Resumen:
Objective: The aims of this study were to investigate the frequency of male circumcision among men who have sex with men(MSM) in Buenos Aires, Argentina; the association between circumcision and sexually transmitted infections (STIs); and, amongthose uncircumcised, the willingness to be circumcised.Methods: A cross-sectional study was conducted among 500 MSM recruited through the respondent-driven sampling (RDS)technique. Participants underwent a consent process, responded to a Web-based survey that included questions ondemographic information, sexual behaviour, and circumcision and provided biological samples. HIV, hepatitis B virus (HBV),hepatitis C virus (HCV), Treponema pallidum, and human papiloma virus (HPV) diagnoses were performed using standardmethodologies. For all analyses, data were weighted based on participants? network size.Results: Only 64 (13%) of the 500 MSM in our study reported being circumcised. Among uncircumcised men (n=418),302 (70.4%) said that they would not be willing to get circumcised even if the procedure could reduce the risk of HIV infection.When considering all participants, circumcision status was not significantly associated with HIV, HBV, HCV, T. pallidum or HPVinfections. However, when we restricted the sample to men who do not practice receptive anal intercourse (RAI) and comparedcircumcised to uncircumcised men, the former (N=33) had no cases of HIV infection, while 34 of 231 (14.8%) uncircumcisedmen were HIV positive (p=0.020). Regarding HPV, uncircumcised men had a significantly larger number of different HPV typescompared with circumcised men (mean 1.83 vs. 1.09, p<0.001) and a higher frequency of high-risk-HPV genotypes (47.6% vs.12.5%, p=0.012).Conclusions: Consistent with international evidence, male circumcision appears to have a partial protective effect among MSM.The efficacy of circumcision in reducing risk of HIV infection among MSM appears to be correlated with sexual practices. Giventhe lack of motivation among MSM with regard to circumcision, proper awareness on the risks and benefits of circumcisionneeds to be created, if circumcision has to be introduced as a prevention strategy.
