Abstract
The activity of Mg2+-activated ATPase was studied in the rat testis employing histochemical and microphotometrical methods. The enzymatic activity could be correlated with the stages of spermatogenesis. From stage XII onwards, the elongated spermatids showed a weak to moderate activity, which increased from the acrosomal phase to the, maturation phase. The reaction product was located in the mid-piece and tail piece of elongated spermatids with a maximum intensity at stage VIII. Morphometric analysis revealed six distinct patterns, which could be correlated with the stages of spermatogenesis.
