Mature Reproductive Age

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

Mature reproductive age, in NaProTECHNOLOGY, refers to women age 35 and older who are pursuing pregnancy. The average age in Hilgers' described population is 37.9 years.⁷⁸ The term acknowledges the clinical reality of declining fertility potential with age without treating older maternal age as a barrier to restorative care.

NaProTECHNOLOGY diagnosis and treatment in this population focuses on identifying and correcting the underlying causes of subfertility. Outcomes reported in this group, including lower rates of multiple pregnancy, preterm birth, and low birth weight compared to published ART outcomes, reflect the diagnostic depth NaPro applies to couples who might otherwise receive a direct referral to assisted reproduction.⁷⁸
