Functional disturbance of rat sexual accessory glands in an early phase of lead intoxication.
In order to investigate the effects of chronic lead intoxication on sexual accessory glands adult male Wistar rats were poisoned by ad libitum ingestion of lead acetate at concentrations of 0.5 g/l and 1.0 g/l for 90 d. Blood lead exhibited a significant increase in both treated groups. A decrease in hematocrit and hemoglobin, besides a rise in glycemic levels, confirmed lead intoxication. No sign of lesion was detected upon histologic examination of prostate, seminal vesicle, and coagulating gland. A morphometric technique revealed that, in this early phase of intoxication, no alteration occurred in the prostate's and seminal vesicle's epithelial height. However, a significant decrease in fructose content was observed in both lead treated groups. The results, revealing a precocious envolvement of male sexual accessory glands in lead intoxication, were related to disturbance in plasma testosterone level and also probably in androgen receptors.
