Based on over thirty years of research and practical application, NaProTECHNOLOGY (Natural Procreative Technology) is a women's health science which has, as its main principle, the ability to work cooperatively with the woman's menstrual and fertility cycle. NaProTECHNOLOGY relies on the CREIGHTON MODEL FertilityCare System (CrMS)biomarkers to monitor easily and objectively the occurrence of various hormonal events during the menstrual cycle. CrMS provides valid information that can be interpreted by a woman and by physicians who are specifically trained in this system.

NaProTECHNOLOGY is the first women's health science to network family planning with reproductive health monitoring and gynecologic health maintenance unlike common artificial and suppressive approaches. This is a fertility-care based medical approach rather than a fertility-control approach that provides medical and surgical treatments.

NaProTECHNOLOGY identifies the problems and cooperates with the menstrual and fertility cycles that correct the condition, maintain the human ecology, and sustain the procreative potential. It has many applications, including family planning, the evaluation and treatment of infertility and other reproductive disorders, abnormal bleeding, abnormal hormone conditions of the menstrual cycle including premenstrual syndrome and recurrent ovarian cysts, the dating and beginning of pregnancy, and postpartum depression. 




What is the difference between NaProTECHNOLOGY® and the Creighton Model FertilityCare™ System?

How does NaProTECHNOLOGY® work?

The Creighton Model FertilityCare™ System helps women monitor their naturally occurring phases of fertility and infertility. NaProTECHNOLOGY® is a medical science focused on women’s gynecological and procreative health that relies on insights revealed through the systematic observations inherent in the Creighton Model FertilityCare™ System. In this way, the two form an integrated network of fertility monitoring and gynecological healthcare that centers on couples’ procreative decisions and women’s individual medical needs. 

Creighton teaches women how to observe and chart their fertility cycles in a precise and standardized way. The chart then provides medically significant information that can be interpreted by physicians who are specifically trained in NaProTECHNOLOGY®. After analyzing the chart the NaProTECHNOLOGY®-trained doctor will be able to suggest appropriately timed diagnostic tests and provide women with valuable healthcare information and treatment options. The Creighton Model FertilityCare™ System is the only family planning method that can be used in conjunction with NaProTECHNOLOGY® to help diagnose and treat reproductive health problems. The Creighton chart provides unique insight into a woman’s cycle and helps to reveal significant aspects of her overall gynecological health.

NaProTECHNOLOGY® provides medical and surgical treatments for gynecological and reproductive disorders that many women face. NaProTECHNOLOGY® refuses to take any suppressive or destructive approaches. Instead, it works cooperatively with women’s reproductive and gynecological systems, maintaining the human ecology and sustaining procreative potential. NaProTECHNOLOGY® avoids merely masking symptoms and taking a “quick-fix” approach but seeks to identify an underlying issue and target the source of the disease.
