What Is the Birth Control Sponge?

The birth control sponge is a small, round device made of soft foam, infused with spermicide. It’s inserted deep into the vagina before intercourse to block sperm from entering the uterus and to kill sperm on contact.

So, what is the birth control sponge exactly? It’s a barrier method of contraception, meaning it physically prevents sperm from reaching the egg. It’s non-hormonal, making it ideal for women who are sensitive to hormonal birth control.

How Does a Birth Control Sponge Work?

Wondering how does a birth control sponge work? Here’s how:

The sponge covers the cervix to act as a physical barrier.
It contains spermicide (usually nonoxynol-9) that kills sperm.
It’s effective immediately after placement and lasts for up to 24 hours.
It must be left in place for at least 6 hours after intercourse.

Learning how to use a birth control sponge properly is crucial. Moisten it with water, squeeze it to activate the spermicide, and insert it deep into the vagina so it covers the cervix.

Birth Control Sponge Effectiveness

Birth control sponge effectiveness varies depending on whether a woman has given birth:

For women who have never given birth, the effectiveness is around 88-91% with typical use.
For women who have given birth, it’s slightly lower — around 76-80%.

While not as effective as some other methods, the sponge can be a reliable backup or short-term method for women who are not ready for more permanent solutions.
