A male condom is a thin sheath that covers the penis during intercourse and is made of one of the following materials:
- Rubber (latex).
- Plastic (polyurethane): the best alternative for people allergic to latex.
Male condoms can vary greatly in color, size and amount of lubrication and spermicide.
The male condom protects against sexually transmitted infection (STI) and pregnancy by covering the penis and preventing direct contact between the penis and vagina. Condoms collect the semen and prevent it from entering the vagina.
