The current guidelines do not allow pregnancy with Cellcept as its effects on the fetus are not known. Cellcept does not cause infertility. Successful pregnancies have taken place in large numbers in patients with successful kidney transplants or cyclosporin/Tacrolimus, azathioprine and prednisolone. Pregnancy is not recommended with MMF (Cellcept) and sirolimus though few successful pregnancies have occurred & reported with both drugs. I would also recommend you to stop Cellcept and switch to imuran as suggested by your nephrologist.
