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.
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.
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).
GCSF can improve pregnancy outcome in patients with history of implantation failure.
