Spermicidal creams are a type of contraceptive cream designed to kill or immobilize sperm, preventing fertilization. While the term "spermicidal cream" may be the most common description, there are various synonyms and alternative names used for this type of product. Some of these include spermicidal gel, contraceptive foam, vaginal films, spermicide tablets, and vaginal suppositories. Spermicidal creams are usually inserted into the vagina before sexual intercourse, and they are generally effective when used consistently and correctly. It's important to note that spermicidal creams should not be used alone but combined with barrier methods such as condoms for optimal protection against unintended pregnancy.
