BACKGROUND Repeated in vitro Fertilization (IVF) failure together with Ovarian Hyperstimulation Syndrome (OHSS) is one of the distressing situations leading couples to search for alternative treatment options. For such patients with Polycystic Ovarian Syndrome (PCOS) who have experienced Ovarian Hyperstimulation Syndrome, mild ovarian stimulation with in vitro oocyte maturation could be a promi...

Recent studies support the concept that NK cells play an important role in the success or failure of embryo implantation. Recurrent spontaneous abortion (RSA) is the most common complication of pregnancy. Some couples suffer from infertility of unknown cause. In vitro fertilization (IVF) is one of the useful treatment methods used for treatment of this type for infertility with variable outcome...

Embryo implantation depends on both embryo quality and the endometrial environment. Implantation failure has a complex, variable pathophysiology and is detrimental to the outcome of in vitro fertilization (IVF). Thus, patients with multiple implantation failure require an individualized approach to diagnosing and managing treatment options for future IVF cycles. These options should be based on...

In women undergoing in vitro fertilization (IVF) who have an implantation failure (IF) after repeated embryo transfer, an association with the presence of acquired thrombophilia has been demonstrated, and a thromboprophylaxis seems to be efficacious in improving implantation rate. More recently a role inherited trombophilia has been recognised to have a role in recurrent otherwhise unexplained ...

Background: Tuberculosis of the genital tract is one of the major causes of gynecological morbidity. Genital TB affects about 12% of patients with pulmonary tuberculosis and represents 15-20% of extrapulmonary tuberculosis.

BACKGROUND Sulfatase 1 (SULF1) function is to remove the 6-O-sulphate group from heparan sulfate. This action changes the binding sites of extracellular growth factors. SULF1 expression has been reported to be changed in angiogenesis. We hypothesized that single nucleotide polymorphisms (SNPs) of SULF1 would impact clinicopathologic characteristics. OBJECTIVE Study of SULF1 gene polymorphism ...
