Lymphatic immunotherapy can help embryo implantation and reduce the risk of embryo miscarriage. 1. Helping embryo implantation: Lymphatic immunotherapy is mainly a technique of injecting lymphocytes isolated from male blood into female body, which helps regulate the immune status of female after treatment, especially for women with abnormal endometrial immune cells, which has a better therapeutic effect. Therefore, the treatment can help embryo implantation to a certain extent. 2. Reduce embryo miscarriage: after lymphatic immunotherapy, it can prevent the antigens from the father in the embryo from being recognized or killed by the antigens from the mother, thus it can prevent the trophoblast cells of the embryo from being attacked and block the harmful immune response. This helps to maintain a normal pregnancy, reduce the rate of embryonic miscarriage, and protect the growth and development of the embryo. Although lymphatic immunotherapy has some benefits for the embryo, the mechanism of lymphatic immunotherapy is not clear according to current research. A hospital visit is required prior to undergoing lymphatic immunotherapy to assess the situation and then proceed under the guidance of a doctor.
