Antiphospholipid Antibodies and Fertility: No Impact on Ovarian Reserve in Premenopausal Women

Abstract

Objective: To investigate possible differences in levels of ovarian reserve between antiphospholipid antibodies (aPL) asymptomatic carriers and antiphospholipid syndrome (APS) patients, by measuring the levels of anti-Müllerian hormone (AMH). Methods: We enrolled 69 premenopausal women divided in 2 groups: a) patients with APS, either primary (PAPS) or secondary (SAPS), according to the Sydney classification criteria; b) asymptomatic aPL carriers. Aged-matched premenopausal healthy donors (HDs) were also recruited. Complete aPL testing was performed and AMH levels were measured using enzyme-linked immunosorbent assay. Results: Among the 69 patients included in the study, 22 were diagnosed with PAPS, 13 with SAPS, and 14 patients were asymptomatic aPL carriers. No differences in AMH levels were observed among the three groups [mean AMH: PAPS 3.09 ng/ml ± 1.9 (range 1.02 − 7.1); SAPS 3.1 ng/ml ± 2.2 (range 1.1 − 7.6); aPL carriers 2.2 ng/ml ± 5.4 (range 1 − 6.3)] and between patients/aPL carriers and HDs [mean AMH 2.82 ng/ml ± 2.9 (range 1 − 6.9)]. Any correlation between the global APS score (GAPSS) and AMH levels failed to be found (rho = 0.31; p = 0.073). Conclusion: With the limitations of the current study, as observed in women with APS, we confirm that ovarian reserve, assessed with AMH levels, is not reduced in premenopausal women with isolated aPL positivity. Moreover, when granulating the aPL profile in terms of risk assessment, using the GAPSS, no impact on fertility was observed.
