Spermicide is a contraceptive substance that destroys sperm, preventing pregnancy. It usually comes in the form of creams, gels, or foams. Think of it as a chemical barrier that stops sperm from reaching an egg. It's often used in combination with other birth control methods for increased effectiveness. Spermicides are a relatively simple, over-the-counter option, but not the most reliable on their own. They work by disrupting the sperm's cell membrane. It's like a shield that weakens the sperm's ability to fertilize.
