AMH and spindle cell hemangioma: suggested that while TPOAb positivity was not associated with ovarian reserve, SCH was associated with a lower AMH concentration (mean difference = -0.27 ng/mL [CI -0.43 to -0.12 ng/mL], P = 0.001), and lower AFC (mean difference = -0.7 [CI -1.3 to -0.2], P = 0.005) (32).
