Troché Fertility Centers's Success Rates
Troché Fertility Centers have an "open door" policy that does not select, restrict or discourage patients from ART procedures. We have found that for some patients it is helpful to proceed with an ART procedure even when their chances for success are extremely low. This allows them to find closure and empowers them to choose what could be a more successful option (egg donation or adoption). Prior to an ART procedure all patients know what their chances for success are and what other treatment options are available to them.

At Troché Fertility Centers the average number of embryos transferred has been steadily decreasing. For the 2010 reporting year the average number of embryos transferred to women < 35 years old was 2.3 embryos, which is quite less than in 2008 when we transferred an average of 2.6 embryos. Troché Fertility Centers follows the guidelines of the American Society of Reproductive Medicine (ASRM) regarding the number of embryos transferred during In Vitro Fertilization. Nevertheless, we use these guidelines in combination with each patient’s particular characteristics in deciding how many embryos to transfer. Which means that on occasion we may exceed the recommendations of the ASRM.
Please note: A comparison of clinic success rates may not be meaningful because patient medical characteristics, treatment approaches and entrance criteria for ART may vary from clinic to clinic.

About Fertility Treatment Success Rates
-
The Society for Assisted Reproductive Technology (SART) is an organization of ART providers affiliated with the American Society for Reproductive Medicine (ASRM). Since 1989 SART has been collecting data and publishing annual reports of pregnancy success rates for fertility clinics in the United States and Canada. In 1992, the U.S. Congress passed the Fertility Clinic Success Rate and Certification Act. This law requires the Centers for Disease Control and Prevention (CDC) to publish pregnancy success rates for ART in fertility clinics in the United States. In 1995, the CDC in consultation with SART and ASRM started to report the ART success rates. Troché Fertility Centers is a member of SART and has been reporting its ART success rates to CDC through SART since our laboratory became operational in 1997.
The goal of these reports is to help you as a potential patient make informed decisions about ART by providing information about what your chances are of having a child with fertility treatment, and where you can go for treatment. Many people considering IVF and related procedures use the published ART success rates to find the "best" fertility center. However, comparisons between clinics must be made with caution since many factors contribute to the success of an ART procedure. Some factors are related to the training and experience of the fertility doctor, the laboratory professionals, and the quality of services they provide. Other factors are related to yourself as a patient, such as your age and the cause of your infertility. Some centers may be more willing than others to accept and offer ART to couples with low chances of success, or may see more than the average number of patients with difficult infertility problems. These centers may have lower pregnancy rates than centers that discourage such patients or encourage them to use donor eggs which results in higher success rates among older women.
