Pregnancy Rates and OBRS Database Services

The average success rate for all in vitro fertilization procedures in the US is approximately 25-30%.  By contrast, at SIRM, the average IVF success rate is 50-60%, so our centers are considerably above average - even though we don't turn away patients that have been unsuccessful at other centers.  Your individual chance for success is based upon your specific medical history, age and other factors which will be discussed with you by your doctor during your consultation.

Pregnancy Rates

In spite of numerous attempts over a period spanning more than 2 decades, on the part of our governing bodies, the American Society of Reproductive Medicine (ASRM) and the Society for Assisted Reproductive Technology (SART), to come up with a verifiable reporting system of IVF outcomes, there is still currently no system in place to verify the authenticity of reported clinic-specific ART outcome statistics. The so-called SART report, published annually on the website of the Centers for Disease Control (CDC), does not provide verifiable results, does not allow for any comparison between complex (difficult) and straight-forward IVF cases, and is often reported two years after treatment. This has led to a total lack of confidence in reported data and is one of the reasons why insurance companies are reluctant to reimburse for IVF services.

OBRS Database Services

SIRM has developed an IVF Outcome Based Reporting System (OBRS) which provides reliable IVF outcome data presented in categories of age each of which is further subdivided into 4 subgroups (A-D) based on relative Categories of Complexity (as defined in the table below), using several important variables that are known to influence outcome. Ovum donation and frozen embryo transfers (FET) results are reported separately in the same table.

OBRS ensures accurate representation of all cases undergoing embryo transfer (the denominator of outcome) for statistical computation. The outcomes are updated regularly to ensure that all ongoing pregnancies (beyond the 1st trimester) are accurately represented.

We hold that it is only through a process such as OBRS that it is possible, against the background of relevant demographic, clinical, and laboratory variables (that affect IVF outcome) to verifiably present statistics in a manner that permits reasonable case to case comparison without having to compare apples with oranges.
