Evaluation of the functional state of male accessory glands by the analysis of seminal plasma.

In man, the seminal vesicles, together with the ampuls, constitutes the main source of seminal fructose. The human prostate produce citric acids, acid phosphatase and other enzymes. The exceeding high content of prostaglandins probably derives from the seminal vesicles. A combined analysis of fructose and citric acid in the ejaculate is desirable to state morphologic alterations or functional disturbances of the accessory glands. The well-known split ejaculate method enables to decide whether the ejaculatory process is normal, slight or heavily disturbed. Variations in the morphology and secretory function of the accessory glands in different mammalian species are pointed out. The influence of testosterone on the secretory function of the accessory glands is described and discussed in detail.
