Conclusions
-
1.
A single administration of luliberin to intact animais in a dose of 100 μg leads to a pronounced transitory rise in the LH and testosterone levels in the peripheral blood plasma.
-
2.
Administration of luliberin 30 min before stress stimulates the secretion of LH by the pituitary, but does not prevent the stress-induced decrease in the testosterone level in the blood.
-
3.
A single administration of 4500 units of hCG leads, in intact animals, to a sharp rise in the testosterone concentration, which remains at a high level for three days after stimulation of the gonads.
-
4.
Preliminary stimulation of the testes by hCG prevents the stress-induced suppression of the testosterone level in the blood plasma; however, the reaction of the testes to the stimulating effect of hCG is decreased in this case.
