David A. Eschenbach, Dorothy L. Patton, Thomas M. Hooton, Amalia S. Effects of a single episode of intercourse on vaginal flora and epithelium were examined in subjects randomly assigned to groups that used no condom or lubricated nonspermicide condoms. Subjects were evaluated at visits before 1 month and 1—2 days and after 8—12 h, 2—3 days, and 6—8 days an index episode of sexual intercourse.
Intercourse was not associated with gross, colposcopic, or histologic vaginal epithelial abnormalities. Unprotected sexual intercourse facilitates the transmission of sexually transmitted diseases STDsincluding human immunodeficiency virus HIV. This has drawn attention to infections, flora, and epithelial factors in the female genital tract that could enhance or decrease heterosexual HIV transmission [ 4—6 ].
Increased acquisition of HIV appears to occur with a wide variety of sexually transmitted cervical infections Neisseria gonorrhoeae [ 67 ] and Chlamydia trachomatis [ 6 ] and vaginal infections not Detroit red wing symbol sexually transmitted e.
The absence of So low pants website organisms also appears to be vahinal factor in the acquisition of HIV [ 9 ]. In addition, Trichomonas vaginalis is associated with an increased hazard ratio for the acquisition of HIV, although the findings often do not reach statistical significance [ 6—8 ].
Glrl use of a condom could reduce the transmission of all of these microbes, condom use has been Girl doing vaginal intercourse as an effective method to prevent HIV transmission [ 45 ]. Previous studies showed that intercourse with condoms lubricated with nonoxynol-9 and nonlubricated condoms increases the risk of urinary tract infection UTI [ 10—12 ].
Intercourse without condoms is also associated with increased Escherichia coli colonization of the vagina and bacteriuria [ 13 ]. Intercouese, studies have not compared the effect of no condom use with condom use on vaginal epithelium. Here we report the effects of a single index episode of vaginal intercourse in 2 randomly selected Girl doing vaginal intercourse groups: one without a condom and one with a silicone-lubricated condom lacking nonoxynol We examined vaginal flora and vaginal epithelium by gross, colposcopic, and histologic means in women without a bacterial or fungal genital infection, except for bacterial vaginosis.
From March to Mayfemale subjects were enrolled from the University of Washington student and staff population. Subjects were recruited through newspaper ads, flyers, and word-of-mouth referrals. Women were eligible for study if they were 18—40 Gurl old, had regular monthly menses, 1 sex partner, used combination oral contraceptive pills or permanent contraception, and agreed to refrain from vaginal medication.
Exclusion criteria were the following groups of factors: 1 complaints of vaginitis, abnormal Giro discharge, vulvar pruritus, or irritation; 2 chronic illness such as hypertension or diabetes; 3 current use of spermicides or an intrauterine device; 4 antibiotic use in the past month; 5 vaginal suppository or douching in the past week; and 6 allergy to latex.
We also excluded subjects who, at baseline, had N. Asymptomatic bacterial vaginosis was not an exclusion criterion, and subjects with asymptomatic bacterial vaginitis during the study were not treated. Demographic, sexual, contraceptive, and gynecologic history, including current genital symptoms, were collected on standardized forms at enrollment.
Women were asked to refrain from intercourse for 2—5 days before examination at visits 1 and 2. Visit 1 occurred 19—24 days after the last menstrual period, and visit 2 occurred 1 month later 15—22 days from the last menstrual periodso that the vaginal biopsy performed after intercourse was done at a similar time in the menstrual cycle 19—24 days.
At visit 1, subjects were randomized to the condom or no condom group by computer-generated random numbers table. After visit 2, subjects were asked to have 1 episode of vaginal intercourse in the next 1—2 days and to return for examination at visit dong 8—12 h after intercoursevisit 4 3—4 days after intercourseand visit 5 6—8 days after intercourse after the index episode of intercourse. Subjects refrained from intercourse between visits 3 and 5. At the follow-up visits, we obtained an interval sexual and gynecologic history and performed vaginal and cervical examinations.
A midstream clean catch urine was collected for culture before each examination. A second vaginal biopsy was done at visit 3 8—12 h after intercourse. At each visit, external genitalia were visually examined. A nonlubricated speculum was inserted for visual and colposcopic examination Giel the vaginal walls.
The amount of vaginal discharge was qualitatively assessed voing was recorded. The vaginal posterior fornix was swabbed, and the swabs were placed in transport media Port-A-Cul; Becton Dickinson and were cultured for aerobic and anaerobic bacteria within 12 h, as reported elsewhere [ 18 ]. Hydrogen peroxide H 2 O 2 —producing lactobacilli were identified by the blue pigment formed when H 2 O 2 oxidizes tetramethylbenzidine present in brucella agar base [ 19 ]. Cervical samples for cytology and for C.
A full-thickness biopsy was obtained of the vaginal epithelium in the upper one-third of the vagina at visits 1 and 3, as described elsewhere [ 21 ]. We removed a 2- by 4-mm full-thickness sample of vaginal epithelium by cervical biopsy forceps Mini-Townsend; Cooper Surgical.
Biopsy tissue was pinned flat on styrofoam to minimize distortion during formalin fixation. One of us D. Data are shown as a mean of the 2 fields. Thus, a 0. Included in this model were E. For tables 2—5statistical analyses were based on trend over time in the same subject. Subject demographic and reproductive history characteristics at baseline in no condom and condom group. Clinical examination data before and after an index episode of vaginal intercourse IC in groups that did not use or did use condoms.
Vaginal microflora except for facultative gram-negative bacteria before and after Dreier sex geschichte index episode of intercourse IC by groups that did not or did use condoms. Comparison of selected vaginal gram-negative rods GNRs before and after index episode of intercourse IC with and without a condom.
Comparison of urinary gram-negative rods GNRs before and after an Gir, episode of intercourse IC with and without a condom. The groups were similar in all demographic characteristics examined. The groups had similar smoking, alcohol, sex, and contraceptive histories. To prevent pregnancy during the study, all but 1 subject in the no condom group used oral contraceptives that woman had a tubal ligation.
There were no differences between the 2 groups in current genital symptoms or menstrual history data not shown. There were no significant differences in gross or imtercourse abnormalities of the vagina, amount of vaginal discharge, or viscosity of vaginal discharge between groups data not shown. The presence of erythema decreased by visit 4 in both groups.
The visual and colposcopy appearance of the vagina and the mean vaginal pH did not change after intercourse in either group. The mean number of epithelial cell layers of the vaginal mucosa and the mean number of neutrophils per 5 high-powered fields were similar before and after intercourse in both groups. The presence of lymphocytes and plasma cells also did not change in the vaginal submucosa between visits 1 and 3 in either group data not shown.
Lactobacilli and other microbes occurred at baseline in a similar concentration in the no condom and the condom groups. Vaginal microflora before and after index intercourse Table 3 lists all vaginal Vintage babe nature before and after the index episode of intercourse in the no condom and condom groups, except for facultative gram-negative rods GNRs.
No significant change in these vaginal microorganisms occurred between visit 3 8—12 h after intercourse and visits 1 not shown and 2 in the groups without or with condoms. We used logistic regression analysis to examine the presence of lactobacilli by visit number and by no condom and condom groups but found no difference in the prevalence of lactobacilli by visit between groups.
In the no condom group, a significant increase occurred in the proportion of subjects with E. A vaginla linear decrease also occurred in the proportion of subjects with E.
In the condom group, a slight increase occurred in the proportion of subjects with vaginal E. In the condom group, no significant change occurred in the number of subjects with a high concentration of either E coli or GNRs after intercourse. Subjects were randomly assigned to the groups, and it was possible to address the question of whether vaginal E. We developed a logistic regression model to compare the presence of E.
In these analyses, we confirmed that the prevalence of E. However, there was no significant difference in the prevalence of vaginal E. These analyses also allowed us to examine whether lactobacilli in the vagina protected against E. In the no condom group, H 2 O 2 -producing lactobacilli were not associated with vaginal E. In the no condom group, a statistically significant increase occurred in the proportion of subjects with E.
In the condom group, there was a slight, but not statistically significant, increase in the proportion of subjects with Ge kitchen bath sealant silicone. All but 1 subject had E. The potential effects of vaginal intercourse on vaginal physiology are important to doung since STD and UTI are associated with intercourse.
Intercourse could lead to trauma of vaginal epithelium that, in turn, would increase the ability of microbes to attach, colonize, and cause infection. Although condoms protect against STD infectious agents, including HIV, an examination was needed for potential adverse effects of condoms, such as trauma, on the vaginal physiology [ 12 ]. We observed virtually no vaginal erythema or lesions of the vaginal epithelium after intercourse without or with condoms, although vulvar erythema increased vagial both Free jap video porn. The mean number of epithelial cell layers and the number of subepithelial polymorphonuclear leukocytes were not altered by intercourse in either group.
In addition, we observed no colposcopic evidence of intercourse-related trauma to the cervix in either the condom or no condom group. Ectopy consists of only a few cell layers of epithelium between the surface and blood vessels, compared with the 26—28 squamous cells layers in the vagina [ 22 ]. Lactobacilli use glycogen to produce lactic acid, which helps maintain both the low pH and the dominance of lactobacilli and other acidophilic bacteria in the vagina [ 2526 ].
The low pH of the vagina is also maintained by lactic acid production by vaginal epithelial cells. The pH of the vagina is reported to have a buffer inercourse, so one would predict that semen with a pH of 7—8 in the vagina would be buffered back to the baseline pH, probably the reason that our subjects who did not use condoms had only a small insignificant increase in vaginal pH at 8—12 h after intercourse.
Intercourse with or without a condom had no effect on vaginal lactobacilli, which suggests that semen does not adversely impact vaginal colonization with lactobacilli. This is of interest, since the production of H 2 O 2 by lactobacilli appears to represent an important mechanism by which lactobacilli maintain their dominance over other vaginal flora [ 25 ].
The H 2 O 2 produced baginal lactobacilli may inhibit or kill other vaginal flora, particularly flora that lack or have low levels of H 2 O 2 -scavenging enzymes, such as catalase [ 26 ]. It is possible that H 2 O 2 -producing lactobacilli decrease the risk of HIV acquisition by directly killing free virus present in the vagina at intercourse, preventing bacterial vaginosis [ 25 ], which is associated with an increased risk of HIV acquisition [ 68 ], and by vvaginal to maintain intercohrse low pH in the vagina, which may inhibit HIV [ 27 ].
These findings do doijg appear to be by chance. First, subjects were analyzed by logistic regression for correlated data in which the subjects were used as their own control subjects. The prevalence of E. Second, a parallel increase in E. Of interest, in the condom group, H 2 O 2 -producing lactobacilli appeared to suppress E. These findings also ijtercourse that intercourse without a condom introduces some male factor not present with condom use that reduces the suppressive effect of H 2 O vaginap -producing lactobacilli on E.
These findings are compatible with previous findings that intercourse is associated with a transient increase of E.
