Effectiveness of NaProTECHNOLOGY®

The effectiveness of NaProTECHNOLOGY® is very high. With the use of the Creighton Model FertilityCare™ System alone, which enables accurate identification of the fertile window, conception occurs in 20% to 40% of infertile couples (when charting is continued for 6 to 12 months, respectively).

When NaProTECHNOLOGY® is combined with the Creighton Model—that is, when appropriate medical treatment is implemented and intercourse occurs during the correctly identified fertile period—pregnancy occurs in 44% to 71% of infertile couples (when treatment continues for 12 to 24 months, respectively).
