Spermicide is a type of contraceptive that is used to kill or immobilize sperm to prevent them from reaching and fertilizing an egg. It comes in various forms, including creams, gels, foams, suppositories, and films, and is applied inside the vagina before sexual intercourse.
Spermicide works by using chemicals, such as nonoxynol-9, to destroy or weaken the cell membranes of sperm, making it difficult for them to move or penetrate the cervical mucus. Spermicide can be used alone, but it is more effective when used with other barrier methods of contraception, such as condoms or diaphragms.
Spermicide is readily available over-the-counter and is a relatively inexpensive and easy-to-use form of contraception. However, it is not as effective as other forms of contraception, such as hormonal methods like the pill or intrauterine devices (IUDs). Spermicide also does not protect against sexually transmitted infections (STIs), so it is important to use condoms in addition to spermicide if protection against STIs is also a concern.
It is important to read and follow the instructions carefully when using spermicide, as incorrect use can reduce its effectiveness. Some people may also experience irritation or allergic reactions to spermicide, so it is important to discuss any concerns with a healthcare provider.
