Condoms have a birth control failure rate of about 15 percent. Most of the failures can be traced to improper use. Some condoms have spermicide added. This may give some additional contraceptive protection. Vaginal spermicides may also be added before sexual intercourse.
Some condoms have lubricants added.
These do not improve birth control or STD protection. Condoms are available without a prescription. The Reality Female Condom was approved by FDA in April 1993. It consists of a lubricated polyurethane sheath with a flexible polyurethane ring on each end. One ring is inserted into the vagina much like a diaphragm, while the other remains outside, partially covering the labia.
