Effects of prolactin on luteinizing hormone-stimulated testosterone secretion in isolated perfused rat testis
prolactin testes luteinizing hormone testosterone secretion
2009/2/23
The direct peripheral effect of prolactin on LH-stimulated testosterone secretion was re-evaluated using the intact, isolated, perfused rat testis. In paired experiments, one testis was infused wi...
Intratesticular factors and testosterone secretion. Effect of treatments that alter the level of testosterone within the testis
Intratesticular factors testosterone secretion testosterone testis
2009/2/23
The authors recently have reported the presence of a nongonadotropic polypeptide factor in rat testicular interstitial fluid that can exert marked stimulatory effects on Leydig cell testosterone pro...
Evidence that estrogen regulation of testosterone secretion in adult rams is mediated by both indirect（gonadotropin dependent）and direct（gonadotropin independent）means
estrogen regulation testosterone secretion adult rams
2009/2/23
Involvement of endogenous estrogen in the regulation of gonadotropin and testosterone secretion was investigated in adult rams. Groups of four rams were either passively immunized against estradio...
Relationship between rapid eye movement sleep and testosterone secretion in normal men
Luteinizing hormone follicle-stimulating hormone
2009/2/18
The relation between the pituitary-gonadal hormones' rhythm and sleep physiology in men is not fully elucidated. To examine whether the reproductive hormones are correlated with sleep architecture, ...
Effects of follicular fluid administration on serum bioactive and immunoreactive FSH concentrations and compensatory testosterone secretion in hemicastrated adult rats
Rat hemicastration follicle-stimulating hormone(FSH) testosterone inhibin
2009/2/7
In adult rats, removal of one testis (hemicastration) results in an elevation of serum follicle-stimulating hormone (FSH) concentrations and a compensation in testosterone secretion by the remain...
Tumor necrosis factor and interleukin-1 stimulate testosterone secretion in adult male rat Leydig cells in vitro
umor necrosis factor interleukin-1 testis testosterone
2009/2/6
The actions of two cytokines, tumor necrosis factor (TNF) and interleukin-1 (IL-1), on testosterone production by dispersed adult testis cells and purified Leydig cells in culture were studied. In o...
