Schistosomiasis: an unusual cause of tubal infertility.

A case report of a Nigerian woman having an unusual cause of tubal infertility is presented. On histological examination of the Fallopian tube, ova of Schistosoma haematobium enclosing living miracidia were found in the smooth muscle layer of the Fallopian tube and its mesosalpinx. Mechanisms of tubal involvement are analysed. The case indicates the need to consider schistosomiasis as a possible aetiological factor in patients with tubal infertility coming from areas where the disease is endemic.
