Description :
The seasonal pattern of body weight and testes weight of male bats were recorded and correlate with circulating serum testosterone in the wild caught bat, Taphozous kachhensis (Dobson). A gradual increase in the body weight as well as testes weight were recorded from the month of October which was the recrudescence period of the testicular cycle (preparation of testes for spermatogenesis) where as marked decline was apparent from April till July (the phase of regression). The body weight and testes weight reached a peak level in December which is the breeding phase when vigorous spermatogenesis occurs followed by mating in late November. The peak of testosterone coincided with the peak of the body weight and testes weight. A highly significant correlation was noted between body weight –testosterone (r= 0.61, p<0.001), testes weight-testosterone (r= 0.72, p<0.001) and even between body weight-testes weight (r=0.79, p< 0.001). Thus peak level of testosterone and testicular activity concludes the existence of close correlation with the reproductive activity which leads to the successful annual breeding cycle of the present bat.
