Male condoms
Male condoms (also called external condoms) are available in a variety of sizes and shapes and are usually made of latex, but nonlatex versions are available. They provide effective protection from sexually transmitted diseases and have few contraindications. For a summary of the characteristics of male condoms, see Comparison of barrier methods of contraception.
Male condoms are prelubricated, but additional water- or silicone-based lubrication may be applied to the outside. Oil-based lubricants increase the risk of condom breakage and should not be used.
Male latex condoms are contraindicated if either partner has a latex allergy. Nonlatex condoms are an alternative but are more expensive.
Some intravaginal medications (eg some topical thrush treatments, clindamycin cream, imiquimod cream) can weaken latex and polyisoprene condoms if used in the preceding 72 hours. Metronidazole gel, intravaginal estrogen cream or pessaries and the contraceptive vaginal ring do not weaken condoms.
