What form of contraception can be purchased in stores, is pre-loaded with spermicide, and requires no prescription?

The correct answer is the contraceptive sponge. This form of contraception is available for purchase in stores and comes pre-loaded with spermicide, which helps reduce the chances of pregnancy by killing sperm or blocking their entry into the uterus. The sponge is designed to be inserted into the vagina before intercourse and can effectively provide protection for up to 24 hours, making it a convenient option for many users.

Additionally, one of the key advantages of the sponge is that it does not require a prescription, allowing for easy access compared to other contraceptive methods that may have more regulations or a need for a healthcare provider's assessment.

While other options like condoms do provide a barrier method and can be used with spermicide, they do not come pre-loaded with it. The diaphragm is also a barrier method but requires fitting and a prescription. Birth control pills, on the other hand, are hormonal contraceptives that need to be prescribed by a healthcare provider.
