What is the effectiveness rate of the contraceptive sponge?

The contraceptive sponge has an effectiveness rate of approximately 76-88% when used correctly, making this range the most accurate representation of its reliability as a form of contraception. This means that when individuals use the sponge according to the instructions, they have a 76-88% chance of preventing pregnancy during a single act of intercourse.

The effectiveness can vary depending on whether the user has previously given birth; it tends to be higher for women who have not given birth. When considering birth control methods, understanding their effectiveness is crucial for making informed choices about sexual health. While other options may present lower effectiveness rates, they do not accurately capture the sponge's reliability when used properly.
