What is a contraceptive foam?

and contraceptive foam is a foam that is inserted in the vagina to prevent pregnancy. Foam is a spermicide, which means it kills sperm from a woman's sex partner. The use of contraceptive foam as a method of contraception is not as effective as the use of condoms or contraceptive pills.

Contraceptive foam contains both the carrier and the spermicidal agent, which is usually a chemical nonoxynol-9. Nonoxynol-9 kills the sperm and foam physically blocks the sperm on the vagina. Contraceptive foam protects against sexually transmitted disease.

In order to be effective, the foam must be inserted into the vagina no more than half an hour before sexual intercourse or otherwise indicated on the instructions of the product. Contraceptive foam comes in a bottle with the upper part of the applicator. The woman puts an applicator in the same way as her. Then release the foam from the container. Sometimes the foam can run, so if the product directs it, the woman should not walk for some time, leaving the foam to settle.

This spermicidal method is only effective only about 80 percent compared to approximately 95 % of condoms efficiency. Some women decide to use foam together with a condom to further reduce the risk of pregnancy and ensure protection from disease. There are several reasons why a woman would choose a contraceptive foam instead of a pill or condoms.

A woman can use the foam whenever she needs, and she doesn't have to remember her pill. It can also stop using foam whenever it wants to conceive. Another advantage of using foam is that a woman does not have to be numbered to her partner to wear a condom every time they have intercourse.

In some countries, non -c only foam does not require a prescription and can be obtained directly from the pharmacy.
