Although recent meta-analyses of condom effectiveness suggest that condoms are 60 to 70% effective when used for HIV prophylaxis, these studies do not isolate consistent condom use, and therefore provide only a lower bound on the true effectiveness of correct and consistent condom use. A reexamination of HIV seroconversion studies suggests that condoms are 90 to 95% effective when used consistently, i.e. consistent condom Cited by: Mar 25, · Condoms for HIV prevention Condoms, when used correctly and consistently, are highly effective in preventing HIV and other sexually transmitted infections (STIs). A large body of scientific evidence shows that male latex condoms have an 80% or greater protective effect against the sexual transmission of HIV and other STIs.
Results: Among MSM reporting any anal sex with an HIV-positive male partner, we found 70% effectiveness with reported consistent condom use (compared with never use) and no significant protection when comparing sometimes use to never use. This point estimate for MSM was less than the 80% effectiveness estimate reported for heterosexuals in HIV-discordant couples Cited by: Laboratory studies have shown that latex condoms provide an effective barrier against even the smallest STD pathogens. Epidemiologic studies that compare rates of HIV infection between condom users and nonusers who have HIV-infected sex partners demonstrate that consistent condom use is highly effective in preventing transmission of HIV. Similarly, epidemiologic studies have shown that condom use reduces the risk .
Condom effectiveness for STD and HIV prevention has been demonstrated by both laboratory and epidemiologic studies. Evidence of condom effectiveness is also based on theoretical and empirical data regarding the transmission of different STDs, the physical properties of condoms, and the anatomic coverage or protection provided by condoms. Despite condom use being the most protective measure against the transmission of human immunodeficiency virus (HIV), little is known about the intermediary relationships between condom negotiation, assertive sexual communication, and condom use efficacy. The purpose of the current study was to exami .
condom effectiveness during anal sex between MSM in 2 prospective cohort studies of HIV incidence by self-reported consistency of use. Methods: Analyzed data combined from US participants in the EXPLORE trial (–) public use data set and in the VAX trial (–) data set. Initially, HIV-uninfected MSM enrolled in these trials completed baseline and semiannual interviews. Johnson WD et al. Per-partner condom effectiveness against HIV for men who have sex with men.
