The sponge as a method of contraception has several benefits, one of which is the ability to be inserted up to six hours prior to sexual intercourse. This allows for greater flexibility and spontaneity for couples, as they do not need to time the insertion of the contraceptive device immediately before intercourse. It is designed to provide continuous protection against pregnancy during that duration, making it a convenient option for added sexual freedom.

The other options present characteristics that do not accurately describe the sponge. For instance, the sponge cannot be left in the vagina indefinitely; it is recommended to be removed after a maximum of 30 hours. It is also not a permanent method of contraception—as it is a barrier method that needs to be used with each sexual act. Furthermore, while cost is an important consideration, the sponge’s price may vary based on where it is purchased, but in many contexts, condoms can also be economical. Thus, the ability to insert the sponge up to six hours in advance stands out as a significant advantage.
