Consistent Success

The Colorado Center for Reproductive Medicine (CCRM) is pleased to announce our 2013 IVF Success Rates/SART data along with our 2013 embryo comprehensive chromosome screening (CCS) results. We are proud to report over seven years of consistently high live birth rates and low miscarriage rates utilizing our embryo CCS technology testing for 23 pairs of chromosomes with cryopreservation. CCRM’s IVF success rates continue to be among the highest in the country.

The 2013 SART results vary from past years’ data due to the increased use of our embryo CCS technology with cryopreservation. SART’s IVF Success Rate Report does not include any planned “freeze all” cycles in its summary of “Fresh Embryos from Non-Donor Oocytes”. All embryo CCS cycles are planned “freeze all” cycles and the data can be found included in the “Frozen Embryo from Non-Donor Eggs”.

The following unpublished (by SART) CCS transfer statistics are provided for those who are interested in CCRM’s 2013 success rates with this technology.

a) Reflects patient and treatment characteristics of ART cycles performed in 2013 using fresh, non-donor eggs or embryos.
b) When fewer than 20 cycles are reported in an age category, rates are shown as a fraction and confidence intervals are not given. Calculating percentages from fractions may be misleading and is not encouraged.
c) A multiple infant birth is counted as one live birth.
d) Clinic-specific outcome rates for women older than 44 undergoing ART cycles using fresh or frozen embryos with nondonor eggs are not included because of small numbers. Readers are urged to review national outcomes for these age groups.
e) All ages (including ages >44) are reported together because previous data show that patient age does not materially affect success with donor eggs.
The above information was submitted to SART (Society for Reproductive Technology) in December, 2014 and are included in the 2013 national report as well as the Centers for Disease Control and Prevention (CDC) 2013 ART statistics.
Research cycles are included in SART data, not in CDC data, thus you will notice a difference in the SART and CDC data reports.
