Welcome to the Home of FertilityCare and NaProTechnology!

The Saint Paul VI Institute is the only medical Institute of its kind that specializes in research, diagnosis, and treatment of procreative and women’s healthcare within a pro-life ethic.

National Center for Women’s Health

National Center for Women's Health (NCWH)

The National Center for Women’s Health provides cooperative medical and surgical treatments with the Creighton Model FertilityCare™ System, NaProTechnology®, and Pelvioplasty.

Tens of thousands of patients from all 50 states (and many countries) have received our internationally respected healthcare services in Omaha, NE, USA.

Over 4,000 ovulation cycles have been studied by ultrasound at the Institute — more than any other single program in the world.

Our National Hormone Laboratory specializes in studies of nearly every reproductive hormone. The standardized Creighton Model charting gives insights that are otherwise not tested for.

Education and Research

Since 1976, our research has explored new methods for treating infertility and other women’s health conditions — including over 238 professional books, book chapters, poster sessions, peer-reviewed medical articles, videos, and other presentations.

Over 30 obstetrician-gynecologists have been trained through the St. John Paul the Great Fellowship in Medical & Surgical NaProTechnology.

Thousands of Practitioners, Supervisors, Educators, and Medical Consultant physicians from all 50 states and six continents have been trained through our Health Education Programs.

Over 50 years after the introduction of the birth control pill, medical science has made little attempt to understand fertility and the menstrual cycle. Women’s healthcare today focuses on masking abnormal symptoms and problems. This results in medical practices such as in vitro fertilization, which makes new life by destroying life. Thomas W. Hilgers, MD is Director of the Institute’s Academic Programs and its National Center for Women’s Health. In 1968, Pope Paul VI presented Catholic Church teachings on love and life in the encyclical Humanae Vitae. At that time, natural methods of fertility regulation were insufficient for couples to live these teachings effectively and joyfully. This challenge prompted Dr. Hilgers to begin scientific research in natural fertility regulation. His research brought forth the revolutionary Creighton Model FertilityCare System and the new women’s health science of NaProTECHNOLOGY®.

Pivotal discoveries of the Saint Paul VI Institute

Creighton Model FertilityCare™ System (CrMS)

One of Dr. Hilgers’ pivotal discoveries is the standardized observation of menstrual and fertility cycles, known as the CrMS. Women chart with the system for gynecologic health maintenance, and couples use it to achieve or avoid pregnancy.

Trained physicians can read a woman’s CrMS chart universally — this is the key to unraveling the mysteries of the menstrual and fertility cycle.

Natural Procreative Technology (NaProTechnology®)

NaProTechnology is a researched and published women’s health science based on CrMS observations, which provides objective information on the cycle. After using the CrMS to telegraph abnormalities, NaProTechnology treats problems cooperatively with the procreative and gynecologic systems while respecting the dignity of women, couples, and pre-born children.

Pelvioplasty is a surgical technique, developed at the Saint Paul VI Institute, which eliminates, for the most part, the scar tissue that forms following surgery done in the removal of endometriosis and other surgeries. The Saint Paul VI Institute has now become the “Home of Pelvioplasty.”


“We were so grateful for an answer to our otherwise diagnosed ‘unexplained infertility’ … [The physicians and staff of the Institute] focused on the whole picture of gynecological health and wellness, an avenue of care I felt many previous medical professionals had failed to provide.”

— Alyssa Paulsen, Saint Paul VI Institute patient

“It is so very clear to me that this work, this mission, impacts so many lives. I tell my students that every ounce of energy they put into this work will bless them 10 fold, 100 fold, 1000 fold!”

— Alia Keys, Certified FertilityCare Educator

“I can help [families] with FertilityCare before problems get started. Through an appreciation for their fertility, they make better decisions regarding sexuality.”

— Johnny Voltz, MD, Class 40 Education Program Student
