title: [Testis and ovary in a didactic histological and terminological comparison].
abstract: The so-called sex glands are not glands but germ hives. The germ cells are surrounded by nurse cells which alone build the tubulus or follicle epithelium (spermio- and oonutricytes). In the testis there is being differentiated between intra- and extratubular blood-germ cell barriers. The sperm cells should ultimately be called spermiocytes, the egg cells no longer be confused with the egg. The 4 germ cell generations and their 4 developmental phases in both organs are compared point by point. The interstitial cells are named andro- and gynocytes for considered reasons. The search for suitable names promotes knowledge and teaching.
