Background. Circumcision and lower human papillomavirus (HPV) viral loads in men are possibly associated with a reduced risk of HPV transmission to women. However, the association between male circumcision and HPV viral load remains unclear.Methods. Swab specimens from the glans and shaft of the penis were collected from men enrolled in a circumcision trial in Kisumu, Kenya. GP5+/6+ polymerase chain reaction (PCR) was used to identify HPV DNA types. HPV-16 and HPV-18 loads were measured with a LightCycler real-time PCR and classified as high (>250 copies/scrape) or low (≤250 copies/scrape).Results. A total of 1159 men were randomly assigned to undergo immediate circumcision, and 1140 men were randomly assigned to the control arm (these individuals were asked to remain uncircumcised until the study ended). The hazard of acquisition of high-viral load infections in the glans was lower in the circumcision arm, compared with the control arm, for HPV-16 (hazard ratio [HR], 0.32 [95% confidence interval {CI}, .20–.49]) and HPV-18 (HR, 0.34 [95% CI, .21–.54]). The 6-month risk of HPV persistence among men with high-viral load infections in the glans at baseline was lower in the circumcision arm, compared with the control arm, for HPV-16 (risk ratio [RR], 0.36 [95% CI, .18–.72]) and HPV-18 (RR 0.34 [95% CI, .13–.86]). Weaker and less precise results were obtained for shaft samples.Conclusions. Male circumcision could potentially reduce the risk of HPV transmission to women by reducing the hazard of acquisition, and the risk of persistence of high-HPV viral load infections in the glans in men.

Background. We estimated the 72-month efficacy of medical male circumcision (MMC) against herpes simplex virus 2 (HSV-2) incidence among men in the Kisumu MMC randomized trial.Methods. From 2002 to 2005, 2784 men aged 18–24 were enrolled and randomized 1:1 to immediate circumcision or control. Cox proportional hazards regression incorporating stabilized inverse probability of treatment and censoring weights generated through marginal structural modeling was used to estimate the efficacy of MMC on HSV-2 risk. Conventional conditional Cox regression identified multivariable risks for HSV-2 seroconversion.Results. Among 2044 HSV-2 seronegative men at baseline, the cumulative 72-month HSV-2 incidence was 33.5% (32.7% among circumcised men, 34.6% among uncircumcised men). In weight-adjusted Cox regression, the hazard ratio was 0.88 (95% confidence interval, .77–1.10). In multivariable analyses, risks for HSV-2 included human immunodeficiency virus (HIV) infection, genital ulcer disease (GUD), penile epithelial trauma, multiple recent sex partners, and being married /cohabiting.Conclusions. MMC had no effect on acquisition of HSV-2 during 72 months of follow-up. The temporal sequence and limited correlation between HSV-2, GUD, and penile epithelial trauma suggests that these are distinct phenomena rather than misclassification of HSV-2 symptoms. Determining the etiology of non–sexually transmitted infection GUD and penile epithelial trauma is needed, as both are commonly occurring risks for HSV-2 and HIV acquisition.Clinical Trials Registration.

Purpose: Injuries to the penis during intercourse represent a hypothesized mechanism by which uncircumcised men are at increased risk for HIV. There are no published, systematically collected data regarding mild penile coital trauma to our knowledge. We identified risks of self-reported penile coital injuries in men 18 to 24 years old in a randomized trial of circumcision to prevent HIV in Kisumu, Kenya. Materials and Methods: Each participant underwent standardized interview, medical history and physical examination at baseline, and 6, 12, 18 and 24 months after enrollment. Self-reported penile coital injuries were assessed at each visit, and were defined as penis feels sore during sex, penis gets scratches, cuts or abrasions during sex, and skin of the penis bleeds after sex. Generalized estimating equation analysis estimated odds ratios for penile coital injuries. Results: From February 2002 to September 2005, 2,784 participants were randomized. At baseline 1,775 (64.4%) men reported any coital injury including 1,313 (47.6%) soreness, 1,328 (48.2%) scratches, abrasions or cuts and 461 (16.7%) bleeding. On multivariable analysis coital injury risk was lower for circumcised than for uncircumcised men with soreness (OR 0.71, 95% CI 0.64–0.80), scratches/abrasions/cuts (OR 0.52, 95% CI 0.46–0.59), bleeding (OR 0.62, 95% CI 0.51–0.75) and any coital injury (OR 0.61, 95% CI 0.54–0.68). Other significant risks included increasing age, multiple recent sex partners, HSV-2 seropositivity and genital ulcers (p <0.05). Condom use, cleaning the penis soon after intercourse and being married/cohabiting were protective (p <0.05, each). Conclusions: Self-reported penile coital injuries were common in these healthy young men. Circumcised men were at lower risk for coital injuries. Verifying penile coital injuries, the mechanism of acquisition and the association with HIV risk is needed. [Copyright &y& Elsevier]

Background. We examined the effect of male circumcision on the acquisition of 3 nonulcerative sexually transmitted infections (STIs). Methods. We evaluated the incidence of STI among men aged 18-24 years enrolled in a randomized trial of circumcision to prevent human immunodeficiency virus (HIV) infection in Kisumu, Kenya. The outcome was first incident nonulcerative STI during 2 years of follow-up. STIs examined were laboratory-detected Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis infection. Results. There were 342 incident infections among 2655 men followed up. The incidences of infection due to N. gonorrhoeae, C. trachomatis, and T. vaginalis were 3.48, 4.55, and 1.32 cases per 100 person-years, respectively. The combined incidence of N. gonorrhoeae and C. trachomatis infection was 7.26 cases per 100 person-years (95% confidence interval, 6.49-8.13 cases per 100 person-years). The incidences of these STIs, individually or combined, did not differ by circumcision status as a time-dependent variable or a fixed variable based on assignment. Risks for incident STIs in multivariate analysis included an STI at enrollment, multiple sex partners within <30 days, and sexual intercourse during menses in the previous 6 months; condom use was protective. Conclusions. Circumcision of men in this population did not reduce their risk of acquiring these nonulcerative STIs. Improved STI control will require more-effective STI management, including partner treatment and behavioral risk reduction counseling. [ABSTRACT FROM AUTHOR]

The article focuses on the study concerning the penile HPV infection which found in young men in Kisumu, Kenya. The HPV infection was identified as the cause of invasive cervical cancer in women, and men was considered as important in the etiology of invasive cervical cancer. According to the study, a total of 98 young men HIV-seronegative, has participated the circumcising. The penile HPV prevalence was varied by anatomical site including the 50% in penile exfoliated cells from glans, coronal sulcus, and 43% in inner fore-skin tissue.

The article presents the study on how to prevent Sexually Transmitted Infection (STI) which aimed to reduce HIV cases among young men in Kisumu, Kenya. The country's men aged 18 to 24 were interviewed for sociodemographic and behavioral risk to randomize trial of male circumcision. It is inferred that Neisseria Gonorrhoeae (NG) and Chlamydia Trachomatis (CT) were determined by polymerase chain reaction which attempt to Trichomas Vaginalis (TV) by culture. According to the study, among 2743 men in the country, 214 was infected with STI. The author implied that the significant risk for infection was due to opting dry sex, HSV-2 seropositivity, and inability to ejaculate during sex.

The article presents a randomized controlled trial of young men in Kisumu, Kenya that examined whether male circumcision protected against HIV infection. The men were assessed by HIV testing, medical examinations, and behavioral interviews. The authors found that male circumcision does significantly reduce the risk of acquiring of HIV in young men in Africa. The authors recommend that voluntary, safe, and affordable male circumcision services be integrated with other HIV preventive interventions as quickly as possible.

In a combined study from the USA and Kenya, the safety of adult male circumcision in the latter country was reviewed, particularly with the purported association between this procedure and a lower incidence of HIV and other sexually-transmitted infections. It was found that safe and acceptable adult male circumcision services could be delivered in developing countries should this be advocated as a public health measure. OBJECTIVE To develop a standard procedure for male circumcision in a resource-poor medical setting and prospectively evaluate the outcome in a randomized, controlled trial with the incidence of human immunodeficiency virus (HIV) as the main outcome, as studies suggest that circumcision is associated with a lower incidence of HIV and other sexually transmitted infections in high-risk populations. SUBJECTS AND METHODS Healthy, uncircumcised, HIV-seronegative men aged 18–24 years from Kisumu District, Kenya, were offered participation in a clinical trial using a standard circumcision procedure based on ‘usual’ medical procedures in Western Kenya. The follow-up included visits at 3, 8 and 30 days after circumcision, with additional visits if necessary. Healing, satisfaction and resumption of activities were assessed at these visits and 3 months from randomization. RESULTS Overall, 17 (3.5%) of the 479 circumcisions were associated with adverse events judged definitely, probably or possibly related to the procedure. The most common adverse events were wound infections (1.3%), bleeding (0.8%), and delayed wound healing or suture line disruption (0.8%). After 30 days, 99% of participants reported being very satisfied with the procedure; ≈ 23% reported having had sex and 15% reported that their partners had expressed an opinion, all of whom were very satisfied with the outcome. About 96% of the men resumed normal general activities within the first week after the procedure. CONCLUSION Safe and acceptable adult male circumcision services can be delivered in developing countries should male circumcision ultimately be advocated as a public-health measure.

Introduction. Male circumcision is being promoted for HIV prevention in high-risk heterosexual populations. However, there is a concern that circumcision may impair sexual function. Aim. To assess adult male circumcision's effect on men's sexual function and pleasure. Methods. Participants in a controlled trial of circumcision to reduce HIV incidence in Kisumu, Kenya were uncircumcised, HIV negative, sexually active men, aged 18–24 years, with a hemoglobin ≥9.0 mmol/L. Exclusion criteria included foreskin covering less than half the glans, a condition that might unduly increase surgical risks, or a medical indication for circumcision. Participants were randomized 1:1 to either immediate circumcision or delayed circumcision after 2 years (control group). Detailed evaluations occurred at 1, 3, 6, 12, 18, and 24 months. Main Outcome Measures. (i) Sexual function between circumcised and uncircumcised men; and (ii) sexual satisfaction and pleasure over time following circumcision. Results. Between February 2002 and September 2005, 2,784 participants were randomized, including the 100 excluded from this analysis because they crossed over, were not circumcised within 30 days of randomization, did not complete baseline interviews, or were outside the age range. For the circumcision and control groups, respectively, rates of any reported sexual dysfunction decreased from 23.6% and 25.9% at baseline to 6.2% and 5.8% at month 24. Changes over time were not associated with circumcision status. Compared to before they were circumcised, 64.0% of circumcised men reported their penis was “much more sensitive,” and 54.5% rated their ease of reaching orgasm as “much more” at month 24. Conclusions. Adult male circumcision was not associated with sexual dysfunction. Circumcised men reported increased penile sensitivity and enhanced ease of reaching orgasm. These data indicate that integration of male circumcision into programs to reduce HIV risk is unlikely to adversely effect male sexual function.

The article examines the sexual practices and risk factors for prevalent human immunodeficiency virus (HIV) infection among young men in Kisumu, Kenya. As part of the experimental design, lifetime sexual histories were collected from a sample of 1337 uncircumcised subjects within the randomized controlled trial of male circumcision to reduce HIV incidence. The results showed 65 men or 5% of the participants tested were positive for HIV. Meanwhile, the researchers concluded that the analysis confirmed the importance of established risk factors for HIV and identified practices that needed further investigation.

The article discusses the results of the sub study of a randomized clinical trial in Kisumu, Kenya designed to evaluate the effect of adult male circumcision on sexual function, sexual pleasure and penile coital injuries. Sexually active men in the area, ages 18 to 24 years, were enrolled in a randomized, controlled trial of adult male circumcision. Based on the results, there was no difference in sexual function or sexual pleasure between circumcised and uncircumcised men and that circumcision does not affect male sexual function.
