Bacteriospermia requiring medical treatment were diagnosed in more tha
n 70% of the subfertile patients who had since 1988 attended the gynec
ological clinic at the RWTH hospital in Aachen. In 23% of all cases sp
ecific treatment with antibiotics did not reduce the concentrations of
bacteria in sperma. Thirty-six patients with bacteriospermia resistan
t to antibiotic therapy were then subjected to dental examination. A h
igh incidence of potential dental foci was found in all patients. In a
test group of 18 patients these sources of potential infection were e
liminated. Between dental operations and therapy swabs were taken to d
etermine bacterial levels and bacteriological composition. It could be
demonstrated that the bacterial spectrum of the intraoral samples was
almost identical with the spermiograms. Six months following completi
on of dental treatment a further spermiogram analysis was carried out.
In the test group about two thirds of the spermiograms proved sterile
. Spermatological parameters, such as motility, density and morphology
, had also clearly improved. In the control group the findings of the
spermiogram remained poor. This study indicates that a direct causal r
elationship exists between bacterial colonies (dental foci) and therap
y-resistant bacteriospermia which probably leads to subfertility.
