2010 IVF Statistics


The Colorado Center for Reproductive Medicine (CCRM) is pleased to announce our 2010 SART data along with our increased take home baby rates per embryo transfer for all age groups from 35 to 44 years undergoing Comprehensive Chromosome Screening (CCS). What is particularly worth noting is the increase in the 41 to 42 year old women with CCS.  In 2009 17.0% of embryo transfers from fresh cycles resulted in a take home baby for 41 to 42 year olds, and in 2010, 48.7% of frozen embryo transfers following CCS resulted in a take home baby for this age group. With CCRM’s latest addition of comprehensive chromosome screening our success rates continue to be among the highest in the nation.

Following the 2010 CCS Data below is the CCRM 2010 Clinic Summary Report which was submitted to the Society for Assisted Reproductive Technology (SART).  SART does not include any planned freeze all cycles in its summary of “Fresh Embryos from Non-Donor Ooocytes” which means CCRM’s egg retrievals for Comprehensive Chromosome Screening (CCS) are not included in the 2010 SART data below.

The following unpublished (by SART) CCS statistics are provided for patients who are interested in CCRM’s 2010 success rates with this technology.  In 2010 the Colorado Center for Reproductive Medicine did 389 retrievals on patients planning to have an “embryo freeze all” cycle, as the patients were having their embryos tested for 23 pairs of chromosomes through Comoprehensive Chromosome Screening (CCS) technology.  Upon the completion of the CCS testing, CCRM did 251 frozen embryo transfers for CCS patients with chromosomally normal embryos.  Some patients having egg retrievals in 2010 will not have their frozen embryo transfers until 2011.  The following is the data from the 2010 CCS transfer patients:

a) Reflects patient and treatment characteristics of ART cycles performed in 2010 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, 2011 and will be included in the 2010 national report as well as the Centers for Disease Control and Prevention (CDC) 2010 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.
