One of the questions you will likely be asked during marriage preparation is “How many children do you want?” While this may seem premature, it is important to begin discussing the desires you have for your future family. If one of you desires a large family, and the other is not open to the gift of children, you have a lot to talk about!

It is also helpful to talk about your plans for fulfilling those desires well before the honeymoon. This may go against what you believe, or what you have been taught by family, friends, in school, by your doctors or nurses, and from the culture, but it is the truth – contraception is not a safe and responsible way to plan your family, it thwarts God’s plan for life and love in marriage, and its use is an intrinsic evil. But do you know why?

The marital embrace was created by God to draw you together as one in intimacy and love in a unique and satisfying way while fulfilling God’s commandment to “be fertile and multiply”. It is simultaneously self-giving and life-giving, and God’s plan is that these elements not be separated. This is to help ensure that the act of marital love actually draws you closer together. When either element is absent, the act can easily be abused, with the most obvious example of engaging in it for purely selfish physical pleasure.

Recall from the previous section how we are called to love one another – freely, totally, faithfully and fruitfully. We are also called to this kind of love in each act of “making love”. If contraception is used, the marital embrace is neither free, total, faithful or fruitful.

Many couples wrongly assume that this teaching means that Catholic couples are called to have as many children as possible. While this may be what some couples discern is their call, many others, at least for some period in their marriage, may have a serious reason for delaying a pregnancy.

And the good news is that there is a natural, healthy, drug free, and scientific way that is highly effective in both delaying the conception of a child, and also in helping you to conceive a child. The method is Natural Family Planning (NFP).

In short, using the observable biological signs that God placed in a woman’s body, couples together track her fertility, and exercise the freedom to abstain from the marital embrace when they have together discerned through prayer that they are not ready for another child, and engage in intercourse during times of natural infertility, which is the majority of a woman’s cycle.

The scope of this guide does not provide the space necessary to discuss the fullness and beauty of the Church’s teachings on NFP, but please consider these important points.

• NFP is the only method of family planning in line with Church teachings – it’s God’s Divine Plan!
• NFP empowers husband and wife to know and understand each other’s body and the gift of fertility.
• NFP helps foster respect, trust, communication and cooperation between husband and wife.
• NFP helps to train a man to love a woman as Christ loves the Church, strengthening a couple’s spiritual bond with God and with each other.
• NFP enhances couple communication and intimacy, building healthy and loving marriages with less than a 4% divorce rate.
• NFP nurtures a deeper understanding and acceptance of children as blessings to be welcomed, treasured and loved beyond measure, building healthy and loving families.
• Periodic abstinence, while not always easy, provides periods of time to focus on other ways to love and care for each other.
• NFP is up to 99% effective when used to avoid or delay the conception of a child and has been highly successful in helping couples conceive when issues of infertility arise.
• Unlike oral contraceptives, there are no unwanted or harmful side effects.
• NFP is as green and natural as you can get, with no synthetic drugs or chemicals, no devices, and no surgical procedures, yet scientifically researched and tested.
• NFP is inexpensive, with minimal and sometimes no ongoing costs after initial instruction and supplies.
• Charting of fertility signs provides a valuable health record and diagnostic tool.

Individuals, couples, doctors, and nurses located throughout the diocese are professionally trained and devoted to helping you learn Natural Family Planning. Your priest and the person performing your marriage preparation are also available to answer any questions or concerns you may have and to provide you with resources and encouragement.

NFP Methods, Instructors & Physicians

1. Ovulation Method (Creighton Model)

Creighton Model FertilityCare practitioners provide NFP instruction in a series of private, personalized sessions with long-term professional follow-up care available. This method follows an allied health care model (NaProtechnology) and has a high success rate in achieving and avoiding pregnancy, as well as treating infertility and gynecologic problems.

2. Sympto-Thermal Method (Couple to Couple League)

The Sympto-Thermal Method (STM) is based on three key signs of fertility: cervical mucus, basal body temperature, and changes in the cervix. By observing and recording these signs, couples can identify fertile and infertile phases of the cycle.

To find out more about the Sympto-Thermal method of NFP, watch Learn NFP – An introduction to Natural Family Planning.

3. Marquette Model of NFP

The Marquette Model brings modern technology to NFP by using an algorithm with biological fertility signs to help identify the fertile window. It was developed by professional nurses and physicians at Marquette University.

4. Fertility Education and Medical Management (FEMM)

FEMM is a comprehensive women’s health and wellness program focused on optimal reproductive health through science-based fertility education.
