What it does: Made of rubber and shaped like a dome, a diaphragm prevents sperm from fertilizing an egg. It covers the cervix and must always be used with a spermicide. Women must be fitted for a diaphragm in their doctor's office.
Who should avoid it: If your weight tends to fluctuate by more than 10 pounds at a time, the diaphragm may not work. If you gain or lose weight, you'll need to be refitted. Prone to bladder infections? You might want to consider another option. If you've had toxic shock syndrome, you shouldn't use a diaphragm.
