The effect of 3 months exposure to short day length (L:D, 9:15) on spermatogenesis in R. cyanophlyctis was studied. There was no difference in the qualitative and quantitative aspect of spermatogenesis between control frogs exposed to ambient photoperiod (L:D, 12.16:11.44) and frogs exposed to short day light. The present findings indicate that light has no role in spermatogenesis in the frog.
