Spermicide

Spermicide is a type of contraceptive that kills sperm or stops it from moving. Spermicides are available in several forms, including cream, gel, foam, film, and suppositories. Most spermicides contain nonoxynol-9, a chemical that kills sperm.

Usage

Spermicides are used alone or with other methods of birth control. They are placed deep inside the vagina shortly before sexual intercourse. Spermicides work immediately and do not have to be in place for any certain amount of time after intercourse.

Effectiveness

The effectiveness of spermicides for pregnancy prevention varies widely, from a 6% failure rate with perfect use to a 26% failure rate with typical use.

Side Effects

Some people may have an allergic reaction to spermicides, which can cause itching, redness, and swelling in the genital area. Frequent use of spermicides may also increase the risk of getting HIV and other sexually transmitted infections.
