The Contraceptive sponge is a soft, donut-shaped, disposable birth control device that is placed in the vagina, against the cervix. It is 86%-90% effective in preventing pregnancy, if used correctly.
 

IT WORKS IN THREE WAYS:

  • blocks the opening of the cervix so sperm can't pass through
  • it traps/absorbs sperm
  • it continually releases spermicide to kill sperm

CONTRADICATIONS:

ADVANTAGES:

  • one size fits all
  • may offer protection against STD's from the spermicide
  • it can be inserted hours before intercourse, and remains effective up to 24 hours, even after repeated intercourse

DISADVANTAGES:

  • may be difficult inserting and removing--requires PRACTICE
  • may cause itching/irritation
  • may increase the incidences of yeast infections
  • must remain a full six hours after intercourse to ensure all sperm are dead
  • can fall out while straining abdominal muscles ie. exercising, having a bowel movement
  • can tear upon removal
  • cannot be used while menstruating
  • can cause the following side effects:
  •  fever
  • vomiting
  • diarrhea
  • muscle pain/dizziness
  • rashes (look like a sunburn)

INSERTING THE SPONGE:

  • check expiry date and tear open the package carefully
  • wash hands with soap and water
  • remove sponge from the aluminum cup and grasp it by inserting the index finger into  the slot between the two circular sections
  • squat with legs apart or raise one leg
  • insert 1 or 2 fingers into the vagina and locate the cervix (feels like tip of nose)
  • slide sponge into vagina as far as it will go
  • make sure sponge is covering the cervix with the moistened side being inserted into the vagina first

REMOVING THE SPONGE:

  • wait six hours after intercourse before removal
  • insert finger into vagina and find the two sections. Bear down as if having a bowel movement to find it
  • slowly and gently pull out the sponge by gripping both the inner and outer parts
  • examine sponge to make sure all parts have been removed
  • dispose of the sponge
  • NEVER RE-USE THE SPONGE, ONCE IT HAS BEEN REMOVED FROM VAGINA.
  • If you have difficulty in removing the sponge, contact a doctor or birth control clinic for assistance.
