Official Title: A Preliminary Study About Recurrent Spontaneous Abortion and Repeated Implantation Failure IVF-ET Patients Treated by Active Immunotherapy With Small Amount of Lymphocytes

Brief Summary: Recurrent spontaneous abortion(RSA) and repeated implantation failure (RIF) during IVF-ET severely affects IVF live birth rate and patient's health.The specific etiology contains chromosomal abnormalities, reproductive anatomical abnormalities, endocrine disorders, reproductive system infections, autoimmune and environmental factors. However there are still 50% to 60% RSA which don't have a clear cause, called unexplained recurrent spontaneous abortion (URSA), mainly related to immune factors.Among various treatments,lymphocytes active immunotherapy is the most common treatment method, and its clinical efficacy is widely recognized although its action mechanism is not clear so far.
