Anti Ovarian Antibody test is done on a blood sample to estimate the level of Anti Ovarian Antibodies in the bloodstream. It's conducted to confirm female infertility as well as used during and after the infertility treatment. Antibodies are produced against the ovaries (autoimmunity) and this kind of antibodies bind to the vital functional sites of the ovaries and granulosa cells to obstruct the normal response. As per researches, anti-ovarian antibodies cause disturbances in normal ovulation process. They are also likely to be involved as a cause of non-responsive function to different medications (as well as techniques like IVF) for stimulating proper ovarian action. Patients with Premature Ovarian Failure and unexplained infertility have higher levels of such antibodies. Hence, these antibodies are believed to play role in female infertility.
