Diaphragms

A diaphragm is a dome-shaped rubber disk with a flexible rim that fits inside the vagina and covers the cervix.

How does the diaphragm work?

The diaphragm blocks the sperm from reaching the egg. A spermicide is applied to the diaphragm before insertion. It is inserted before intercourse and left in place for at least six hours afterwards.

There is a 17% chance of pregnancy and the diaphragm does not protect against std's.

What are the side effects?

• irritation and allergic reactions
  
• urinary tract infections
  
• risk of toxic shock syndrome, a rare but serious infection
