Diaphragm
What is a Diaphragm?
How to use a Diaphragm
A diaphragm is a dome-shaped rubber
(latex) cup with a flexible rim. It is a
barrier method of birth control and is
placed into the vagina covering the
cervix. A diaphragm helps prevent
pregnancy, but does not protect against Sexually Transmitted
Infections (STIs)
It is important to feel comfortable putting your diaphragm
in. You can practice to make sure you are putting it in right.
If you are not sure about the proper fit, see your doctor or a
nurse practioner with the diaphragm already in place. That
way you can be sure your insertion technique is correct.
How does the Diaphragm work?
A diaphragm has to be used with spermicidal jelly or cream,
which kills sperm. The diaphragm holds the jelly or cream
close to the cervix, the opening to the uterus. It stops sperm
from going into the cervix.
If you are allergic to latex or spermicide, the diaphragm is
NOT a choice for you.

Where to get a Diaphragm
A diaphragm must be fitted by a doctor or trained medical
person (i.e. nurse practitioner). Diaphragms are available in
various sizes. Once the diaphragm has been properly fitted,
a prescription will be given to you. This prescription can be
taken to any pharmacy. Talk to your doctor or visit the Sexual
Health Clinic at Public Health for more information.
Inserting a Diaphragm
• You may find insertion easier
if you empty your bladder
• Wash your hands with soap
and water
• Check that you have all your
supplies ready. You need
spermicidal jelly or cream, a
plastic applicator for inserting additional spermicide and a
diaphragm
• Always check your diaphragm for holes, cracks or tears by holding it up to the light
• The diaphragm can be inserted just before intercourse or
up to six hours ahead
• Apply spermicidal jelly or cream inside the diaphragm by
holding it with the dome down. Apply approximately one
teaspoon into the dome. Spread it around the sides and
rim of the diaphragm
• Hold the diaphragm with the dome down and squeeze it
gently so the diaphragm folds. Both sides of the rim should
touch
• Spread the opening of your vagina with your other hand and insert the folded diaphragm into your vagina. The
leading edge of the diaphragm will fit snugly behind the cervix. The front rim will fit against the pubic bone

• Once in place, you should not be able to feel the
diaphragm. If it is uncomfortable, the diaphragm may not
be in the correct position. Take it out and try again
• Check with your fingers to make sure that the diaphragm is
covering the cervix before sex
Side Effects of a Diaphragm
Removal of Diaphragm
• High fever
• Dizziness, faintness, weakness
• Sore throat, aching muscles and joints
• Once intercourse has occurred, you must leave the
diaphragm in place for 6–8 hours. Do not douche during
this time. If you have intercourse again within this time,
use an applicator to place an extra dose of jelly/cream in
front of the diaphragm
• When it is time to remove, locate the front rim of the
diaphragm with your finger
• Hook your finger over the rim or behind it, then pull the
diaphragm down and out
Care of Diaphragm
• Wash your diaphragm and applicator after each use.
Plain soap and water is best. Dry it well and place it in its
protective case
• Do not use oil-based products with your diaphragm as
these will damage it
• Check your diaphragm every year to make sure that it is still the correct size for you
• A diaphragm must be refitted after pregnancy, pelvic surgery, an abortion, weight gain or loss of ten pounds or more
• Replace your diaphragm every two years
If used properly, there are no side effects from a diaphragm.
Do not leave your diaphragm in longer than 24 hours because
of the possible risks of toxic shock syndrome (TSS). Toxic
Shock Syndrome danger signs:
Remember!
• Practice using the diaphragm correctly
• A diaphragm is not an effective tool to protect against
Sexually Transmitted Infections (STIs)
• Your best protection is to use a diaphragm with a
condom
• Talk to your health care professional to see if a
diaphragm is right for you
