Cytologic changes in the pars distalis of male buffalo following emasculation.

The effects of emasculation in the pars distalis of the pituitary gland were studied in male buffalo. Following castration, no size or percentage value changes could be noted in the acidophila and thyrotrophs of the pars distalis. The acidophils were found in greater numbers in the peripheral area of the pars distalis as compared to the central area. However, the frequency of thyrotroph distribution was observed to be more so in the central zone. As for the gonadotrophs, a significant increase in the cell size (P less than 0.05) and percentage value (P less than 0.01) was observed in animals castrated by the Burdizzo method. This points to a state of hyperplasia and hypertrophy of the gonadotrophs as a result of this method of emasculation.
