Fructose and Citric Acid Assay in the Secretions of the Accessory Glands of Reproduction as Indicator Tests of Male Sex Hormone Activity

Abstract

It is a well-established fact that the weight, size, histological appearance and secretory functions of certain accessory organs of reproduction, such as the seminal vesicle and the prostate, are strictly dependent on, and closely regulated by, the internal secretion of the testes; furthermore, that the typical retrogressive changes which occur in the accessory glands after removal of testes can be counteracted by injections of the testicular hormone, thus serving as 'indicator tests' for the male sex hormone

Seminal Degeneration in the Ram and Its Relation to the Temperature of the Scrotum

“…The production of fructose and citric acid by the seminal vesicles of rabbits and bulls was shown to be abolished by castration and restored by administra¬ tion of testosterone (Mann & Parsons, 1947;Mann Davies & Humphrey, 1949). Lindner & Mann ( 1960) Glover (1955Glover ( , 1956 Glover (1956) and Clegg (1960) who reported an increase in weight, citric acid and fructose content of the accessory glands of rats 15 days after the operation to make them cryptor¬ chid.…”

Plasma FSH, LH and testosterone levels in the male rat during degeneration of the germinal epithelium caused by severe heat treatment or ligation of the vasa efferentia

“…Fructose concentrations in the coagulating glands of individual animals were determined (Mann, Davies & Humphrey, 1949). The weight and cytological appearance of the accessory sex organs and the fructose concentrations were used as biological indices of circulating androgens.…”

The Association of Zinc With Some Components of Boar Vesicular Secretion and Seminal Plasma

“…Seminal plasma, vesicular secretion and epididymal plasma Seminal Speck, Moulder & Evans (1946) as modified by Mann, Davies & Humphrey (1949). Ergothioneine was determined by the modification of Mann (1964) of the method of Hunter (1949).…”
