Time to Pregnancy (TTP)

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

The number of menstrual cycles or months required to achieve a clinical pregnancy in a couple attempting conception. In the general fertile population, approximately 80% of couples conceive within six cycles and 90% within twelve cycles. TTP is an important framing concept in RRM: procedural approaches are often reported as per-cycle success rates, whereas RRM is evaluated by cumulative outcomes across the full course of diagnosis and treatment. Published NaProTECHNOLOGY cohort studies report cumulative live-birth rates at 24 and 36 months, reflecting the restorative time horizon in which underlying conditions are corrected and fertility resumes naturally.¹⁰¹¹
