Purpose: Gonadotropin-releasing hormone (GnRH) stimulation test is the gold standard for diagnosing central precocious puberty (CPP). However, intravenous GnRH is not always readily available. The purpose of this paper is to compare the results of gonadorelin and triptorelein used in the GnRH stimulation test in the diagnosis of CPP among girls.Methods: A retrospective clinical study (Intravenous Gonadorelin CPP VS Subcu...

A 9 - year-old boy was referred to our hospital because of precocious puberty. At the first visit, thyroid function test was performed using electrochemiluminescent immunoassay (ECLIA) and the serum TSH level was markedly elevated (32.30 μIU/mL), but the serum level of free T4 was within the reference interval. Anti-thyroid antibodies were negative and thyroid ultrasonography was normal. He diagnosed as central precocious puberty, but no clinical symptom of hypothyroidism. ...

Objective: In girls, breast development under 8 years of age and peak serum luteinizing hormone (LH) is 5 IU/L or higher in gonadotropin releasing hormone (GnRH) stimulation tests is a standard method for diagnosing CPP. Because of higher body mass index (BMI) was associated with a lower LH response in the GnRH stimulation test, BMI should be considered when interpreting the result of GnRH stimulation tests. We aimed to find out whether changes in BMI affect t...
