There are so many methods of birth control like condoms, pills, surgeries etc... And the latest entry in the list of birth control options is contraceptive sponge, which is proved to be 90% effective when it comes to the result.
Contraceptive sponge is a small, doughnut-shaped device that is coated with spermicide. The sponge is moistened with water and inserted into the vagina. It is made of polyurethane foam that feels like natural vaginal tissue.
The device works in this way, It releases a spermicide to kill sperm cells, it traps and absorbs semen before the sperm have a chance to enter the cervix and it acts as a barrier between the sperm and the cervix.
The good with the method is that the sponge provides a continuous presence of spermicide throughout a 24-hour period, allowing for multiple acts of intercourse within that time frame without the need for additional spermicide.[an error occurred while processing this directive]
Contraceptive sponge combines barrier and spermicidal methods to prevent conception. There are so many brands marketing different types of contraceptive sponges.
The sponges are inserted vaginally prior to intercourse and must be placed over the cervix to be effective. It is important to note that none these sponges provide protection from sexually transmitted diseases. These are only birth control methods to prevent pregnancy.
Sponges are found effective if used in the right way as prescribed. A minor fault in the operation can let the sperms reach the cervix and thus cause a pregnancy. Sponges, in this way, are not as reliable as condoms or any other pills. But if inserted in the right way it can prevent pregnancy effectively.
Sponges are a physical barrier, trapping sperm and preventing their passage through the cervix into the female reproductive system. The spermicide is an important component of pregnancy prevention; each brand offers a different formula.
