Reproductive Partners Medical Group, Inc. (as the Center for Advanced Reproductive Care and University Infertility Associates) has reported results since statistics were first compiled. We have reported, first to the Congressional survey, then the IVF Registry of the Society for Assisted Reproductive Technology (SART) and now report to the SART/CDC reporting system. Federal law now mandates such reporting. Because the type and age of patients treated may vary from program to program, the comparison of cycle statistics is complex. Couples should be aware of differences among programs as well as differences in specific characteristics when reviewing the data. There are a number of factors to keep in mind when reviewing data.

• Comparison of programs is complicated.

• Only annual data should be quoted since short-term trends are unreliable.

• Outcomes should be reported clearly in terms of live births per cycle, retrieval or transfer.

• Success rates reported in the SART/CDC Data Registry format cannot be compared to programs which do not report to SART/CDC since non-reporters may utilize formats designed to inflate their success rates.

The following are our results as reported to the SART/CDC reporting system. In order to get a long-term view of our results we are presenting cumulative reports from one, six and ten years. In the case of the La Jolla center, results are reported from their inception in 1998, one and six years.

As entry criteria are highly variable for each program, and treatment processes vary, a center-by-center comparison of results is not meaningful.
