Cryotherapy compared with trichloroacetic acid in treating genital warts

Abstract

Fewer Trichomonas vaginalis organisms in vaginas of infected women during menstrua- tion Sir, A recent paper by Demes et al reports lower counts of Trichomonas vaginalis organisms in the vagina during menstruation.' The authors considered that this was caused by immunological factors within menstrual blood. Other explanations for this result could also be given. The menstrual flow may "flush out" the vagina and thus decrease the number of organisms present. No mention was made of the use of tampons, which absorb vaginal secretions and organisms. Constituents of tampons may alter vaginal microbiology. Finally, the raised vaginal pH during menstruation may also be a factor.
