Caps and diaphragms
A diaphragm (or cap) is a soft, silicone dome that covers the cervix (the entrance to the uterus). If used properly, it is just as reliable as other contraceptives.
How does it work?
You insert the diaphragm into your vagina, no more than 2 hours before you have sex. First, you put some spermicide on the diaphragm. Then you slide it into your vagina, just like a tampon. After sex, leave the diaphragm in for at least 6 hours.
Using it again
When you take it out of your vagina, rinse the diaphragm well with lukewarm water to clean it. Now it is ready to use again. You can use the same diaphragm for up to 2 years. It doesn’t protect against STIs.
Where can you get a diaphragm or cap?
Talk with your doctor about how and if you can get a diaphragm. They can also be purchased online, these come in different sizes, speak to your doctor to find out which size best works for you, your doctor can also fit it in for you.
What you need to do
- Practice a couple of times with inserting your diaphragm. Practice makes perfect!
- Not sure if it fits properly? Have it checked by your doctor.
- Do you use a lubricant during sex? Then choose a water-based one. Other types of lubricants could damage the diaphragm!
- Check the diaphragm for any damage as you are rinsing it under the tap.

When do you run the risk of pregnancy?
