BACKGROUND: The possible difference of antimüllerian hormone (AMH) levels at central precocious puberty (CPP) and premature thelarche (PT) has not been properly evaluated. OBJECTIVE/HYPOTHESIS: By evaluating AMH levels in girls with diagnosed CPP and PT, we aim to show the change of AMH levels at the pubertal onset. SUBJECTS: Sixty-five girls who have breast development before the age of 8 years and 25 healthy girls were enrolled in the study. METHODS: The subjects were divided into two groups as CPP and PT, according to results of GnRH test. AMH levels were determined in the two groups. RESULTS: The mean AMH levels of the CPP group were significantly lower than those in the PT group (13.57±9.85 pmol/L and 58.42±12.78 pmol/L, respectively, p=0.022). CONCLUSION: These results suggest that the AMH levels decrease in the duration of the hypothalamus-pituitary-ovarian axis activation. We thought that AMH might/may be a marker for distinguishing between CPP and PT.
