Extensive literature on the efficacy and
safety of various contraceptive methods already
exists, while the effects of these methods on vaginal
flora is less certain and are yet to be substantiated.
The aim of this study was to investigate the effect of
the contraceptive method on the prevalence of
vaginal infection by using the Papanicolaou staining
method. The study group consisted of 759
consecutive women attending the outpatient
gynecology clinic of a tertiary center for various
reasons. Four groups of contraceptive methods were
defined: Coitus interruptus, condom, combined oral
contraceptive, and intrauterine device. Coitus
interruptus group was used as comparison group.
There were no significant differences among the
groups regarding Candidiasis and Trichomonas
Vaginalis rates. Bacterial vaginosis rate was similar
in coitus interruptus and intrauterine device groups;
while it was significantly reduced in condom and
combined oral contraceptive groups. Intrauterine
device use was not associated with bacterial
vaginosis. The results demonstrate the necessity of
frequent clinical attendance and laboratory tests for
women using contraceptive methods.
