CEIBA: Creighton Model Effectiveness, Intentions, and Behaviors Assessment
The Creighton Model FertilityCare System (CrM) is the most standardized and medically developed method of natural family planning in the United States. It is based on the observations of biomarkers of the menstrual cycles, particularly vaginal bleeding and cervical fluid. It can be used in all reproductive situations including regular, irregular, or absent menstrual cycles. The primary goal of the CEIBA study is to assess the effectiveness of the CrM to avoid pregnancy with newer statistical methods, and in the context of motivations, intentions, and behaviors of the participating couples during its use. The study is observational in nature and does not involve any blood tests or medications.
