The role of Mycoplasma in human infertility.

Seminal fluid from males complaining of infertility was examined for the presence of T-mycoplasmas and Mycoplasma hominis. No significant difference, with regard to the presence of mycoplasmas, was found between the seminal fluid which had normal cytology and seminal fluid of which the cytology was deemed pathological. Colonisation was shown to be an evanescent phenomenon, and female consorts often had different mycoplasma flora to the males. No positive role of mycoplasmas in the pathogenesis of infertility could be shown.
