Morphology of the prolactin producing cells in androgen-sterilized female rats.
The aim of the study was to follow morphology of the prolactin producing cells in growing female rats with evoked "early androgen syndrome". The experiment was carried out on 3, 6 and 12-week-old animals. At the age of 3 weeks no changes in morphology of the prolactin cells were observed as compared to that of control animals. In 6 and 12-week-old animals the significant differences between androgenized and control animals were found. The prolactin cells differed both from those characteristic for normal females and normal males. The main characteristic features were: significantly smaller number of cells than in normal females, their stronger fluorescence and presence of large and giant prolactin cells similar to the so called "pregnancy cells". Possible factors responsible for the described above changes are discussed.
