Abstract

Background: The use of assisted reproductive technology (ART) is increasing in the world. The rate, efficacy and safety of ART are very different among countries. There is an increase in the use of intra cytoplasmic sperm injection (ICSI), single fresh embryo transfer (ET) and frozen-thawed embryo transfer (FET).
Objective: The objective of this study was to compare pregnancy rate in fresh ET and FET.
Materials and Methods: In this retrospective cross-sectional study 1014 ICSI-ET cycles (426 fresh ET and 588 FET) from 753 women undergoing ICSI treatment referred to Fatemezahra Infertility and Reproductive Health Research Center in Babol, Iran from 2008 to 2013 were reviewed.
Results: There were no significant differences between biochemical pregnancy rate (23% versus 18.8%, OR 1.301; 95% CI .95-1.774), gestational sac (95.6% versus 100% in FET, OR 0.60; 95% CI 0.54-0.67), and fetal heart activity (87.2% versus 93.6% OR .46; 95% CI .16-1.32) in fresh ET and FET cycles, respectively. P< 0.05 was considered statistically significant for all measures.
Conclusion: Although, the result showed no significantly difference between the fresh ET and the FET cycles, however the embryos are able to be stored for subsequent ART. Therefore, we recommend FET cycles as an option alongside the fresh ET.
