Cervical cap and diaphragm

• The cervical cap and diaphragm are two types of barrier   contraception, which prevent the sperm entering the cervix.   Both devices are reliable forms of contraception when used   with a spermicide.

• The initial fitting is carried out by a trained family planning   nurse, who will also give instruction on how to use the device.

• Correct insertion is important. The cap should lie directly over   the cervical opening, and the diaphragm across the top of the   vagina and over the cervical opening.

• Women using the cervical cap must examine themselves   before insertion to establish the position of the cervix. It is   important to be aware that cervical position may alter at   certain times of the month and throughout life.

• Both the cervical cap and the diaphragm should be left in   position for 6 hours after intercourse to ensure that sperm   
  that remain in the vagina do not enter the uterine cavity.

• The cervical cap and diaphragm must be refitted after   pregnancy, and after a significant change in weight,
  because your anatomy can alter.
