National ART Success Rates

To Fertility Clinic Success Rates
 

   
2011 NATIONAL SUMMARY

A Comparison of clinic success rates may not be meaningful because patient medical characteristics and treatment approaches vary from clinic to clinic.   For more details about this, along with information on how to interpret the statistics in this table, see Introduction To Fertility Clinic Success Rates.

CURRENT CLINIC SERVICES AND PROFILE Total Number of reporting clinics:  451
Percentage of Clinics that offer the following services: Clinic Profile:
Donor egg 93% Gestational Carriers 86% SART Member 84%
Donor embryo 71% Cryopreservation 100% Verified lab accreditation
Single women 95%    Yes 93%
   No 6%
   Pending 1%

a Reflects features of fresh nondonor cycles. If IVF is <100%, the remaining cycles are GIFT, ZIFT or a combination of these procedures with IVF.
b Total patient diagnosis percentages may be greater than 100% because more than one diagnosis can be reported for each cycle.
c A multiple-infant birth is counted as one live birth if at least one infant is live born.
d Number excludes 11,116 oocyte/embryo banking cycle(s) and 6 cycles in which new procedures were evaluated.
e All ages are reported together because previous data show that patient age does not materially affect success with donor eggs.
