Glycogen content in the rat testis was chemically and histochemically studied during maturation of the gonad. Higher values in the immediate post-natal period, and an abrupt drop in 10- and 15-day-old rats was observed. From 20 days onward, there was a progressive decrease, reaching the lowest values in adultanimals. Histochemically, glycogen was mainly present in the germinal cells, i.e., in gonocytes from 5 to 15 days old, and in primary spermatocytes from 15 to 20 days. A weaker reaction was noticed in spermatogonia and Sertoli cells of adult animals. (Endocrinology85: 607, 1969)
