Polyurethane condoms are one of the newest options for people who are allergic to traditional latex condoms. Polyurethane is stronger than latex and therefore can be made much thinner and still be just as reliable. Condoms made of polyurethane also transmit body heat more effectively than latex condoms and therefore most folks find polyurethane condoms more pleasurable to wear.
Please note: You may use polyurethane condoms if you or your partner are allergic to latex. If you and your partner are not allergic to natural latex rubber, it is recommended that you use a latex condom.
The risks of pregnancy and sexually transmitted diseases (STDs) including AIDS (HIV infection) are not known for polyurethane condoms. Studies are being done. That said, laboratory tests on this material have shown that organisms even as small as sperm and viruses like HIV cannot pass through it.
