Plastic condoms are resistant to these effects. Plastic condoms can be kept longer without breaking down in heat or cold. Another reason latex condoms break is because they aren't stored correctly. Latex breaks down if it has been exposed to heat or cold too long. People allergic or sensitive to latex can use plastic condoms.
Some people get a rash if their skin touches latex.
Not everyone will want to use new plastic condoms. Because they are new, scientists don't know as much about plastic condoms as they do about latex condoms. For example, they aren't sure how good plastic condoms are at stopping pregnancy. Scientists also are not sure how well plastic condoms can prevent the infections you can get from having sex. The reason they don't know how well plastic condoms can prevent pregnancy and infections is because not enough tests have been done with people.
