What is NaProTechnology?

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.


NaProTECHNOLOGY, using CrMS as a foundation, can be used to treat many health issues, including the following:

· Infertility

· Repetitive miscarriage 

· Menstrual cramps 

· Premenstrual syndrome (PMS) 

· Ovarian cysts 

· Irregular or abnormal bleeding 

· Polycystic ovarian disease/syndrome (PCOS) 

· Postpartum depression 

· Prematurity prevention 

· Hormonal abnormalities 

· Chronic discharges

· Other health issues


NaProTECHNOLOGY was developed by Dr. Thomas Hilgers, who is currently a senior medical consultant in obstetrics, gynecology, and reproductive medicine and surgery at the Pope Paul VI Institute.  He is a clinical professor in the Department of Obstetrics and Gynecology at Creighton University School of Medicine, Omaha, Nebraska.

This groundbreaking documentary seeks to inform women of a natural alternative to mainstream women’s healthcare. The film takes a look at this new science while contrasting it with the more widely used medical model, and the highly problematic practice of prescribing hormonal contraceptives as a treatment for a wide array of women’s health issues
