Natural Family Planning


God designed marriage as an "intimate partnership of life and love" (see Gaudium et spes, no.48).  In God's design, marriage is a unique union of one man with one woman "for the whole of life" (see Canon 1055, The Code of Canon Law).  Marriage is oriented to the good of the spouses and to the creation of nurture of new human life (see Gaudium et spes, no. 48).  Making decisions therefore, about when and how many children to have in marriage is a sacred responsibility that God has entrusted to husband and wife.  This is the foundation of what the Church calls, "Responsible Parenthood" --the call to discern God's will for your marriage while respecting His design for life and love.

The Catholic Church supports the methods of Natural Family Planning (NFP) because they respect God's design for married love.  In fact, NFP represents the only authentic approach to family planning available to husbands and wives because these methods can be used to both attempt or avoid pregnancy.  When learning about NFP, it is important to know that:

Natural Family Planning is an umbrella term for certain methods used to achieve and avoid pregnancies.  These methods are based on observation of the naturally occurring signs and symptoms of the fertile and infertile phases of a woman's menstrual cycle.  Couples using NFP to avoid pregnancy abstain from intercourse and genital contact during the fertile phase of the woman's cycle.  No drugs, devices, or surgical procedures are used to avoid pregnancy.

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)  Information taken from

**The Marquette Method is taught right here at Immaculate Conception Parish. The Marquette Model (MM) system brings 21st century technology to NFP. It is a system that uses an algorithm with other biological signs of fertility (i.e., urine hormones, mucus and/or temperature) to help identify the woman's fertile window. The Clearblue fertility monitor is an at home device that measures hormone levels in urine to estimate the beginning and end of the time of fertility in a women's menstrual cycle. The information from the monitor can be used in conjunction with observations of cervical mucus, basal body temperature, or other biological indicators of fertility. The MM was developed by professional nurses and physicians at Marquette University in the late 1990's. Learning how to monitor fertility through NFP aids a couple in the understanding, appreciation, and holistic integration of this precious gift. Please contact the listed instructor for more information. (Description by Marquette University Institute for Natural Family Planning). 

Classes consist of 1 initial session that is about 1.5 hours.  Class, text,charts, and follow up support are included for a one time $100 fee that supports NFP at Immaculate Conception Church.
