Use of G-CSF for the Treatment of Unexplained Recurrent Miscarriage

In order to investigate the effectiveness of G-CSF in preventing embryo demise, the investigators administered this cytokine to women with recurrent miscarriage in a randomized controlled study compared to women treated with placebo. Sixty eight women with unexplained primary recurrent miscarriage, all of them with at least four consecutive abortions and negative for all clinical investigations were selected for this study. Patients were randomly treated with G-CSF, starting on the 6th day after ovulation, or with placebo.
