SOME OBSERVATIONS ON THE HISTOLOGY AND HISTOCHEMISTRY OF THE SEMINAL VESICLES OF THE BULL

Abstract

SUMMARY 1. The account of the cells of the seminal vesicles of the mature bull given by Mann et al. [1949] has been confirmed. 2. Evidence is presented that cells of the inner layer of the alveolus undergo cyclic changes. These cells, at one stage of the cycle, contain much glycogen and are probably responsible for the secretion of fructose. 3. Fat, in large part phospholipid, is mainly confined to the cells of the outer layer of the alveolus. 4. Comparable cells in the calf and bullock contain no glycogen and virtually no fat, confirming that the secretion of these substances is dependent upon the presence of androgenic hormone.
