The primary objective of this study is to investigate whether bicalutamide given in combination with anastrozole once daily for 12 months is effective in treating testotoxicosis in boys. Testotoxicosis is a condition that causes early puberty in boys including growth in height, and development of muscles and sexual organs.

OBJECTIVES: Purify and characterize a testis-stimulating factor in the blood of adult volunteers who had precocious puberty as boys.
The purpose of this study is to determine if leuprolide acetate is safe and effective in treating children with Central Precocious Puberty, and to assess long term effects of leuprolide ac...
The purpose of this study is to determine if leuprolide acetate (11.25 mg and 30 mg) is safe in treating children with Central Precocious Puberty over a longer period of time (12 months).
The purpose of this study is to determine if new formulations (11.25 and 30 mg) of leuprolide are effective in treating children with Central Precocious Puberty.
The purpose of this study is to evaluate the safety, effectiveness and pharmacokinetics of a study drug called Faslodex (fulvestrant) in the treatment of progressive precocious puberty (ea...
To study expressions of netrin-1 and its receptor UNC5C in female precocious puberty rat hypothalamus, and explore its effect on precocious puberty process.
Considering the role of kisspeptin (KISS) in the process of puberty, this study aimed to determine the mutation of KISS1 gene among a group of patients with idiopathic central precocious puberty (ICPP...
Central precocious puberty (CPP) may have clinical implications in adulthood.
It is important to differentiate central from peripheral causes of precocious puberty because of distinct management options.
The histrelin implant has proven to be an effective method of delivering gonadotropin-releasing hormone analog (GnRHa) therapy to children with central precocious puberty (CPP), yet there are limited ...
Development of SEXUAL MATURATION in boys and girls at a chronological age that is 2.5 standard deviations below the mean age at onset of PUBERTY in the population. This early maturation of the hypothalamic-pituitary-gonadal axis results in sexual precocity, elevated serum levels of GONADOTROPINS and GONADAL STEROID HORMONES such as ESTRADIOL and TESTOSTERONE.
A potent synthetic agonist of GONADOTROPIN-RELEASING HORMONE with 3-(2-naphthyl)-D-alanine substitution at residue 6. Nafarelin has been used in the treatments of central PRECOCIOUS PUBERTY and ENDOMETRIOSIS.
The lack of development of SEXUAL MATURATION in boys and girls at a chronological age that is 2.5 standard deviations above the mean age at onset of PUBERTY in a population. Delayed puberty can be classified by defects in the hypothalamic LHRH pulse generator, the PITUITARY GLAND, or the GONADS. These patients will undergo spontaneous but delayed puberty whereas patients with SEXUAL INFANTILISM will not.
A neoplasm composed entirely of GRANULOSA CELLS, occurring mostly in the OVARY. In the adult form, it may contain some THECA CELLS. This tumor often produces ESTRADIOL and INHIBIN. The excess estrogen exposure can lead to other malignancies in women and PRECOCIOUS PUBERTY in girls. In rare cases, granulosa cell tumors have been identified in the TESTES.
Benign and malignant tumors of the HYPOTHALAMUS. Pilocytic astrocytomas and hamartomas are relatively frequent histologic types. Neoplasms of the hypothalamus frequently originate from adjacent structures, including the OPTIC CHIASM, optic nerve (see OPTIC NERVE NEOPLASMS), and pituitary gland (see PITUITARY NEOPLASMS). Relatively frequent clinical manifestations include visual loss, developmental delay, macrocephaly, and precocious puberty.
