Epidemiologic Approaches for Studying Assisted Reproductive Technologies: Design, Methods, Analysis and Interpretation.

PURPOSE: While considerable progress has been made since the advent of assisted reproductive technology (ART), the field remains a complex and challenging one for clinicians and researchers alike. This review discusses some of the most salient issues pertaining to the study of ART and whenever possible suggestions on how to address them.

RECENT FINDINGS: More than 5 million babies have been born through ART to date, representing up to 4% of all births worldwide. While technologies continue to evolve and demand for treatment grows, it is more important than ever to conduct rigorous and timely research to help guide clinical practice that is safe and effective, and that minimizes potential short- and long-term adverse outcomes to mother and child.

SUMMARY: ART research will require exceedingly more sophisticated research methods, designs, and analyses that are rooted in a reproductive epidemiological framework in order to improve future research and ultimately promote better outcomes for all subfertile couples and their children.
