Aims: The aim of this study is to compare cumulative in vitro fertilization-intracytoplasmic sperm injection outcomes following two elective single embryo transfer (eSET) versus one double embryo transfer (DET) using blastocyst(s). Settings and Design: This was retrospective observational study. Study Period: The study was conducted during January 2015–December 2015. Subjects and Methods: Forty-one fresh + 25 frozen eSET versus 123 DET using self-oocytes and 68 fresh + 35 frozen eSET versus 184 DET using donor-oocytes were included in the study. All failing to achieve live birth after first eSET underwent frozen embryo transfer cycle with second blastocyst. Cumulative outcome after two eSET were compared with one DET. Statistical Analysis Used: The analysis was performed by Chi-square and t-test. Results: In self-oocytes group, higher but statistically nonsignificant cumulative clinical pregnancy rate (CPR) (58.5% vs. 57.7%, P = 0.92) and live birth rate (LBR) (48.7% vs. 44.7%, P = 0.65) with significantly lower multiple pregnancy rate (MPR) (4.2% vs. 45%, P = 0.0002) were obtained; whereas in donor-oocytes group, comparable cumulative CPR (73.5% vs. 65.7%, P = 0.24), significantly higher LBR (64.7% vs. 48.9%, P = 0.02) and significantly lower MPR (4% vs. 51.2%, P = 0.00005) were obtained after two eSET vs. one DET. In self-oocytes group, the incidence of prematurity (10% vs. 21.4%, P > 0.05) and low birth weight (25% vs. 45.6%, P > 0.05) were lower but statistically nonsignificant, whereas in donor-oocytes group, incidence of prematurity was lower but statistically nonsignificant (26.7% vs. 38.8%, P > 0.05) while of low birth weight was significantly lower (32.7% vs. 51.2%, P = 0.0038) after two eSET versus one DET. Conclusion: Cumulative LBR was higher with lower incidence of multiple births, prematurity and low birth weight after two eSET versus one DET using self- or donor-oocytes. Higher use of eSET improves reproductive outcomes in patients with good prognosis.
