It can be overwhelming to look at rows of condom boxes and not know if they all work equally well! The most important distinction you need to make between condoms is to understand their different material. Condoms can be made of latex, polyurethane or natural skin (also known as "lambskin"), and they can also be sold as "novelty" items.

Be sure to buy only latex or polyurethane condoms. Only these types of condoms prevent the spread of sexually transmitted diseases (STDs). Most studies have been conducted on latex condoms, but for people who are allergic to latex, polyurethane is also a good choice.
