Efficacy of uteral injection of G-CSF in repeated implantation failure: A clinical trial study

Despite advances in clinical and laboratory techniques, including stimulating ovulation and transferring embryo, success rate of pregnancy remains is about 30%. The aim of this study was to assess the effect of intra uterine G-CSF on implantation and clinical pregnancy rate in patients with implantation failure in IVF.
This study was a randomized clinical trial on patients undergoing in vitro fertilization within an age range of 45-18 years and a history of failure in implantation for two or more times. A total of 34 patients receiving G-CSF in the intervention group and 38 patients in the control group were enrolled.
Mean age of the participants was 34.1 years with a standard deviation of 6.4 years. The average number of years of fertility was 10 years with a standard deviation of 5.2 years. The average number of embryos implanted in the intervention group was 2.88 with a standard deviation of 0.33. The figures for the control group were 2.97 and 0.37, respectively. The two groups did not differ significantly. With respect to the potential clinical and laboratory fertility outcomes, including existing gestational sac with observed heart rate and positive serum βHCG, no statistically significant difference was observed between the two groups.
It seems that the effect of G-CSF on improving fertility outcomes in patients with implantation failure does not exist and more related studies are recommended in this regard.
