Granulocyte colony-stimulating factor for intracytoplasmic sperm injection patients with repeated implantation failure: which route is best?†

Clinicians should consider a combination of IU use before ovulation triggering with SC administration starting from the day of oocyte collection for using G-CSF for the treatment of recurrent implantation failure. Additionally, our data show the need for research in the field of administration route of G-CSF for RIF. We suggest that further studies be performed in this field.
