Sponge

The sponge is a round piece of white plastic foam. It has a dimple on one side and a nylon loop across the top. It is 5 cm across, and you insert it in your vagina before you have sex. The sponge works in two ways: it keeps sperm from getting into your uterus by blocking your cervix, and also continuously releases spermicide.

Quick facts:

  • No hormones.No prescription.
  • You can insert it up to 24 hours before sex.
  • Effectiveness: the sponge is not the most effective method, especially if you have already had a kid.
    • Perfect use:

      80-91%

    • Typical use:

      76-88%

  • Side effects: you may have some irritation
  • Effort: high – you have to put it in every time you have sex

Good option if you do not mind getting pregnant. Most people do not use the sponge correctly, so women often wind up pregnant. If you do not want to get pregnant or have a baby, think about using a different method.

You are comfortable with your body. If you are not okay with putting your fingers inside yourself, the sponge is not the best option for you. It is a lot like putting in a tampon, though: if you can do that, you can probably manage the sponge.

It takes discipline. You have to remember to insert the sponge each and every time you have sex. You will need a bit of self-discipline and planning. But at least you can carry it with you if you want.

Allergies? You should not use the sponge if you are allergic to sulfa drugs, polyurethane, or spermicide.

The pregnancy question. The sponge has no hormones, so you will be able to get pregnant as soon as you stop using the sponge. Protect yourself with another method if you stop using the sponge and do not want to get pregnant.

You can insert the sponge up to 24 hours before you have sex. It does take a bit of practice to put it in correctly, so follow these instructions.

How to put it in:

  1. Wash your hands with soap and water. Let them air dry.
  2. Wet the sponge with at least 30 mL of clean water before you put it in.
  3. Activate the spermicide by giving the sponge a gentle squeeze.
  4. With the dimple side facing up, fold the sponge in half upward.
  5. Slide the sponge as far into your vagina as your fingers will reach.
  6. The sponge will unfold on its own and cover your cervix when you let go.
  7. Slide your finger around the edge of the sponge to make sure it is in place. You should be able to feel the nylon loop on the bottom of the sponge.
  8. You should only insert the sponge once. Do not reuse a sponge that you have already had inside you. When it is in, you can have sex as many times as you want.
  9. You are ready to have sex once it is in.

How to take it out:

  1. Leave it in for at least six hours after sex.
  2. Wash your hands with soap and water.
  3. Put a finger inside your vagina and feel for the loop.
  4. Once you have the loop, pull the sponge out slowly and gently.
  5. Throw the sponge away in the trash. Keep it away from children and animals.

Tips and tricks

The sponge needs to be completely wet to activate the spermicide. Make sure to squeeze it to distribute the water.
