[Occurrence of trichomoniasis in women with intra-uterine devices (author's transl)].

The authors investigated the biocenosis in the vaginas of 216 women with IUD and 124 controls without any contraceptive. The incidence of vaginal trichomoniasis in IUD probands was higher with significance than that among the controls. Culture testing is indispensable to rule out the presence of vaginal trichomoniasis. Parasites were not readily detectable from stained and native specimens unless infections were massive. The cytological findings recorded from the above probands were within the normal. Knowledge is inadequate on the risk of infection of women with IUD. This should be another reason for which to improve public health education.
