a Reflects patient and treatment characteristics of ART cycles performed in 2004 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 are unreliable for women older than 42 undergoing ART cycles using fresh or frozen embryos with nondonor eggs. Readers are urged to review national outcomes for these age groups.
eeAll ages (including ages >42) are reported together because previous data show that patient age does not materially affect success with donor eggs.
