Though seemingly simple, a certain protocol needs to be followed when using a condom for contraception

1. A new condom should be used for every act of coitus.
2. Condoms are available in pre-tested, pre-sterilized packs and need not be tested prior to use.
3. It is to be rolled onto the erect penis just prior to insertion. Practice of delaying and putting it on just before ejaculation should be avoided.
4. It should be removed immediately after ejaculation otherwise the penis becomes flaccid and the semen is likely to spill into the vagina.
5. For removal, it is to be held on to the base of the penis, and should be withdrawn along with the penis.
6. It may be used with some spermicidal jelly to maximize its contraceptive effect.
