NOTES: CDC defines ART procedures as those that involve surgically removing eggs from a woman’s ovaries, combining them with sperm in the laboratory, and returning them to the woman’s body or donating them to another woman. ART procedures do not include treatments in which only sperm are handled (i.e., intrauterine or artificial insemination) or procedures in which a woman only takes medicine to stimulate egg production without the intention of having eggs retrieved from the ovaries. ART is more appropriately considered a cycle of treatment rather than a procedure at a single point in time because ART consists of several steps over an interval of approximately 2 weeks. All ART cycles that were intiated, even those that were discontinued before all steps were completed, are included in this analysis. Cycles in which a new type of treatment was being evaluated are excluded.
