Testosterone concentration in testicular venous blood of adult rats and seminal citric acid and fructose concentration as well as weight of accessory sex organs.

In 31 adult rats of Wistar strain (body weight 231 +/- 14g) the relationships between testosterone concentration in testicular venous blood of an individual rat and weight of accessory sex organs (testes, seminal vesicles, ventral prostate, levator ani muscle) and citric acid and fructose concentrations in seminal vesicles were investigated. No direct relationship was found between testosterone concentration and the above parameters. The correlation coefficient varied from 0.042 to 0.394.
