What is Lymphocyte Vaccine Therapy?
Lymphocyte Immunotherapy (LIT) is a supportive immunotherapy treatment applied particularly to couples experiencing recurrent miscarriages or unexplained infertility problems. In some cases of infertility, the problem is not due to the quality of the egg or sperm, but rather the immune system’s perception of the embryo as “foreign.” In this case, the mother’s body develops a defense mechanism against the tissues that make up the baby, which can result in miscarriage.
The aim of lymphocyte vaccination therapy is to regulate this immune response, thereby ensuring the embryo implants successfully in the uterus.
This method, which has been safely applied since 1978, is now frequently used in in-vitro fertilization (IVF) treatments to increase pregnancy success.

How is Lymphocyte Vaccine Therapy Administered?
Lymphocyte transfusion therapy (LIT) is a completely safe, specialized procedure prepared in a laboratory setting.
The treatment process proceeds as follows:
- A blood sample is taken from the prospective father.
- This sample is separated using special solutions and centrifugation.
- Lymphocyte cells are isolated and prepared sterilely.
- The harvested cells are injected in small doses under the skin in four different areas of the expectant mother’s arm.
💉 You may experience a slight burning sensation during the procedure, but it is not painful.
This injection is usually administered in 2-3 sessions before embryo transfer and 1-2 sessions after the transfer.
