Background Sexual acquisition of HIV is influenced by choice of partner, sex act, and condom use. However, current risk-reduction strategies focus mainly on condom use. Goal To estimate the contribution of choice of partner, sex act, and condom use on the per-act relative and absolute risks for HIV infection. Study Design Per-act relative risk for HIV infection was calculated with use of estimates of HIV prevalence, risk of condom failure, HIV test accuracy, and per-act risk of HIV transmission… 

Condom Effectiveness for HIV Prevention by Consistency of Use Among Men Who Have Sex With Men in the United States

Estimates of male condom effectiveness during anal sex among men who have sex with men (MSM) are useful for counseling efforts and for modeling the impact and comparative effectiveness of condoms and other prevention methods used by MSM.

Per-partner condom effectiveness against HIV for men who have sex with men

The increase in odds of new HIV infection per HIV-positive partner for receptive anal intercourse was reduced by 91% for each partner with whom condoms were always used.

Use of a Rapid HIV Home Test to Screen Sexual Partners: An Evaluation of its Possible Use and Relative Risk

If MSM engage in AI without condoms following a non-reactive HT result, they have lower chances of becoming infected by someone still in the window period than by following heuristics and using condoms inconsistently.

The intent and practice of condom use among HIV-positive men who have sex with men in Japan.

Evaluation of the intent and practice of condom use among Japanese HIV-positive men who have sex with men (MSM) found willingness to protect sexual partners from HIV infection was strongly related not only to the intent but also to the practice.

Prevalence and correlates of condom use among sexually active men who have sex with men in the United States: findings from the National Survey of Family Growth, 2002, 2006-10 and 2011-13.

BACKGROUND Men who have sex with men (MSM) are disproportionately at risk of contracting HIV and other sexually transmissible infections (STIs). Correct and consistent condom use is the most

The Impact of Sexual Behaviours, Risk Perceptions and the Criminalization of HIV Non-Disclosure on HIV Transmission among HIV-Negative and HIV-Positive Men Who Have Sex With Men in Toronto

Perceived HIV risk increased significantly as condom use with an HIV-positive regular partner decreased, however, perceived HIV risk was not associated with condoms use with casual partners or HIV unknown status regular partners, even though these behaviours could be considered risky.

Reinforce educational interventions to deliver STI-HIV information,enhance the use of condoms, and to address specific contextual factors that facilitate condomless practice with commercial and non-commercial sexual partners.

Perceived risk and condomless sex practice with commercial and non-commercial sexual partners of male migrant sex workers in London, UK [version 1; peer review: 1 approved with reservations]

Education interventions to deliver STIHIV information, enhance the use of condoms, and to address specific contextual factors that facilitate condomless practice with commercial and non-commercial sexual partners are needed.

Sexual behaviour of HIV-diagnosed men who have sex with men in England in the era of effective antiretroviral therapy: results from the ASTRA study

Consideration of different types of CLS among HIV-diagnosed MSM demonstrated differing implications for prevention of HIV versus other STI transmission, with a need for focus on harm reduction in recreational drug use and prevention of STI co-infections.



Infectiousness of HIV between male homosexual partners.

The effectiveness of condoms in reducing heterosexual transmission of HIV.

The condom's efficacy at reducing heterosexual transmission may be comparable to or slightly lower than its effectiveness at preventing pregnancy, with a range depending upon the incidence among condom nonusers.

Man-to-woman sexual transmission of HIV: longitudinal study of 343 steady partners of infected men.

A cohort of 343 seronegative women, stable, monogamous partners of infected men whose only risk of acquiring HIV was sexual exposure to the infected partner, followed to study incidence and risk factors of heterosexually transmitted HIV infection.

Transmission of HIV to heterosexual partners of infected men and women.

Biological factors such as variability in infectivity of the index case and susceptibility of the contact, as well as behavioural variables may be important in determining transmission.

The real problem with male condoms is nonuse.

Based on the studies conducted on STD/HIV transmission, a frequently listed cause of condom failure was the type of condom being used during sexual intercourse and the user's failure to properly use the condom.

A Longitudinal Study of Human Immunodeficiency Virus Transmission by Heterosexual Partners

A prospective study of HIV-negative subjects whose only risk of HIV infection was a stable heterosexual relationship with an HIV-infected partner, finding that only 124 couples who continued to have sexual relations for more than three months after enrollment in the study, used condoms consistently for vaginal and anal intercourse.

Several factors which potentiate the risk of transmission through unprotected vaginal intercourse have been identified and knowledge of these factors could be helpful for counselling patients infected with HIV and their sexual partners.

Between-gender differences in the contact surfaces and the intensity of exposure to HIV during sexual intercourse are possible reasons for the difference in efficiency of transmission.
