RATIONALE: The body's response to one injection of leuprolide may provide more information than the standard test for gonadotropin deficiency in determining whether the cause of gonadotropin deficiency is related to the hypothalamus or the pituitary gland.
PURPOSE: Randomized double-blinded clinical trial to study the effectiveness of leuprolide in determining the cause of gonadotropin deficiency.
PROTOCOL OUTLINE: This is a randomized, double blind study. Patients are randomized to receive leuprolide acetate or gonadotropin releasing hormone (GnRH) first, then cross over to receive the other test.
Patients receive one subcutaneous injection of leuprolide acetate or GnRH, then have blood samples drawn periodically. One month later, patients receive the other test.
Another cohort of patients are randomized to receive leuprolide acetate once daily on days 0, 4, and 8, or days 0, 5, and 10.
Patients are followed for up to 2 years.
Allocation: Randomized, Endpoint Classification: Efficacy Study, Masking: Double-Blind, Primary Purpose: Treatment

Men with Idiopathic Hypogonadotropic Hypogonadism (IHH) lack a hormone called gonadotropin releasing hormone (GnRH). This hormone is important for starting puberty, maintaining testosteron...
The purpose of the study is to examine how Kallmann syndrome (KS) and idiopathic hypogonadotropic hypogonadism (IHH) affect reproductive hormones. These disorders are caused by a defect in...
The purpose of this study is to explore the effects of synthetic gonadotropin-releasing hormone (GnRH) upon the pituitary and ovaries of women with infertility. Women diagnosed with GnRH ...
OBJECTIVES: Assess whether chronic administration of gonadotropin-releasing hormone analogues is safe and effective for the prevention of cyclic attacks of acute porphyria in women.
OBJECTIVES: I. Evaluate the clinical efficacy of leuprolide, a gonadotropin-releasing hormone agonist (GnRHa), in treating infants with vision-endangering or large, disfiguring hemangiom...
To compare the efficacies of gonadotropin-releasing hormone (GnRH) pulse subcutaneous infusion with combined human chorionic gonadotropin and human menopausal gonadotropin (HCG/HMG) intramuscular inje...
Early puberty (EP) is due to the activation of gonadotropin-releasing hormone (GnRH) pulse generator in lower ages; EP may be a potential cause for impairment of adult height, leading to short stature...
Electromyographic studies have shown that external anal sphincter activity is modified in response to distension in animals with spinal cord injury. Gonadotropin-releasing hormone and its agonist leup...
Besides local reactions, systemic hypersensitivity reactions such as urticaria, anaphylaxis, serum sickness and Henoch-Schönlein purpura (HSP) have been reported during gonadotropin-releasing hormone...
Correlation of anti-Mullerian hormone with humanchorionic gonadotropin test in the evaluation of testicular function of children with 46 XY male hypogonadism: Use of anti-Mullerian hormone as abiomarker.
It is challenging to evaluate reproductive potential during childhood. These challenges necessitate the use of invasive dynamic tests. Although the anti-Mullerian hormone (AMH) is a reliable biomarker...
A potent synthetic long-acting agonist of GONADOTROPIN-RELEASING HORMONE that regulates the synthesis and release of pituitary gonadotropins, LUTEINIZING HORMONE and FOLLICLE STIMULATING HORMONE.
Cell surface proteins that bind corticotropin-releasing hormone with high affinity and trigger intracellular changes which influence the behavior of cells. The corticotropin releasing-hormone receptors on anterior pituitary cells mediate the stimulation of corticotropin release by hypothalamic corticotropin releasing factor. The physiological consequence of activating corticotropin-releasing hormone receptors on central neurons is not well understood.
A decapeptide that stimulates the synthesis and secretion of both pituitary gonadotropins, LUTEINIZING HORMONE and FOLLICLE STIMULATING HORMONE. GnRH is produced by neurons in the septum PREOPTIC AREA of the HYPOTHALAMUS and released into the pituitary portal blood, leading to stimulation of GONADOTROPHS in the ANTERIOR PITUITARY GLAND.
A potent synthetic long-acting agonist of GONADOTROPIN-RELEASING HORMONE with D-tryptophan substitution at residue 6.
A potent synthetic agonist of GONADOTROPIN-RELEASING HORMONE with D-serine substitution at residue 6, glycine10 deletion, and other modifications.
Endocrine disorders are grouped into two categories: hormone imbalance - when a gland produces too much or too little of an endocrine hormone development of lesions (such as nodules or tumors) in the endocrine system, which may or may not affect...
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
