QUESTION
Are polyurethane condoms any better than latex? Have there been any studies showing that they are more effective in stopping the transmission of HIV? I would prefer to use polyurethane because I can use oil-based lubricants with them.

ANSWER
I am not aware of any new evidence that polyurethane condoms are better than latex for the prevention of HIV or STDs. I would not expect any such studies because when used correctly and consistently, latex condoms are extremely effective, nearing 100%. In clinical studies it would be very difficult to prove any greater effectiveness.

The failure of either condom results when they are put on wrong, break, slip off or most commonly are not used. Fortunately, there are increasing condom choices including the latex condom, polyurethane condom and Reality (female) condom for receptive anal intercourse.
