Clear answers about the Creighton Model, NaProTECHNOLOGY, and how to take the first step.

Frequently asked questions
Is the Creighton Model a calendar-based method?
No. Unlike calendar-based methods, it doesn't estimate fertile days from past cycles. It teaches you to observe and record your own cycle's biomarkers in real time — such as the bleeding pattern and cervical mucus — using standardized criteria. It doesn't guess the cycle: it observes it, records it, and interprets it.
Learn about the Creighton methodDo I need to be married or in a relationship to learn the Creighton Model?
No. Any woman of reproductive age can learn to understand her cycle to care for her health. When there is a partner, he can join the process; and when relevant, the man's reproductive health is considered too.
Is the Creighton Model only useful for trying to get pregnant?
No. It's useful for understanding and caring for reproductive health, monitoring the cycle, and making decisions with more information — whether to try for pregnancy or to postpone it, according to the system's criteria. It also provides useful data for symptoms like pain, irregular bleeding, or altered cycles.
What's the difference between the Creighton Model and NaProTECHNOLOGY?
The Creighton Model is the educational part: it teaches you to observe and chart your cycle. NaProTECHNOLOGY is the medical part: using that information, a physician can look for the causes of a disorder and guide testing or treatment.
Learn about NaProTECHNOLOGYDoes NaProTECHNOLOGY guarantee a pregnancy?
No. No intervention can guarantee that. NaProTECHNOLOGY seeks to restore the health conditions that allow fertility to express itself naturally when possible. Every process is unique and results can vary.
