From the CDC website:
Source: cdc.gov/condomeffectiveness/latex.htmLaboratory studies have demonstrated that latex condoms provide an essentially impermeable barrier to particles the size of HIV.
Theoretical basis for protection. Latex condoms cover the penis and provide an effective barrier to exposure to secretions such as urethral and vaginal secretions, blocking the pathway of sexual transmission of HIV infection.
Epidemiologic studies that are conducted in real-life settings, where one partner is infected with HIV and the other partner is not, demonstrate that the consistent use of latex condoms provides a high degree of protection.
