Why it's done

Spermicide is a contraceptive that helps prevent pregnancy. Spermicide:

• Is most effective when used with a barrier method, such as a condom, diaphragm, contraceptive sponge or cervical cap
• Doesn't require you to rely on your partner for birth control
• Doesn't require a prescription
• Doesn't have the same side effects as hormone-based birth control methods
• Increases lubrication during sex

Your health care provider may discourage use of spermicide if:

• You're at high risk of contracting HIV, or you have HIV or AIDS
• You have frequent urinary tract infections
• You're at high risk of pregnancy — you're younger than age 30 or you have sex three or more times a week
• You're not likely to consistently use spermicide along with other barrier methods

Vaginal pH regulator gel (Phexxi) also helps prevent pregnancy. It provides a nonhormonal option for birth control to be used right before you have sex.
