Abstract: (241 Views)
Introduction: The majority of embryo transfers (ETs) to date have been performed on day 3 to reduce the potential risk of fetal growth arrest. Transfer on day 5 provides higher clinical pregnancy outcomes with reduced risks of multiple pregnancies. This study aimed to evaluate the pregnancy outcome between day 5 embryo transfer and day 4 fresh embryo transfer in patients undergoing intracytoplasmic sperm injection (ICSI).
Materials and Methods: This study was conducted at the Infertility Research Center of Sarem Hospital, Tehran, in 1402 on 921 infertile women who had been referred for ICSI. These patients were assigned to receive fresh embryo transfer (n=163) and blastocyst stage transfer (n=758). Statistical analyses were performed using SPSS software.
Conclusion: There was no significant difference between the two groups in terms of mean age and pregnancy rate. The pregnancy rate on the fourth day (31.29%) was similar to that on the fifth day (28.50%) (PV <50.0). However, there was a significant difference between the two groups in terms of embryo quality (PV<0.05).
