What is LIT?

Lymphocyte Immunization Therapy or LIT is a procedure where white blood cells from the prospective father are injected into the skin of the prospective mother to prepare the maternal immune system for pregnancy. Because pregnancy tissues are the product of both the mother's as well as the father's genes, LIT assists the mother's immune system in the development of immunologic tolerance to the genetically foreign pregnancy tissues.
