Premature menarche--a legend or a defined clinical syndrome.

The properness of diagnosing the premature menarche as isolated clinical syndrome is often questioned. A long-term observation od 2 girls with premature menarche has been described. A discussion is presented about the role of imbalance within the hypothalamus-pituitary-gonads axis and the role of disturbances in peripheral responsiveness to sex hormones in the patho-mechanism of premature menarche.
