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.

7. Current Clinic Services and Profile
Current Name:   ART Clinic of the United States
Donor egg?	Yes	Gestational carriers?	Yes		SART member?		Yes
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 2002 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. See Figure 11.
	e	All ages (including ages >42) are reported together because previous data show that patient age does not materially affect success with donor eggs.
