NaProTECHNOLOGY vs. RRM

By RRM Academy Reviewed by Dr. Naomi Whittaker, MD, Board-Certified OBGYN, MIGS, NFPMC, FCI Updated May 11, 2026

NaProTECHNOLOGY (NaPro) is the most established and extensively studied approach within Restorative Reproductive Medicine, developed by Dr. Thomas Hilgers at the Pope Paul VI Institute and built on the Creighton Model FertilityCare System. RRM is the broader paradigm: it describes any medical approach that diagnoses and treats the root causes of reproductive dysfunction in cooperation with normal physiology, without bypassing or suppressing it. NaPro practitioners may or may not identify their work under the RRM label. Other approaches sharing this philosophy include: NeoFertility, Marquette Method-based medical management, and FEMM-based care. All share a common framework: biomarker data from cycle charting guides cycle-timed evaluation, root-cause diagnosis, and restorative treatment. None use suppressive medications as primary therapy or bypass conception through assisted reproductive technology.¹
