RSC Success Rates

We are proud to report a 45 percent pregnancy rate per egg retrieval. That translates into 644 pregnancies in 2005, the year for which we have the most recent statistics.

Our superior pregnancy rates are one reason RSC is nationally recognized, along with a state-of-the-art facility. Pregnancy rates for all ART programs in the US are available from the Centers for Disease Control and Prevention (CDC) www.cdc.gov.

Understanding Success Rates

Because there are many ways to measure and compare success, published success rates for assisted reproductive technologies can often be misunderstood and misleading. Clearly, the most important measure of success is the percentage of couples who initiate treatment and ultimately take home a baby. However, because there are three stages to an ART treatment, and not every couple reaches every stage of treatment, success can be measured in three different ways.

• Clinical Pregnancy Rate per Cycle Initiated - is the number of clinical pregnancies divided by the total number of women who initiated treatment.
• Clinical Pregnancy Rate per Retrieval - is the number of clinical pregnancies divided by the number of retrievals. Not all women who initiate a cycle have a retrieval. Some ART cycles initiated are canceled, mostly due to a poor response to fertility drugs.
• Clinical Pregnancy Rate per Transfer - is the number of clinical pregnancies divided by the number of women who had an embryo transfer. Not all women who have a retrieval have an embryo transfer.

Note: A clinical pregnancy is defined as the presence of one or more gestational sacs (with a beating heart) in the woman's uterus, confirmed by ultrasound examination.

Keep in mind, however, that while most ART providers report success rates based on clinical pregnancy, these statistics do not accurately reflect the number of women who ultimately take home a baby. A certain number of patients who achieve pregnancy have a miscarriage, for example.

Clinical Quality Improvement Program

Since 1995, we have been working as a multidisciplinary team of dedicated professionals to continuously improve our pregnancy rates. Our clinical pregnancy rates per transfer since 2000 have been consistently above 50 percent.

At the Reproductive Science Center, our Clinical Quality Improvement Program has allowed us to improve our pregnancy rates while simultaneously reducing the potential for multiple births! That's an example of why our clinical results are highly regarded.

• A comparison of clinical success rates may not be meaningful because patient medical characteristics and treatment approaches may vary from clinic to clinic.
