Background: Although pregnancy rate in in vitro fertilization-embryo transfer (IVF-ET) cycles has been increased over the preceding years, but the majority of IVF-ET cycles still fail. Granulocyte colony stimulating factor (GCSF) is a glycoprotein that stimulates cytokine growth factor and induces immune system which may improve pregnancy rate in women with history of implantation failure.
Objective: The aim of this study was to evaluate GCSF ability to improve pregnancy rate in women with history of implantation failure.
Materials and methods: 0.5 ml (300 µg/ml) GCSF was infused intrauterine in intervention group. Pregnancy outcomes were assessed based on clinical pregnancy.
Results: The mean age of participants was 31.95±4.71 years old. There were no significant differences between demographic characteristics in two groups (p>0.05). The pregnancy outcome in GCSF group was improved significantly (p=0.043).
Conclusion: GCSF can improve pregnancy outcome in patients with history of implantation failure.
