[Development of the rudimentary prostates of Ellobius lutescens (Microtinae) in organ culture; effects of androgens (author's transl)].

The structure of the rudimentary prostates of Ellobius lutescens is maintained intact after 6 days of organotypic culture in the absence of male hormones. Comparison with controls even shows a noticeable increase in the size of the epithelial cells. Adding male hormones to the culture medium does not modify the morphology of adult prostates, while it induces a sharp stimulation of immature prostates. In accordance with our previous results, these experiments show that the prostates of Ellobius lutescens lose their sensivity to androgens after puberty.
