Lymphocyte immune therapy is used in women with recurrent spontaneous abortions. This immunization is made from the father-to-be's blood or sometimes from a donor's blood. It is injected under the skin of the mother's forearm. This is done twice, separated by one month. Testing to see that it has worked is done one month after the second treatment. Common reactions to this treatment include: swelling, irritation, and itching at the injection site. Some women run a fever after this treatment.
