Five men (aged 29-43 years) with ejaculatory dysfunction and spinal cord injuries for 10-41 years and level of complete lesions from C6 to T10 underwent electrostimulation. Antegrade ejaculate was obtained in all five participants and simultaneous retrograde ejaculation in four. In general, the total number of spermatozoa was greatest in the retrograde ejaculates and highly variable between the subjects both in the antegrade (0.2-5330 mill.) and in the retrograde ejaculates (0.4-5690 mill.). The percentage of immobile and morphologically abnormal spermatozoa was increased compared with normal values. In connection with the electrostimulation procedures no cases of autonomous hyperreflexia or rectal mucosal injury were observed.
