Abstract: The interstitial cells of the toad Bufo Bufo gredosicola were studied throughout the seasonal period of spermatogenesis (from April to October) by means of immunocytochemical detection of testosterone and quantitative histological studies. The total number of interstitial cells per testis did not vary during the spermatogenetic period. However, in April, May and October, there were many interstitial cells showing an abundant testosterone content, whereas from June to September poorly-differentiated interstitial cells with a scanty testosterone content are the most abundant interstitial cell type. Since the interstitial cells with abundant testosterone content are larger than the interstitial cells with scanty testosterone content, the volume occupied by interstitial cells decreased in June-September. The development of thumb pads coincides with that of testosterone containing interstitial cells.
