Newborn rat testis was transplanted under the kidney capsule of adult castrated and uncastrated male rats to develop and characterize a model system for studies on Leydig cell development. Two weeks...
The pattern of LH release in the adult ram influences the testicular steroidogenic response to individual LH pulses and is regulated by testosterone negative feedback
LH release adult ram influences testicular steroidogenic individual LH pulses
2009/2/23
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...

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...
