The Immune System’s Role in Fertility
The immune system protects the body from infections and 男性 不妊症 invaders. However, in some cases, it mistakenly identifies sperm as a threat and mounts an immune response, leading to infertility.
Mechanisms of Immune-Related Infertility:
- Anti-Sperm Antibodies (ASA):
- These antibodies attack sperm, reducing motility, impairing their ability to bind to and penetrate the egg, or causing clumping (agglutination).
- Inflammatory Responses:
- Chronic inflammation in the reproductive organs can damage sperm production and transport.
Causes of Immune Infertility:
- Trauma or surgery involving the testes, which may expose sperm to the immune system.
- Infections or inflammation in the male reproductive tract.
- Genetic predispositions to autoimmune disorders.
Diagnosis and Treatment:
- Testing:
- Special laboratory tests detect ASA in semen or blood.
- Treatment:
- Immunosuppressive drugs in some cases.
- Assisted reproductive technologies (ART) like intracytoplasmic sperm injection (ICSI) can bypass the effects of ASA by directly injecting sperm into the egg.
