Sample Clinic Table of the 2010 ART Report

Back to How to Read a Fertility Clinic Table

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.

IVF >99% Procedural Factors: Tubal factor 13% Other factor 7%

Donor embryo? Yes Cryopreservation? Yes Verified lab accreditation? Yes
Single women? No (See Appendix C for details.)

a—Reflects patient and treatment characteristics of ART cycles performed in 2010 using fresh nondonor 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.

e— All ages (including ages >44) are reported together because previous data show that patient age does not materially affect
success with donor eggs.
