What is the diaphragm?
A diaphragm is a shallow, cup-shape made of silicone. In Australia there is one size diaphragm available sold as Caya®. It is used with a special gel (jelly-like material, sold as Caya Gel®).
How effective is the diaphragm?
If used correctly, every time you have sex, it is 86% effective at preventing pregnancy. If used incorrectly, for example not inserting properly before sex or removing too soon after sex, it might only be 82% effective.
What stops the diaphragm from working?
The diaphragm might not work if it is:
- Not inserted correctly
- Used without the gel
- Taken out less than six hours after sex
- It’s past its use by date
How do I use the diaphragm?
A teaspoon of gel is placed in the cup of the diaphragm. You then put the diaphragm inside the vagina so it covers the cervix (opening to the uterus/womb).
The diaphragm may be inserted up to two hours before having sex. It must stay in place for at least 6 hours after sex. It should stay in place for a maximum of 24 hours.
Before you use it, you can ask a doctor or nurse to check that the diaphragm fits well and that you are inserting it correctly. The diaphragm is the wrong shape for about 1 in 7 women. The doctor or nurse can provide advice about how to insert the diaphragm comfortably. You can watch a video with instructions from the Caya® website http://www.caya.eu/en
How does the diaphragm work?
The diaphragm and gel work as a barrier to prevent sperm from passing through the cervix into the uterus. The sperm die off quickly in the vagina.
Where can I get the diaphragm?
You can buy the diaphragm from some pharmacies/chemists, family planning clinics and online.
What is good about the diaphragm?
- You can insert it hours before having sex
- It has little or no side effects
- You can buy it without a script
- It is a choice for those who do not want to use hormonal contraception
Are there any side effects from using the diaphragm?
Possible side effects for a small number of users can include:
- Irritation of the vagina or penis
- Increased risk of bladder infection
Can the diaphragm cause any serious health problems?
The diaphragm might cause a very rare blood infection called toxic shock.
Reasons why the diaphragm might not be a good option for you:
- Are prone to bladder infections
- Are within 6 weeks after giving birth
- Are unable to feel if your cervix is correctly covered by the diaphragm. Speak to a doctor or nurse for advice
What if I forget to use the diaphragm?
You may need emergency contraception if you had sex without using the diaphragm and did not use other contraception (check with your doctor, nurse or pharmacist).
What happens if I get pregnant while I’m using the diaphragm?
It is safe to continue the pregnancy (and stop using the diaphragm) or to have an abortion.
Can I use the diaphragm after I’ve had a baby?
You should usually wait six weeks after having a baby to start using the diaphragm.
