| dc.description.abstract | One of the most important reasons of infertility and human reproductive failure is related to uncontrolled immunological response of maternal immune system to early embryo or fetus, that cause rejection of this semi-allograft. Therefore, a tolerance in the immune system is essential to modulate the reactions against the fetus to avoid rejection. The immune system imbalance during implantation or pregnancy may lead to implantation failure or miscarriage. So, use of immunosuppressive or immunomodulator agents can be helpful to prevent immunological attack. Initially, there was a focus on steroids like prednisolone or intralipids in treatment of miscarriage that suppressed the activity of most immune cells, Intravenous Immunoglobulin (IVIG) was then introduced with various mechanisms. Nowadays, novel and specific strategies are established such as monoclonal antibodies and cytokines. More recently, Tacrolimus and Cyclosporine, which were utilized in prevention of transplantation reject, are used as immunosuppressive factors in modulation of immune responses against the fetus. This review is focused on the main immunotherapeutic methods of infertility treatment. | |
