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 …
