2003 Assisted Reproductive Technology (ART) Report: Sample Clinic Table

A comparison of clinic success rates may not be meaningful because patient medical characteristics and treatment approaches vary from clinic to clinic.
2003 ART Cycle Profile
1. Type of ART ^a			2. Patient Diagnosis
IVF	>99%	Procedural Factors:		Tubal factor	13%	Other factor	7%
GIFT	<1%	With ICSI	53%	Ovulatory dysfunction	6%	Unknown factor	10%
ZIFT	<1%	Unstimulated	<1%	Diminished ovarian reserve	9%	Multiple Factors:
Combination	<1%	Used gestational carrier	<1%	Endometriosis	6%	Female factors only	13%
				Uterine factor	1%	Female & male factors	18%
				Male factor	17%

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 2003 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.
