Anti-mullerian hormone levels decline with the presence of antiphospholipid antibodies.

Problem: Autoimmunity is thought to be an important cause of premature ovarian senescence, characterized by abnormal ovarian reserve markers. Anti-Mullerian hormone (AMH) has emerged as the most reliable marker for ovarian reserve. We here investigated whether non-specific immune markers are associated with a low age-specific AMH.

Method Of Study: To test the hypothesis that autoimmunity may predispose to low AMH, we investigated in 351 female infertile patients whether panels positive for non-specific immune tests (antinuclear antibody, antiphospholipid antibodies [APAs], lupus anticoagulant, antithyroid antibodies, and total immunoglobulin levels) are associated with low AMH levels. Analysis of covariance was performed to determine statistical significance of associations.

Results: Age of infertile women was 38.6 ± 5.3 years. A total of 50 women (14.2%) had abnormally elevated levels of one or more APA. Even after age adjustments, the presence of at least one APA was significantly associated with a low AMH (P<.0066). No one specific APA or other immune marker demonstrated an association with AMH.

Conclusions: APAs but no other immune markers appear associated with decreased levels of AMH, supporting the hypothesis that non-specific autoimmunity may adversely affect ovarian reserve.
