. The rise and fall of reproductive hormones are responsible for these signs. Recognizing the pattern of those physical signs forms the basis for all methods of NFP.
Around the time of ovulation, a fluid or "mucus" is released from the woman's cervix (the opening of the uterus). When cervical mucus is present, it has the ability to keep sperm alive in the woman's body for several days. Another sign of fertility that can be observed is a woman's daily waking temperature or "basal body temperature" (BBT). The BBT is taken after several hours of uninterrupted sleep. A woman's BBT is lower prior to ovulation and will rise by 0.4 to 0.6 degrees Fahrenheit, staying elevated after ovulation.
NFP is unique among methods of family planning because it enables its users to work with the body rather than against it. NFP methods promote a holistic approach to family planning, which both respects procreation and has the potential to deepen the intimacy of husband and wife.

NFP can be used to both achieve and avoid pregnancy
Natural Family Planning (NFP) is an umbrella term for certain methods used to achieve and avoid pregnancies. NFP is approved by the Catholic Church and some Protestant denominations. It is based on the observation of the naturally occurring signs and symptoms of the fertile and infertile phases of a woman's menstrual cycle.
NFP methods are not contraception, and their effectiveness works both ways—for achieving and postponing pregnancy. When couples wish to attempt pregnancy, they can time sexual intercourse to the fertile window of the menstrual cycle, thereby optimizing the possibility of becoming pregnant. When couples wish to postpone pregnancy, they can abstain from intercourse and genital contact during the fertile phase of the woman's cycle.
The effectiveness of NFP depends upon spouses’ following the rules of the method according to their family planning intention. When couples understand the methods and are motivated to follow them, NFP is up to 99% successful in spacing or limiting births. Studies show that couples who follow their NFP method’s guidelines correctly and all the time achieve effectiveness rates of 97-99%.
NFP is completely organic, adding no artificial hormones or devices to the body, and has no harmful side effects. NFP is also economical, as typically, a couple only pays for the class, and the rest of the planning is cost-free.
