Cyclosporine is an immunosuppressant. When a woman has infertility or repeated miscarriage, some factors may be due to autoimmune abnormalities in the body, which may lead to repeated failure of implantation. These drugs are first-line immunosuppressants and have a certain effect on successful embryo implantation. Cyclosporine does not belong to the first-line immunosuppressive drugs. If the above drugs are not effective, cyclosporine can be considered as a second-line immunosuppressive drug, which may have some effect on embryo implantation.
