- A soft latex cup that covers the cervix. Plastic and silicone diaphragms may also be available.
- The rim contains a firm, flexible spring that keeps the diaphragm in place.
- Used with spermicidal cream, jelly, or foam to improve effectiveness.
- Most diaphragms come in different sizes and require fitting by a specifically trained provider. A one-size-fits-all diaphragm is becoming available. It does not require seeing a provider for fitting (see Question 9).
- Works by blocking sperm from entering the cervix; spermicide kills or disables sperm. Both keep sperm from meeting an egg.
