Two experiments were conducted with adult intact rams (approximately 58 kg in body weight) in the nonbreeding season to investigate interrelationships between LH and testosterone secretion. In Exp...
The process of early testosterone (T) secretion and Leydig cell differentiation in humans was studied to explore the steroidogenic capacity of Leydig cell fibroblastic precursors. Seven cryptorchi...
The effect of testicular germ cell content on Leydig cell steroidogenic function in vivo in adult rats was examined. Three experimental paradigms were used to effect germ cell changes. First, a vita...
Previous studies have shown that the ability of Brown Norway rat Leydig cells to produce testosterone declines significantly with age. To address the possible mechanism(s) by which aging Leydig cell...
This study examines the effects of prenatal exposure to dexamethasone (DEX) on postnatal testosterone production in male rats. Pregnant female rats were treated on gestation days 14-19 with DEX (1...
The effects of melatonin on steroidogenesis and steroidogenic acute regulatory (StAR) protein expression were investigated in MA-10 mouse Leydig tumor cells. MA-10 cells were treated with human chorio...
Primary points of control in steroidogenesis are the transport of cholesterol from intracellular stores to the inner mitochondrial membrane, and the subsequent conversion of cholesterol to pregnenolon...
Previous studies have shown that the capacity of Leydig cells from aged (21-24-month-old) Brown Norway rats to produce testosterone is reduced from young (4-month-old) levels, and that this is cor...
