    Article Title: Serum leptin levels in males with delayed puberty during short-term pulsatile GnRH administration
    Article Snippet: Leptin may be a possible trigger for puberty.. In normal males, it has been shown that leptin increases from the pre-pubertal to the early pubertal stage, and then declines in the late pubertal stage.. We examined leptin levels in six male adolescents (mean age 16.3±0.6 yr; range 14.217.6 yr) with delayed puberty (constitutional delay of puberty no.=2; idiopathic hypogonadotropic hypogonadism no.=4) during 120 days of subcutaneous pulsatile GnRH administration.

Serum leptin levels were determined in duplicate with immunoradiometric assays (Human Leptin RIA kit, DRG Instruments GmbH, Marburg, Germany), with a sensitivity of 0.5 ng/mL, an intra-assay coefficient of variation of 3.4–8.3%, and an inter-assay coefficient of variation of 3.0–6.2%. .. The statistical analysis of data was performed with the Statistical Package for Social Science 29.0 (SPSS Inc., Chicago, IL, USA).
