title: [Ultrastructural findings in testicular feminization].
abstract: On the basis of light and electron microscopic findings problems of the morphology of gonads in testicular feminization syndrome (TF) are discussed. Within the tubules 3 cell types (light, dark, intermediate) can be distinguished which are regarded as different functional forms of Sertoli cells. Germ cells were not observed definitely. There are, however, remarkable difficulties in morphological distinction between undifferentiated Sertoli and germ cells. It is underlined that fine structure of gonads and cellular composition of tubules as well as the amount of interstitial cells depend on the age of the individuum and on the form of TF (complete and incomplete).
