How does the contraceptive sponge work?
After the contraceptive sponge is placed in the vagina, it prevents pregnancy by releasing a spermicide called Nonoxynol-9. This spermicide works by killing or paralyzing sperm that comes into the vagina. A “dimple” on one side of the sponge fits over your cervix to form a barrier to sperm, preventing sperm from reaching an egg. The dimple also lowers the chances that the sponge will move out of place during sexual intercourse. The other side of the sponge has a loop for easy removal. There is only one size sponge.
Will my partner or I be able to feel the sponge?
The sponge is soft and once inserted properly you or your partner should not be able to feel it. If it feels uncomfortable, it may not be inserted the right way. If this happens, slowly and gently reposition the sponge deep into your vagina until it covers your cervix but be careful not to push your fingernail through it! You should be able to feel the loop.
How do I use the contraceptive sponge?
Wash your hands first. Remove the sponge from the package it comes in and wet it with two tablespoons of clean water. Squeeze the sponge once. This activates the spermicide. Next, insert the sponge into your vagina by sliding it along the back wall until it is up against your cervix. The dimple side of the sponge should face your cervix and the loop should face away from your cervix. Make sure that you feel the sponge covering your cervix. You can insert the sponge just before intercourse OR several hours ahead of time. You can have some protection against pregnancy for a total of 24 hours, no matter how many times you have sexual intercourse.
Leave the sponge inside of your vagina for at least 6 hours after you have finished having intercourse, but no more than a total of 30 hours. Before you remove the sponge, wash your hands and take hold of the loop on the sponge with one finger. Pull on the loop gently to remove the sponge. Make sure that the sponge is in one piece after you have removed it. Then throw it away. If it's torn, you should remove all the pieces from your vagina. If you have any concerns that the sponge isn't in one piece, contact your health care provider.
What about douching after intercourse?
Douching is not recommended after intercourse, and the American College of Obstetricians and Gynecologists recommends women not douche at all. Douching does not prevent pregnancy. There are no benefits and it is not safe because it can cause an increased risk in pelvic inflammatory disease, bacterial vaginosis (an infection of the vagina), and ectopic pregnancy (implantation of the fertilized egg outside of the uterus). Your body makes everything it needs to keep it clean. All you should be using to clean the outside of your vagina is water and soap. However, if you decide to douche in spite of this warning, you should wait at least 6 hours after intercourse so that the spermicide does not get washed away.
