Abstract EN
The present study was conducted in the Laboratory of Animal Physiology and Biotechnology, Department of Animal Production, Faculty of Agriculture, Mansoura University, Egypt.
The present investigation aimed at studying effects of ages, pubertal stages and seasons of the year on testosterone concentrations in blood plasma and tissue homogenate of the testes.
The testes used in the current study were collected from a total of 104 one-humped male camels (Camelus dromedarius).
Samples were taken from pre (1–3.5 years) and post (3.5–13 years) pubertal camels.
Testes were studied for a two consecutive seasons.
The freshly prepared homogenate of the testicular tissue and blood plasma were used for determining the concentrations of testosterone in plasma and testicular extract.
The concentrations of testosterone in blood plasma and testicular tissue were significantly increased during the breeding season compared with that of non-breeding season; the concentration of testosterone was higher in testicular tissue than in blood plasma.
Testosterone concentrations in plasma and testicular tissue were increased in breeding than in non-breeding season.
In addition, the testosterone concentrations were closely related with seasonal changes, stage of puberty and advancing age.
