In Vitro Fertilization Process: Success Rates

Individual statistics will be discussed with each couple prior to beginning an in vitro fertilization cycle. Institutional statistics are not directly applied to individuals.

An institution gathers their information over a period of time from all of their patients and compiles this information. The statistics gathered in such a manner are for populations of people and not individuals specifically.

When choosing a program that is right for you be sure to consider the entire program and not just numbers. Other important factors include the personnel, location, experience, and services provided.

Both the Centers for Disease Control (CDC) and the Society for Assisted Reproductive Technology (SART) issue statements advising patients and physicians not to use statistics as a means of comparing programs.

There are several reasons why this is true. SART data, for example, do not take into account factors such as practice patterns, numbers of embryos transferred, number of attempts per individual, and cancellation criteria.
