NaProTECHNOLOGY (Natural Procreative Technology)

By RRM Academy Reviewed by Dr. Naomi Whittaker, MD, Board-Certified OBGYN, MIGS, NFPMC, FCI Updated May 7, 2026

A specific women's health science focused on reproductive and gynecologic health, developed by Dr. Thomas Hilgers at the Pope Paul VI Institute. It utilizes the Creighton Model FertilityCare System for precise cycle monitoring to guide targeted medical (NaPro Medical) and surgical (NaPro Surgery/Advanced Reproductive Surgery) treatments based on identified cycle abnormalities. NaProTECHNOLOGY works cooperatively with the reproductive system and does not employ methods that are inherently suppressive, circumventive, or destructive. In Hilgers (2004), a cohort of 1,045 infertile patients reported cumulative live-birth rates exceeding 60% by 24 months and approximately 70% by 36 months.¹⁰ More recently, Sanchez-Mendez et al. (2025) followed 1,310 couples and reported cumulative live-birth rates of 50% at 24 months and 62.1% at 36 months or longer.¹¹¹² Both figures are comparable to or higher than cumulative live-birth rates achieved after one or more IVF cycles
