When used properly, latex or polyurethane condoms prevent HIV transmission.
Condoms come in a variety of shapes and sizes. There are even flavored condoms. Which condom is most appropriate for any particular person is an individual choice. However, condoms made of natural membranes ("skin" or lambskin") may contain natural pores. They are therefore not recommended for to prevent transmission of HIV.
Since condoms are classified as medical devices, their manufacture is regulated by the Food and Drug Administration (FDA). Condom manufacturers in the United States test each latex condom for defects, including holes.
Every aspect of condom use is important: from storage through disposal. Therefore, we recommend that you read each section of the following.
If you have additional questions, ask your doctor or pharmacist.
