Summary

This is an observational, retrospective, single-center study focused on the diagnosis of Central Precocious Puberty in female patients.

Detailed description

The study enrolls female patients undergoing GnRh testing for suspected diagnosis of Central Early Puberty between january 2017 and December 2020 at the Pediatrics Unit of IRCCS Azienda Ospedaliero-Universitaria di Bologna Policlinico di Sant'Orsola. The study design provides 2 cohorts of female patients on the basis of the LH peak value in GnRH test: patients with LH peak value \< 5U/L, and patients with LH peak value \> 5U/L. The primary aim is to assess the diagnostic power of basal LH comparing with the LH peak value after stimulus test with GnRH in female patients with suspected precocious puberty. The secondary aim is to assess the association of the following variables between the two cohorts: uterine volume, longitudinal uterine diameter, presence of endometrial rhyme, ratio of peak LH/FSH values and dose per kg of GnRH administered during stimulus test.
