Natural Family Planning (NFP)


seanChildren too are a gift from the Lord, the fruit of the womb, a reward. Like arrows in the hand of a warrior are the children born in one's youth. Blessed are they whose quivers are full. They will never be shamed contending with foes at the gate.
Psalm 127: 3-5

Like a fruitful vine your wife within your home, Like olive plants your children around your table.
Psalm 128: 3-420wk unborn

What is Natural Family Planning?

Women make and record observations of cervical mucus, temperature, and cervical conformation. In the Creighton model, women make only external observations using toilet tissue when they normally use the bathroom. Because external observations have been studied and correlated with hormone analysis and ultrasound in past studies, women can rapidly develop confidence that the observations she is making are reflective of her fertility cycles.

By knowing and understanding the cycles of fertility, the couple can make decision together on how to use those days. The couple can mutually decide if they want to avoid or to achieve pregnancy on any given day. This gives both the man and the woman input and responsibility for their combined fertility.

Fertility patterns can change during life such as during breastfeeding, stress, and menopause. Women are also taught how to analyze their patterns during these changes thereby making NFP a credible family planning system throughout a woman's reproductive life.

NFP is not the rhythm method, "Roman Roulette," or "Catholic contraception." The rhythm method was based on the calendar and was the first attempt by scientists to understand the human female fertility cycle. Ogino of Japan and Knaus of Austria separately discovered in 1930 that ovulation is related to the following menstrual flow, not the previous flow. Unfortunately, much of the old statistics of the rhythm method are thrown in with NFP data by people who do not understand that there is a difference.

Values: Contraception vs. NFP

We must ask ourselves who we really believe is the author of marriage and of life? Us or God? Marital intercourse is the expression of the marital covenant - total, faithful, and free gift of self.
(C. West: Good News About Sex & Marriage)

In sexual intercourse we bare not only our bodies but our souls as well. Contraceptive sex even in marriage is not total, faithful, and free because the total person is not given. On the other hand, marital sex that is open to life (meaning open to God) is liberating and affirming. A couple using NFP waits for intercourse until they can give totally (i.e., during the infertile time of the cycle). In the fertile phase, a couple not seeking pregnancy continues to develop their sexual relationship - spiritually, intellectually, creatively, emotionally. If they focus on the physical, they they will miss out on so much of their spouse's personality.

We must be very careful how we use our sexuality because it is key in the transmission of life. When we trivialize sexuality and fertility, we are in grave danger of trivializing life. With NFP, we are responsible stewards of life. Remaining always open to new life doesn't mean always a pregnancy. It means we are always open to God's will. This is no different than conforming our will to God's will in the rest of our lives. Additionally, remaining open to life means we are also open to our spouses.

With contraception we become masters of life. We start believing that pregnancy is a failure. This is illogical because sexual intercourse is designed for babies and bonding. It means we are only sometimes open to life. It follows that we are not always open to God, the Author of Life. This mindset will affect all other aspects of our lives including our relationship with our spouse.

What the World Teaches:
What the Church Teaches:
Sexuality involves genitals only Sexuality involves the total person: spirit, body, intellect, emotion
The Goal is self-gratification The Goal is unity & generosity - whole & holy union that is open to life
Focus is on individual's own physical pleasure Focus is on total & reciprocal self-giving which includes physical pleasure
Self-denial will reduce the individual's pleasure Chastity & periodic abstinence will lead to self-mastery
Children are by-products of sex Children are gifts resulting from the holy trinity of husband+wife+God
Virginity is an abnormal state Virginity is a gift to be given to a spouse or to God - it is honored.
A person is disintegrated into parts with priority given to the physical The whole person remains intact
Fertility is the woman's problem Fertility is a shared responsibility
Fertility is a disease Fertility is appreciated
Children are valued only if wanted Children are cherished - planned or unplanned
Relationships should never impede an individual's progress toward self-fulfillment and are therefore impermanent Relationships continually grow in all aspects because of freedom to love & be loved as a total person
Love ends at the individual Love grows and multiplies endlessly
The Church does NOT teach that couples must have large families. Couples are to embrace responsible parenthood where in couples collaborate with God in the generation and education of new lives. There may be serious reasons to space children, temporarily or permanently. These may include physical, psychological, or external reasons. The number and spacing of children is left to the couple's conscience that is properly conformed to God's will. (Human Vitae, 1968)

Apparently most of the medical community does not accept that there is an association of breast cancer and the birth control pill. However, there are points to consider like the following three:
1) The analysis of the statistics by Christopher Kahlenborn, M.D. in Breast Cancer: Its link to Abortion and the Birth Control Pill, (One More Soul, 2002).
2) The prospective study on hormone replacement therapy published Spring, 2002 has shown a strong increase in breast cancer risk in those women who use hormone replacement for greater than 5 years. The risk increse was so apparent that the study was stopped early in order to inform the participants and the medical community.
3) Norcal Mutual Professional Liability Insurance stated in its June 2002 newsletter on breast cancer that the company is tracking history of oral contraceptives usa as a risk factor.

Creighton Model Fertility Care System

The Creighton Model Fertility Care System has been extensively evaluated over the past 22 years through research first at St. Louis University and Creighton University Schools of Medicine and most recently at the Pope Paul VI Institute for the Study of Human Reproduction (Omaha, Nebraska). It is a system that accurately monitors reproductive and gynecologic health and can be used to achieve or avoid pregnancy. The current trend toward managing human fertility in ways that are either suppressive or destructive (contraception, sterilization, abortion, in vitro fertilization, etc.) cannot be healthful for women and are contrary to the teachings of the Catholic Church.
This model is medically safe, it respects the dignity of women and the integrity of marriage, it cooperates with the procreative system and does not suppress it and it is effective. It allows for the first time the opportunity to network family planning with reproductive and gynecologic health maintenance. It is a system that is morally acceptable to all people. It is a system for every woman for her entire reproductive life. You can log on to their website at:


Couple to Couple League (CCL)

The CCL is an international, interfaith, nonprofit organization dedicated to teaching Natural Family Planning (NFP) to married and engaged couples. In addition the CCL produces audio-visual presentations and publications on several related subjects, such as pre-marital chastity, introductions to NFP for young people and marriage preparation groups, and materials encouraging full-time mothering.
