The Diocese of Des Moines

Natural Family Planning


Within marriage there is a moral responsibility to practice responsible parenthood, although not all practices used to regulate procreation are morally equivalent. Only Natural Family Planning respects the full integrity of the sexual act. Beyond moral considerations, NFP is 100% natural, it has been clinically proven to be 98-99% effective with proper use, and there are no harmful side effects.


 Because of the dishonest and immoral nature of artificial contraception, which has been confirmed in the constant teaching of Christ and His Church, only natural means of regulating births are morally licit.  The following resources can help couples learn about Natural Family Planning, which is great aid in participating in God’s plan for sexual intimacy.


In the Diocese of Des Moines, in order to ensure that our married couples have the opportunity to remain faithful to Christ’s teaching, we offer Natural Family Planning classes to engaged couples prior to their wedding. Approved methods are listed below, and if a couple would like to request the approval of an additional method they can do so by contacting Adam Storey at 515-237-5056 or After completing an NFP course, please fill out this survey in order to help us assess ways to improve marriage preparation.


Scholarships are available for all students based on need if completing a course is too expensive. To request a scholarship contact Adam Storey at 515-237-5056 or

Creighton Model FertilityCare System:


Creighton Model FertilityCare System ( - an authentic language of a woman's health and fertility! The CrMS relies upon the standardized observation and charting of biological markers that are essential to a woman's health and fertility. These "biomarkers" tell the couple when they are naturally fertile and infertile. These biomarkers also show when abnormalities exist and can be used to diagnose and treat many gynecologic conditions.


The course consists of an introductory presentation, followed by follow-ups with a practitioner. Follow-ups may be conducted via phone if distance is an issue.


Both practitioners listed below teach at Vitae Family Care Clinic in West Des Moines, and visits are covered by most health insurance plans.

Marquette Model system:


The Marquette Model (MM) system of NFP brings 21st century technology to NFP by using the ClearBlue Easy Fertility Monitor, a device used at home which 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 1990s. A recent (2007) study published in the Journal of Obstetric, Gynecologic, and Neonatal Nursing demonstrated a 97-98% efficacy of the MM in avoiding pregnancy when taught by a qualified teacher and correctly applied. This method can be learned online at 


There is an introductory session and a one month follow up session.  This class can be taught as a group session or individual.
