Repeated Subcutaneous Granulocyte Colony Stimulating Factor Effect in Clinical Pregnancy Rate
Abstract
Background: One of the most important challenges to the mother during pregnancy is the implantation of a semi-allogenic fetus. Granulocyte Colony Stimulating Factor is a polypeptide glycoprotein mainly used in hematological diseases and post-chemotherapy, but it has recently gained some popularity as an immune-modulating agent in reproductive medicine. The study aimed to define the influence of repeated subcutaneous G-CSF administration in infertile females submits to intracytoplasmic sperm injection.
Method: Ninety patients were taken from an outpatient infertility clinic and divided into two groups on the day of embryo transfer. The control group (49 patients) received no extra intervention, while the G-CSF group (41 patients) received a subcutaneous injection of G-CSF the first hour after embryo transfer, followed by weekly injections until a positive fetal heartbeat was detected.
Result: In the G-CSF group, the implantation rate was 20.4% compared to 7.6% in the control. In the control group, the rates of both chemical and clinical pregnancy were 18.4%, whereas they were 48.8% and 43.9%, respectively, in the G-CSF group.
Conclusion: The multiple doses of G-CSF significantly improved the implantation and pregnancy rates, so it is considered a promising drug in reproductive medicine.
