- Birth control with spermicide is designed to kill the sperm before it reaches the egg and can even act as a sperm barrier depending on the type of spermicide you use.
- Depending on the spermicide option, the time frame in which they begin to work can vary. Contraceptive films can take up to 15 minutes to begin working, while spermicide foam can begin working immediately.
- Although all spermicides help to prevent pregnancies, they are not completely effective when used alone. Spermicides should always be used in conjunction with other contraceptives.
- Using spermicides with another form of contraception such as a condom, rather than alone, can prevent pregnancies 95 to 99 percent of the time.
- Allergic reactions in both men and women can occur with the use of spermicides and can cause sores or other wounds that make it easier to contract the HIV virus. Spermicide is not effective in preventing the spread of STD's.
