Schistosomiasis of the prostate and the seminal vesicles: observations in Zambia.

The pattern of schistosomiasis of the prostate and seminal vesicles in Zambia is presented. The results were based on histological examination and digestion of tissue obtained from 50 cadavers. Compared to the bladder (62%) and seminal vesicles (58%), the infestation was least common (50%) in the prostate. The infection was due to Schistosoma haematobium alone in all organs. The most significant finding was the histological inactivity secondary to this parasitic infection. It is suggested that schistosomiasis of these organs is unlikely to be causally related to male infertility in Zambia.
