Microscopic examination of sperm as the diagnostic clue in a case of Schistosoma haematobium infection.

Early diagnosis and treatment of Schistosoma haematobium infections is imperative to prevent chronic manifestations of the disease. Microscopical examination of urine and faeces, and rectal biopsy are widely used standard methods for the rapid diagnosis of schistosomiasis. We report a case in whom numerous Schistosoma haematobium eggs were demonstrated in sperm, even though repeated examination of urine and rectal biopsies had been futile. It is concluded that the case presented demonstrates the importance of using sperm as an alternative sample material when schistosoma eggs are not found in conventional sample materials from male patients suspected of being infected with Schistosoma haematobium.
