Refraining from having sexual intercourse with an infected partner is the best way to prevent transmission of HIV and other STDs. But for those who have sexual intercourse, latex condoms are highly effective when used consistently and correctly. In fact, recent studies provide compelling evidence that latex condoms are highly effective in protecting against HIV infection used for every act of intercourse. In a 2-year study of discordant couples in Europe, among 124 couples who reported consistent use of latex condoms, in one of the uninfected partners became infected. Condoms must be used consistently and correctly to provide maximum protection.
Consistent use means using a condom with each act of intercourse.
Put on the condom as soon as erection occurs and before any vaginal, anal, or oral contact with the penis. Hold the tip of the condom and unroll it onto the erect penis, leaving space at the tip of the condom, yet ensuring that no air is trapped in the condom's tip. Oil-based lubricants, such as petroleum jelly, cold cream, hand lotion, or baby oil, can weaken the condom. Withdraw from the partner immediately after ejaculation, holding the condom firmly to the base of the penis to keep it from slipping off. Myths about condoms Misinformation and misunderstanding persist about condom effectiveness.
