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.

a Reflects patient and treatment characteristics of ART cycles performed using fresh nondonor egges or embryos.

b When fewer than 20 cycles are reported in a 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 42 or 44, depending on reporting year, 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 >42 or >44 depending on reporting year) are reported together because previous data show that patient age does not materially affect success with donor eggs.
