A retrospective review of 237 initial, fresh nondonor IVF cycles in which all embryos generated during the cycle were transferred on either day 2 (n = 109) or day 3 (n = 128) were evaluated with regards to reproductive outcomes. Patients who underwent a day 2 ET had similar conception (18% vs. 16%; relative risk [RR], 1.1; 95% confidence interval [CI], 0.64-1.95), clinical pregnancy (13% vs. 16%; RR, 0.8; 95% CI, 0.44-1.55), implantation (6% vs. 7%; RR, 0.9; 95% CI, 0.50-1.68), and live-birth (10% vs. 16%; RR, 0.7; 95% CI, 0.32-1.29) rates as those who underwent a day 3 ET.
