Canadian Assisted Reproductive Technologies Registry (CARTR) is a registry where IVF clinics in Canada send their yearly results for compilation into a national average. In January 2013, CARTR merged with Better Outcomes Registry & Network (BORN) Ontario, the Ontario perinatal registry. This collaboration is enabling improvements in CARTR data collection, analysis, and reporting.
