OBJECTIVE We sought to examine highly sexually active gay and bisexual men's accuracy in predicting their sexual behavior for the purposes of informing future research on intermittent event-driven HIV Pre-Exposure Prophylaxis. DESIGN For 30 days, 92 HIV-negative men completed a daily survey about their sexual behavior (n = 1688 days of data) and indicated their likelihood of having anal sex w...

While the risk of transmission through oral sex for men who have sex with men (MSM) is low, discrepancies remain between study findings and there is uncertainty about the exact degree of risk. Between July 2001 and September 2003, a total of 4150 MSM were newly diagnosed with HIV infection in England, Wales, and Northern Ireland and reported to the Communicable Disease Surveillance Centre in Lo...

To identify risk factors for HIV infection among men who have sex with men (MSM) and to provide a theoretical basis for prevention interventions. Between December 2011 and August 2012, a case-control study was conducted among MSM who underwent voluntary counselling and testing for HIV. Confirmed HIV-positive MSM were included in the case group, and HIV-negative MSM were included in the control ...

BACKGROUND The role of homosexuality and anal sex practices in the African HIV -1 epidemic is not well described. We aimed to assess the risk factors for prevalent HIV-1 infection among men who have sex with men (MSM) to guide HIV-1 prevention efforts. METHODS Socio-behavioural characteristics, signs and symptoms of sexually transmitted diseases (STD), and serological evidence of HIV-1 were d...

Methods Data on anal cancer cases with and without AIDS were obtained from the HIV/AIDS Cancer Match Study. The number of HIV-infected anal cancer cases without AIDS was estimated from the number of anal cancers occurring before diagnosis of AIDS. The proportion of anal cancer cases with HIV infection in the general population was calculated. We estimated temporal trends in the incidence rates ...

Infection with human papillomavirus (HPV), especially HPV16, is cen tral to the development of squamous anogenital cancers and their precur sor lesions, termed "squamous intraepithelial neoplasias." Men who have sex with men, particularly those who are infected with HIV, are at a high risk for anal infection with HPV16 and for low-grade anal neoplasia; however, only a subset of these men develo...

Infection with human papillomavirus (HPV), especially HPV16, is central to the development of squamous anogenital cancers and their precursor lesions, termed "squamous intraepithelial neoplasias." Men who have sex with men, particularly those who are infected with HIV, are at a high risk for anal infection with HPV16 and for low-grade anal neoplasia; however, only a subset of these men develop ...

BACKGROUND Men who have sex with men (MSM) are at high risk for HIV acquisition and transmission. There is a high HIV-transmission potential associated with unprotected anal intercourse (UAI), which requires sexual lubrication for comfortable, non-traumatic anal sex. Lubricant distribution remains poor in many developing nations and MSM have been known to substitute a number of common household...

This qualitative study investigates the different methods for selecting sex partners by Korean homosexuals considering factors related to homosexual identity and sexual behavior. We take the approach of the grounded theory to examine the issue of sexual partnering of men who have sex with men (MSM). In-depth interviews of urban MSM and bisexual men were conducted. The snowball sampled through a...

A probability sample of 206 men who have sex with men from 16 sites in Phnom Penh were surveyed about sexual behaviors and tested for HIV and sexually transmitted infections (STIs). HIV and syphilis prevalence was 14.4% and 5.5%, respectively. Out of the total sample, 81% reported anal sex with any male partners in the past 6 months, and 61.2% reported having had vaginal sex. In the past 6 mont...
