The immune system fights infectious microorganisms and foreign particles when they produce antibodies. When the antibodies are made to fight against essential cells of the body itself, it is called Autoimmunity. Immunological infertility is caused by such an autoimmune response where the immune system attacks the sperms.
An autoimmune response causes the antibodies to treat the sperms as if they were foreign body particle. This can be due to an infection, trauma, vasectomy reversal or testicular cancer.
Treatment of immunological infertility depends on the particular person and the reason for the treatment. If the treatment is to have a baby, artificial reproductive technology like IUI,IVF and ICSI can be discussed.
