Natural Family Planning


The Carondelet Fertility Care Center at St. Joseph’s Hospital in Tucson encourages couples to share the responsibility of planning their families. Using the Creighton Model Fertility Care System, couples can choose to either achieve or avoid pregnancy naturally, without the use of pharmaceutical contraceptives.

The Creighton Model Fertility Care System is based on tracking the day-to-day changes of a woman’s cervical fluid, or vaginal discharge that comes and goes with each menstrual cycle. This fluid indicates when a woman is fertile or infertile. By learning her normal pattern, a woman can also recognize what may be abnormal for her and see her doctor for medical care.


    • 100% natural and free from side effects 
    • 99% effective in avoiding pregnancy 
    • 76% effective in achieving pregnancy within a month 
    • Affordable—compared to costly contraceptives 
    • Both man and woman share in family planning 
    • Can be used at any stage of a woman’s reproductive life 
    • Effective for women with regular or irregular cycles 
    • Creates a valuable health record for women 
    • Increases intimacy and communication for couples 
Introductory Session (1 hour) - $30.00


The Carondelet Fertility Care Center provides a free, one-hour overview of the method during a introductory group session at our location. After this session, couples will have enough knowledge to begin charting daily changes in the woman's cycle. Long-distance instruction is available for out-of-town clients.

After the introductory session, the couple may continue to meet with a Certified Fertility Care Practitioner regularly throughout the year to ensure they’re progressing correctly.
