Low-dose human chorionic gonadotropin maintains intratesticular testosterone in normal men with testosterone-induced gonadotropin suppression
(Endocrine Society, 2005-05)
In previous studies of testicular biopsy tissue from healthy men, intratesticular testosterone (ITT) has been shown to be much higher than serum testosterone (T), suggesting that high ITT is needed relative to serum T for normal spermatogenesis in men. However, the quantitative relationship between ...
Intratesticular testosterone concentrations comparable with serum levels are not sufficient to maintain normal sperm production in men receiving a hormonal contraceptive regimen
(American Society of Andrology, 2004-11)
Intratesticular testosterone (ITT) is thought to play a key role in the control of spermatogenesis in man but is rarely measured. The purposes of this study were 1) to examine the relationship between intratesticular fluid and serum testosterone (T) at baseline and during treatment with a contraceptive ...
Intramuscular testosterone enanthate plus very low dosage oral levonorgestrel suppresses spermatogenesis without causing weight gain in normal young men: a randomized clinical trial
(American Society of Andrology, 2005-05)
The development of a safe, well-tolerated, effective, and reversible male hormonal contraceptive would be a major clinical advance for couples planning their family size and for control of population growth. High-dosage parenteral testosterone (T) esters alone or in combination with a progestogen ...
Testosterone administration suppresses adiponectin levels in men
(American Society of Andrology, 2005-01)
Testosterone (T) administration to men increases lean body mass and decreases fat mass. Adiponectin is produced by adipocytes and is thought to influence insulin sensitivity. In this study, we sought to determine whether experimental alterations in serum T change adiponectin levels in normal men. ...
