Guanylate cyclase activity has been studied biochemically and cytochemically in guinea pig testis. The results of the biochemical assays indicate an equal distribution of this enzyme between the soluble and particulate fractions, which have a different sensitivity to adenosine triphosphate. The cytochemical results demonstrate that the reaction product of guanylate cyclase is detectable in the interstitial capillary endothelial cells and, in the seminiferous epithelium, mainly at the level of the adjacent surfaces of Sertoli and germ cells of the intermediate and adluminal compartments. Guanylate cyclase activity appears at the level of pachytene spermatocytes and persists throughout subsequent stages of development. The distribution in the seminiferous epithelium seems to indicate that guanylate cyclase is involved in the interrelationships between Sertoli and germ cells during gamete differentiation.
