What is it?

A contraceptive sponge is barrier method of birth control that contains spermicide.  It is disposable (you throw it away), and used only when planning on having sexual intercourse (sex).

 How does it work?

The sponge fits over the cervix and absorbs sperm, preventing it from entering the uterus (where pregnancy occurs).  The sperm is killed by the spermicide in the sponge. 

Remember, the Contraceptive Sponge protects against pregnancy but it DOES NOT protect you from all Sexually Transmitted Infections (STIs) (e.g. HIV)

How effective is it?

The Contraceptive Sponge is 78% effective in preventing pregnancy

Possible Side Effects

• The spermicide within the sponge may cause vaginal irritation
• The sponge may cause vaginal yeast or bacterial infections
• The sponge may produce an odour once mixed with bodily fluid
• Allergic reaction to the chemical in spermicide (nonoxynol-9) or polyurethane (sponge material)

 The sponge is a good choice for you, IF:

• You prefer a non-hormonal type of birth control

The sponge is not for you, IF:

• You are menstruating (having your period)
• You have a history of Toxic Shock Syndrome
• You are uncomfortable with inserting and removing the sponge

Important points

• Never reuse a sponge

• You do not have to change the sponge if intercourse (sex) is repeated within 12 hours of its insertion
• The contraceptive sponge should not be removed sooner than 6 hours after having sex and should not stay in for longer than 12 hours.
• Contraceptive sponges are available without a prescription in drugstores and at the Health Unit
