Luteinizing hormone secretion by male rat pituitary cells perifused in vitro：effect of experimental left varicocele and orchiectomy
Luteinizing hormone secretion male rat pituitary cells
2009/2/23
It has been shown previously that experimental left varicocele in the rat, results in a bilateral decrease in intratesticular testosterone. In the present work, pituitary responsiveness to GnRH as a...
Pituitary response to LHRH during chronic renal insufficiency in the male rat
Pituitary LHRH chronic renal insufficiency male rat
2009/2/23
Chronic renal insufficiency was induced in young adult male rats by a 2-step 5/6 nephrectomy. Four weeks after surgery the rats were anesthetized with ketamine and injected with saline or 1, 5, 10...
Pituitary gonadotropin content in gonadectomized rats. Immunoassay measurements influenced by extraction solvent and testosterone replacement
Pituitary gonadotropin content gonadectomized rats Immunoassay measurements extraction solvent
2009/2/23
Increasing interest in events regulating gonadotropin synthesis and secretion led to the reexamination, by radioimmunoassay (RIA), of the pituitary content of luteinizing hormone (LH) and follicle s...
Pituitary-testicular reserve in men with low serum testosterone and normal serum luteinizing hormone
Pituitary-testicular reserve men with low serum testosterone normal serum luteinizing hormone
2009/2/23
Men with low serum testosterone levels who do not have elevated serum LH levels are generally thought to have hypothalamic-pituitary dysfunction. To evaluate this concept, seven men with a combinati...

pituitary-testicular axis moderate exercise males diabetes mellitus normal sexual function
2009/2/23
Hormonal studies of pituitary-testicular function in insulin-dependent diabetes mellitus were examined at rest and during moderate exercise to assess whether diabetes per se caused abnormalities of ...

Pituitary-testicular function prostatic cancer patients gonadotropin-releasing hormone
2009/2/23
Endogenous testosterone (T), LH and FSH receptors, and in vitro production of cyclic adenosine-3':5'-monophosphate (cAMP), T and some of its steroid precursors were measured in testicular tissue obt...
Pituitary-testicular function of prostatic cancer patients during treatment with a gonadotropin-releasing hormone agonist analog. I. Circulating hormone levels
Pituitary-testicular function prostatic cancer patients treatment gonadotropin-releasing hormone
2009/2/23
Eight patients with advanced prostatic carcinoma (ages 59 to 78 years) were treated with a potent gonadotropin-releasing hormone (GnRH) agonist analog (buserelin, Hoechst; 600 micrograms intranasall...
Pituitary-gonadal function in adult male rats subjected to chronic water restriction
water restriction protein-calorie deficit circadian rhythms FSH LH testosterone acute stress
2009/2/23
The effect of water restriction on the pituitary-gonadal axis has been studied in adult male rats. Water restriction did not modify FSH, LH and testosterone levels. However, both LH and testosterone...
Increased plasma and pituitary prolactin concentrations in adult male rats with selective elevation of FSH levels may be explained by reduced testosterone and increased estradiol production
Increased plasma pituitary prolactin concentrations adult male rats
2009/2/23
The roles of testosterone and estradiol in regulating prolactin concentrations were studied in acutely castrated adult male rats receiving subcutaneous Silastic implants of the sex steroids. Testost...
The effect of exogenous follicle stimulating hormone treatment on anterior pituitary and testicular function in the prepubertal bull
follicle stimulating hormone luteinizing hormone testosterone prepubertal bull
2009/2/20
The effect of exogenous follicle stimulating hormone (FSH) on testicular function was studied in twenty 4-month-old Holstein bulls during two seasons (ten in late winter and ten in summer). Five mg ...
