Abstract:
Little is known about the reproductive endocrinology of the male fruit bat Rousettus leschenaulti except that adult males show double peaks in their testicular activity corresponding to the two pregnancy cycles of the female.First peak occurs during February – March and second occurs during October-November. The levels of Follicle stimulating hormone (FSH) and Testosterone (T) were measured in sera of 36 male fruit bats over a period of 12 months. Result showed that concentration of FSH and T were increased significantly (P < 0.05) during October-November, February and March as compared to other months of the year. These results indicate that the changes due to breeding season affects the activity of the hypothalamic – testicular axis leading to a decrease or increase these hormones.
Keywords: fruit bat, testosterone, follicles stimulating hormone.
