Quantitative assessment of nocturnal penile tumescence and rigidity in normal men using a home monitor
Quantitative assessment nocturnal penile tumescence rigidity normal men
2009/2/23
Current methods now permit the measurement of nocturnal penile tumescence and rigidity (NPTR) in men with erectile dysfunction. But the relationship of rigidity to tumescence and the changes in rigidi...
Circadian variation in testosterone, sex hormone-binding globulin, and calculated non-sex hormone-binding globulin bound testosterone in healthy young and elderly men
Circadian variation testosterone sex hormone-binding globulin healthy young and elderly men
2009/2/23
The circadian pattern in levels of serum total testosterone (T) in men becomes blunted with normal aging. However, because T not bound to sex hormone-binding globulin (non-SHBG-T) is felt to be a be...
Effect of MK-906, a specific 5 alpha-reductase inhibitor, on serum androgens and androgen conjugates in normal men
MK-906 5 alpha-reductase inhibitor serum androgens androgen conjugates normal men
2009/2/23
To determine the hormonal effects of MK-906, an orally active 5 alpha-reductase inhibitor, on serum androgens and androgen conjugates, 12 healthy men were given 10, 20, 50, and 100 mg MK-906 2 weeks a...
Nature of alpha subunit secretion in men：circadian rhythms, pulsatile release and secretory profiles
alpha subunit secretion men circadian rhythms pulsatile release secretory profiles
2009/2/23
Alpha subunit complements LH as a marker of the activity of the hypothalamic GnRH pulse generator. To characterize episodes of alpha subunit release and to determine if a circadian pattern of alpha ...
Treatment of men with idiopathic oligozoospermic infertility using the aromatase inhibitor, testolactone. Results of a double-blinded, randomized, placebo-controlled trial with crossover
men idiopathic oligozoospermic infertility aromatase inhibitor testolactone
2009/2/23
The hypothesis that increased estradiol production may be the cause of impaired spermatogenesis in infertile men with idiopathic oligozoospermia was tested by administering the aromatase inhibitor...
Indomethacin and oxaprozin lower seminal prostaglandin levels but do not influence sperm motion characteristics and serum hormones of young healthy men in a placebo-controlled double-blind trial
seminal prostaglandin levels sperm motion characteristics serum hormones young healthy men
2009/2/23
To evaluate the influence of indomethacin and oxaprozin on reproductive function in healthy young men, 34 volunteers with normal semen parameters were recruited. In a randomized double-blind design,...
24-hour pulsatile and circadian patterns of cortisol secretion in alcoholic men
24-hour pulsatile circadian patterns cortisol secretion alcoholic men
2009/2/23
Pulsatile and circadian patterns of cortisol secretion during acute (3 to 16 days) and chronic (29 to 39 days) abstinence were examined in alcoholic men with no clinical or laboratory evidence of he...
Diagnostic value of sperm function tests and routine semen analyses in fertile and infertile men
Diagnostic value sperm function tests routine semen analyses fertile infertile men
2009/2/23
The results of routine semen analyses, the zona-free hamster oocyte penetration test, the hypoosmotic swelling test, and semen adenosine triphosphate levels were studied in 66 fertile and 130 infe...
Effects of chronic sulpiride-induced hyperprolactinemia on plasma testosterone and its responses to hCG in normal men
Effects of chronic sulpiride-induced hyperprolactinemia plasma testosterone hCG normal men
2009/2/23
To elucidate the effects of sulpiride-induced (300 mg daily) long-term (64 days) hyperprolactinemia on basal and hCG-stimulated plasma testosterone (T), hCG was given to five normal men five times...
