This chapter describes male latex condoms. Female condoms, which usually are plastic and inserted into a woman's vagina, are available in some areas (see Female Condoms and Comparing Condoms).

What Are Male Condoms?

• Sheaths, or coverings, that fit over a man's erect penis.
• Also called rubbers, “raincoats,” “umbrellas,” skins, prophylactics and preservativos; known by many different brand names.
• Most are made of thin latex rubber. Male condoms also are made from other materials, including polyurethane, polyisoprene, lambskin, and nitrile.
• Work by forming a barrier that keeps sperm out of the vagina, preventing pregnancy. Also keep infections in semen, on the penis, or in the vagina from infecting the other partner.
