Cervical Cap (Barrier)Contraceptive Sponge
A contraceptive sponge is a soft round sponge filled with spermicide. You use it by inserting it into your vagina before intercourse. The sponge covers the cervix and blocks sperm from getting into the uterus and the spermicide kills sperm. You must leave the sponge in your vagina for 6-8 hours after ejaculation to ensure that all sperm are killed. Depending on the brand, the sponge is effective for 12- 24 hours after it is in place.The contraceptive sponge is 80-91% effective in preventing pregnancy (less for women who have previously had children).
Advantages:
- The sponge can be inserted several hours before having sex so that sexual activity is not disrupted
- You do not require a prescription to get the sponge. It can be purchased at pharmacies
- It is good for multiple ejaculations (as long as it is left in 6-8 hours after the last ejaculation to ensure that all of the sperm is killed)
- The package is discreet making it easy to carry in a purse or bag
Disadvantages:
- It’s possible to develop an irritation from the spermicides.
- If the sponge is left in too long there is a risk of developing Toxic Shock Syndrome (TSS) which can be very harmful if not treated
- It will not protect you against sexually transmitted infections (STIs) and the active ingredient in the spermicide (nonoxynol-9) can be irritating to the vaginal wall, thereby making you more susceptible to getting an STI
- If you are not comfortable putting things into your vagina, this may not be the best method for you.
Using the contraceptive sponge with a condom will increase the effectiveness for preventing pregnancy and will offer you STI protection as well.
There is currently no sponge available on the Canadian market. The distributer of the Today Sponge anticipates that it will be launched in Canada in 2010.
