[Genital mycoplasma strains as a cause of male infertility].

Mycoplasma hominis, M. fermentans, M. orale, M. gallisepticum and Ureaplasma urealyticum are able to reduce the motility of spermatozoa. Electron microscopical investigation confirmed an affinity of these mycoplasmas to the structures of the cell-membranes of the spermatozoa. Simultaneously there could be observed extensive destructions in spermatozoa.
