Two hundred females with history of recurrent implantation failure and undergoing Intracytoplasmic Sprem injection (ICSI) were randomized into two groups; the first group (100 patients) received intrauterine Granulocyte colony stimulating factor (GCSF) and the second group (100) received intrauterine Human Chorionic Gonadotropin (HCG) at ovum pick up day. The clinical pregnancy rate was evaluated as a primary outcome after 14 days and ultrasound imaging of gestational sac was evaluated as a secondary outcome after 6 weeks.
Intrauterine Granulocyte colony stimulating factor (GCSF) was compared with intrauterine Human Chorionic Gonadotropin (HCG) in increasing clinical pregnancy rate as a primary outcome and ultrasound imaging of gestational sac as a secondary outcome.
