It is made of latex, plastic (polyurethane) or a membrane of an animal which is unwrapped on a vertical penis before sex.

Norm of efficiency
Efficiency of a condom separately makes 85 percent. In other words, from 100 pairs which are protected by condoms within one year, 15 appear in result pregnant women. Efficiency of a condom raises up to 95 percent (5 pairs from 100 during one year will be pregnant women) at use of a condom together with a vaginal spermicide. Man's condoms can not protect in case of improper use, non-use, break or incorrectly picked up size. The most effective accessible method of a barrier is use of a condom with a vaginal spermicide.
Side effects and risk for health
Latex condoms can cause an allergy for some people. But the condoms made from polyurethane (plastic) or skin of an animal also are accessible. The condom is the most effective contraceptive method to avoid the illnesses transmitted in sexual way (STDs), accessible, also is a unique method which reduces your risk of an infection of a HIV. The condoms made of products of an animal do not guarantee such big protection because they have tiny pures through which viruses such as a HIV can pass, hepatitis B and a herpes. The condoms containing spermicide nonoxynol-9 sometimes cause irritation on the skin. In this case, your risk of an infection of a HIV can increase at use of a condom together with vaginal spermicide as the last can cause irritation of the skin too.
How correctly to use a condom
If you have chosen a condom as a method of contraception, put on it before penis enters a vagina. Carefulness, correctness and sequence are very important at use of condoms. Here are some additional helps for purchase, storages and uses of condoms:

• It is preferred to use greasing on the basis of water (K-Y, Astroglide, others), instead of greasing on the basis of oil because greasing on the basis of oil can become the reason of break of a condom or infiltration of sperm.
• A tip of the rolled condom place on a erect penis. The rolled rim should be on the overside.
• Hold a tip of a condom at deployment of a condom downwards to a basis of a penis.
• Any air bubbles smooth to make sure, that the size of a condom approaches. The air bubble could force to be torn or come off a condom.
• If the man is uncircumcised, make sure, that foreskin is withheld before to dress a condom.
• Condoms keep in a cool, dry place. Condoms, which have contact to air, high temperature and light, will more probably break. Do not hold condoms in purses, wallets, back pockets or glove compartment for a long time.
• Remove a condom right after sex. For each subsequent sexual act it is necessary to use a new condom.
