PROTOCOL OUTLINE: All patients receive a gonadotropin-releasing hormone (GnRH) analogue. Treatment begins on days 1 to 3 of a menstrual cycle.
Low-dose estrogen begins at approximately 3 months. All patients must have a daily calcium intake of at least 1 gram; supplements are allowed.
Patients are followed for at least 1 year.
Primary Purpose: Prevention

RATIONALE: Androgens can cause the growth of prostate cancer cells. Luteinizing hormone-releasing hormone agonists may lessen the amount of androgens made by the body. Internal radiation u...
This study will evaluate the safety, pharmacokinetic (PK), pharmacodynamic (PD) activity, and preliminary anti-tumor activity of GDC-9545 as a single agent and in combination with palbocic...
This study was undertaken to evaluate bone response in metastatic prostate cancer patients treated with Enzalutamide with or without Zoledronic Acid in combination with luteinizing hormone...
The follicular phase of the menstrual cycle involves the hourly release of gonadotropin-releasing hormone, which binds to receptors on the gonadotropes. This results in the secretion of fo...
RATIONALE: Studying samples of blood and tissue from patients with prostate cancer after receiving implant radiation therapy and luteinizing hormone-releasing hormone agonist may help doct...
Different pharmacologic agents are used in the treatment of paraphilic disorders in sexual offenders or men with a risk of sexual offending, with luteinizing hormone-releasing hormone (LHRH) agonists ...
To explore the role of luteinizing hormone (LH) in the urinary continence mechanism, urethral function was investigated using a postmenopausal rat model with high serum LH concentrations and the postm...
The inhibitory effects of morphine and the stimulatory influence of kisspeptin signaling have been demonstrated on gonadotropin releasing hormone (GnRH)/luteinizing hormone (LH) release. Hypothalamic ...
The purpose of this study was to investigate a novel mutation in the luteinizing hormone beta-subunit (LHB) gene in one male patient with hypogonadism due to selective luteinizing hormone (LH) deficie...
Gonadotropin releasing hormone (GnRH) triggers secretion of luteinizing hormone and follicle stimulating hormone from gonadotropic cells in the anterior pituitary gland. GnRH is able to bind copper, a...
Receptors with a 6-kDa protein on the surfaces of cells that secrete LUTEINIZING HORMONE or FOLLICLE STIMULATING HORMONE, usually in the adenohypophysis. LUTEINIZING HORMONE-RELEASING HORMONE binds to these receptors, is endocytosed with the receptor and, in the cell, triggers the release of LUTEINIZING HORMONE or FOLLICLE STIMULATING HORMONE by the cell. These receptors are also found in rat gonads. INHIBINS prevent the binding of GnRH to its receptors.
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 potent synthetic long-acting agonist of GONADOTROPIN-RELEASING HORMONE that regulates the synthesis and release of pituitary gonadotropins, LUTEINIZING HORMONE and FOLLICLE STIMULATING HORMONE.
A major gonadotropin secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Luteinizing hormone regulates steroid production by the interstitial cells of the TESTIS and the OVARY. The preovulatory LUTEINIZING HORMONE surge in females induces OVULATION, and subsequent LUTEINIZATION of the follicle. LUTEINIZING HORMONE consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH and FSH), but the beta subunit is unique and confers its biological specificity.
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.
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...
