Official Title: Follicle-Stimulating Hormone (FSH) and the Onset of Puberty
Brief Summary:
The purpose of this study is to determine if the timing of the onset of puberty may be affected by FSH-regulatory peptides.
We will determine how these peptides relate to FSH production in prepubertal and pubertal children by comparing the regulation of FSH control in children with precocious (early) puberty and delayed puberty.
In this pilot study, we will stimulate the pubertal axis using an agonist of GnRH to determine the pubertal response of activin-A, inhibin-A and -B and follistatin.
To determine baseline FSH secretion and FSH-regulatory peptide tone, we will block GnRH with a specific antagonist.
These studies should lead to a better understanding of the role of FSH in controlling the onset of puberty and the pathogenesis of pubertal disorders.
