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-pituitaryovarian axis activation. We thought that AMH might/may be a marker for distinguishing between CPP and PT.enginfo:eu-repo/semantics/closedAccessAMHprecocious pubertypremature thelarchearticle2811-12135113560003650446000232-s2.0-849474451652191-0251
