This study was done to compare uterine artery and sub-endometrial blood flow indices during the luteal phase between patients with unexplained recurrent abortion and fertile women and also to evaluate the effects of nitric oxide donors on blood flow indices in the abortion gr...

Women with recurrent abortion, primary unexplained infertility, and gestational trophoblastic neoplasia (GTN) manifest disordered human chorionic gonadotrophin (HCG) secretion. Mutations in the HCG beta/luteinizing hormone (LH) beta gene complex could cause aberrant HCG production in these disorders. The purpose of this study was to determine whether HCG beta gene deletions occur in women with ...

Antithyroid antibodies, parvovirus B19 (B19V) and cytomegalovirus (CMV) infections, which were usually overlooked in clinical practice of handling cases of recurrent abortion, were studied to evaluate their role in the pathogenesis of recurrent first trimester...

Background Effects of GCSF (Granulocyte Colony-stimulating Factor) injection in patients suffering from recurrent pregnancy loss has been studied in some studies and we now know that transvaginal perfusion of G-CSF might be helpful for improvement of implantation rate among patients with thin endometrium and patients under in vitro fertilization /embryo transfer (IVF/ET) or intracytoplasmic spe...
