Bacterial vaginosis (BV) may be common among women who report having sex with women (WSW) and frequently occurs in both members of monogamous couples. The results of Gram staining of a vaginal smear were consistent with BV in 81 (25%) and intermediate in 37 (11%) of 326 WSW included in this study. Lactobacilli were detected in 64% of subjects, and 42% of subjects had H(2)O(2)-producing strains. BV was associated with a higher lifetime number of female sex partners, failure to always clean an insertive sex toy before use, and oral-anal sex with female partners. Neither recent douching nor sexual practices with male partners were associated with BV. Vaginal smears from each partner were concordant in 55 (95%) of 58 monogamous couples; BV was present in both partners in 16 couples (28%) (P<.001, compared with expected distribution). BV was common among subjects who did not douche, who did not have concurrent sex with male partners, or who did not have a new sex partner, which suggests that other risk factors for BV exist. These data support the hypothesis that sexual exchange of vaginal secretions is a possible mechanism for acquisition of BV.
Genital infection with human papillomavirus (HPV), as determined by polymerase chain reaction detection of HPV DNA and prevalence of HPV-6 and -16 serum antibodies, was investigated in 149 women who were sexually active with women. By use of HPV L1 consensus primers and hybridization to types 6/11, 16, 18, 31/33/35/39, and 45 and a generic probe, HPV DNA was detected in 30% of subjects; of these, 20% had type 31/33/35/39, 18% had type 16, and 2% had type 6/11. Of 21 subjects reporting no prior sex with men, HPV DNA was detected in 19% and squamous intraepithelial lesions in 14%. By capture ELISA with HPV-6 and -16 L1 capsids, 47% of subjects were seropositive for HPV-16 and 62% for HPV-6. Current smoking was associated with detectable HPV DNA. Genital HPV infection and squamous intraepithelial lesions are common among women who are sexually active with women and occur among those who have not had sex with men.
A B S T R A C TObjectives. The purpose of this study was to examine frequency of and attitudes toward Papanicolaou (Pap) test screening in women who have sex with women (WSW) and to determine prevalence of genital human papillomavirus (HPV).Methods. Women were eligible if they reported having engaged in sex with another woman in the preceding year. Medical and sexual histories were obtained. Cervical specimens for Pap tests and cervical and vaginal specimens for HPV DNA testing were collected.Results. HPV DNA was detected in 31 of 248 WSW (13%). Women who had never had sex with men were less likely to have undergone pelvic examinations and had fewer recent Pap tests. Reasons for not undergoing Pap tests included lack of insurance, previous adverse experiences, and belief that Pap tests were unnecessary.Conclusions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
