Anti-Mullerian hormone levels in American girls by age and race/ethnicity.

Background: Anti-Mullerian Hormone (AMH), a proposed indicator of ovarian follicle reserve in adults, has not been characterized in pediatric and adolescent females by race and/or ethnicity. Objectives: To describe AMH levels in healthy American girls and determine the influence of age and race/ethnicity on AMH. Subjects: Subjects aged 10-21 years were recruited from primary care settings and emergency departments. Race/ethnicity was characterized as White, Black or Hispanic. Methods: Serum for AMH levels (ng/mL) was measured using an enzyme-linked immunosorbent assay. Results: Thirty-one White, 60 Black and 24 Hispanic subjects were recruited. Mean AMH levels were 3.19 ng/mL (22.8 pmol/L) (SD 2.12) for Whites, 3.25 ng/mL (23.2 pmol/L) (SD 2.23) for Blacks and 2.97 ng/mL (21.2 pmol/L) (SD 1.75) for Hispanics. ANCOVA showed no difference in AMH levels among race/ethnicities, controlling for age (p=0.91). Age was significantly associated with AMH (p<0.001, R²=0.12). Conclusion: AMH levels do not vary by race/ethnicity, and AMH levels increase with age. [ABSTRACT FROM AUTHOR]
