Summary
Cytochemical and morphological evidence indicates the presence of glycogen packets in the condensed nuclei of Rana pipiens and Rana clamitans testicular spermatozoa. A possible reason for its existence is discussed. Glycogen is also demonstrated in the acrosomes of R. pipiens spermatozoa and in the middle pieces and tails of R. clamitans spermatozoa.
