What is Fertility Awareness and Natural Family Planning?
Natural Family Planning (NFP) and Fertility Awareness Based Methods allow a woman to track the fertile and infertile times during her reproductive cycle. She can use this information to better understand her health. NFP relies on specific methods in which a couple learns to observe the woman’s naturally occurring signs of fertile and infertile phases during a menstrual cycle. Couples can use this knowledge as a tool in their family planning and to better understand their combined fertility. Using fertility awareness and NFP is ultimately to accept the divine gift of spousal unity in marriage.
The United States Conference of Catholic Bishops (USCCB) has issued diocesan standards. They state:
NFP reflects the dignity of the human person within the context of marriage and family life and promotes openness to life and the gift of the child. By complementing the love-giving and life-giving nature of marriage, NFP can enrich the bond between husband and wife.
The St. Philip Institute is dedicated to providing the support that newly and not-so-newly married couples need to be aware of their fertility and plan their families in discernment with God’s will. Bishop Strickland declared in the Constitution on Teaching (21) that marriage formation in the Diocese of Tyler would include training in a method of NFP.
What Materials Do We Use?
The St. Philip Institute is cultivating various methods and courses for all levels of instruction in NFP methods, and we make those available for couples to enroll in and complete on your own. Additionally, our Family Life Office produces information from experts and testimonies from couples to help you learn how to live your marriage this way. We are building a network of NFP professionals trained in various methods thoughout the Diocese of Tyler so everyone will have access to these methods. Below you will find the information and our resources compiled.
If you are interested in being trained as a certified NFP instructor or teaching couple working directly with other couples to learn NFP methods, please contact Deanna Johnston in the Family Life Office. Pastors, catechists, and others who have questions about family life formation should also contact the Director of Family Life, Deanna Johnston.
Let’s be honest: when it comes to sharing Natural Family Planning with engaged and married couples, we are in competition with contraceptive culture. Sometimes, in our zeal for wanting couples to experience the fullness of what the Church teaches, we use language that only emphasizes the ease and effectiveness of a particular method and how great NFP can be for postponing pregnancy. However, when the conversation about NFP stops at merely postponing pregnancy, we aren’t giving couples the whole picture: that the beauty and fullness of the Church’s teaching on married love is a cross we embrace by placing our fertility in God’s hands.

This method requires the individual to track the characteristics and sensations of cervical fluid. By observing changes in cervical mucus each day throughout the menstrual cycle, a woman is able to note the fertile and infertile times in a cycle. Additionally, she is able to monitor overall gynecological health. In addition to helping couples achieve or avoid pregnancy, these methods can help evaluate infertility, repetitive miscarriage, recurrent ovarian cysts, pelvic pain, premenstrual syndrome, polycystic ovarian syndrome, and more.
