[Incidence of the Blastomyces and Trichomonad infections during the use of hormonal and intrauterine contraception].
The vaginal smear of 200 women treated with hormonal contraceptives (group A), of 45 women using an IUD (group B) and of 220 women representing an untreated control group (group C) was investigated on infection with vaginal yeasts and trichomonads. It was found, that infection with vaginal yeasts in women of group A was significantly higher (23,7%), than in women of group B (9,0%) and group C (9,5%). The occurance of trichomonads was also different between the groups. It was about 6,6% in group B and 6,8% in group C but only 2,1% in group A. From these results we concluded, that hormonal contraceptives on vaginal yeast infections act as a stimulating factor.
