International NaProTechnology Evaluation and Surveillance of Treatment for Infertility and Miscarriage (iNEST)

NaProTechnology (NPT) is a treatment option for infertility or miscarriage that identifies issues in a couple's fertility and fixes them to the extent possible by medical intervention. An important part of NPT is teaching couples to monitor the signs and symptoms of the woman's fertility cycle (menstrual cycle) with the Creighton Model FertilityCare System (CrMS). The purpose of the study is to look at outcomes among couples who consider or get NPT treatment to help them have a live birth. Results from the study will be used to answer questions such as: How many couples who use NPT get pregnant and have a baby? How can NPT treatment be improved? Does NPT treatment have fewer long-term health risks for the resulting children than other fertility treatments? What types of characteristics or environmental exposures influence whether NPT will be successful for a specific couple? To be eligible for the iNEST study, a couple must have a consultation with a NPT-trained clinician who is participating in iNEST.
