Immune System Testing in IVF Failure
Understanding Immunological Causes of Implantation Failure
The immune system plays an important role in pregnancy. In some cases, immune responses may interfere with embryo implantation and early pregnancy development. Immune testing helps doctors identify abnormal immune activity that may contribute to repeated IVF failure or recurrent miscarriage.
How the Immune System Affects IVF
The immune system normally protects the body from infections and harmful substances. During pregnancy, the immune system must adapt to allow the embryo to implant and grow. In some individuals, abnormal immune responses may treat the embryo as a foreign body, interfering with implantation or causing early pregnancy loss. Researchers continue to study the exact role of immune factors in fertility, but certain immune-related conditions may contribute to repeated IVF failure.
Immune Factors That May Affect IVF
Natural Killer (NK) Cells
Elevated NK cell activity may affect implantation in some patients.
Autoimmune Disorders
Conditions like lupus or antiphospholipid syndrome may affect pregnancy outcomes.
Inflammatory Immune Responses
Chronic inflammation inside the uterus may interfere with implantation.
Cytokine Imbalance
Certain immune signaling molecules may influence embryo implantation.
Immune Tests Sometimes Recommended
