Condoms: still the most popular contraceptive.

Abstract

Condoms can be used as a barrier contraceptive and/or to protect against many sexually-transmitted diseases. They are easy to buy and use and free from medical risk. Carefully used, and used in conjunction with a spermicide, condoms have similar reliability to IUDs, progesterone-only pills and the diaphragm. The condom must be put on before the penis touches the vaginal area. The penis should not touch the vaginal area after the condom has been taken off. Oil-based products, eg baby oil, massage oil, lipstick, petroleum jelly, suntan oil, can damage the condom. If a lubricant is required, use one that is water-based.
