NaProTECHNOLOGY vs. RRM

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

NaProTECHNOLOGY (NaPro) is the most established and studied approach within restorative reproductive medicine, developed by Dr. Thomas Hilgers at the Pope Paul VI Institute and based on the Creighton Model. RRM is a broader category describing approaches that share the restorative philosophy. NaPro practitioners may or may not identify their work under the RRM label. Other approaches that share this philosophy include: NeoFertility, Marquette Method-based medical management, FEMM-based care, and various symptothermal or sympto-hormonal approaches. All share the common framework of using biomarker data from cycle charting to optimize normal reproductive function.¹
