[Diseases of the masticatory system as possible causal factors in infertility]

In this study 36 subfertile patients between 25 and 43 years, in whom asymptomatic bacteriosperms with a concentration of 10(5)/ml or higher could be shown despite an antibiotic directed therapy in which no count reduction was observed, were examined in the Dept. for Dental Prosthetics. A lot of intraoral foci were found, which got eliminated. Intra-operational bacterial specimens were taken and evaluated by a special diagnostic technique in the Dept. of Microbiology. It was shown, that the bacterial spectrum of the intraoral specimens and the spermiograms were identical. 6 months after completion of the dental therapy and intensive oral hygiene instructions a new andrological examination was performed. Two thirds of the spermiograms were already sterile. A direct causal relationship between dental primary diseases and asymptomatic bacteriosperms, which probably leads to subfertility, must be concluded.
