title: Effect of age on the activity of rat testicular arginine-aminopeptidase.
abstract: Effects of age on arginine-aminopeptidase activity were investigated in the rat testis. A marked rise of the enzyme activity in 6-week-old rats corresponded to the appearance of spermatids in the later stages of their development.
