What is a diaphragm?
A diaphragm is a rubber disk that you put into your vagina to cover your cervix
. A diaphragm works by blocking the sperm
from swimming up your vagina. When the diaphragm is in place, the sperm stay put. They can't enter your cervix or reach the egg to fertilize it and get you pregnant

How does a diaphragm work?
A diaphragm is shaped like a dome. It's made from thin rubber that's attached to a metal ring. The diaphragm's ring is really bendable and the rubber is soft, so you can fold the whole thing in half to get it inside your vagina. The ring is important because it holds the diaphragm in place in your vagina and blocks the entrance to your cervix

Where can I get a diaphragm?
There are different types of diaphragms, and they come in different sizes. Your health professional will measure you for a diaphragm that's the right size for your body. Then you'll get a prescription that you can get filled at the drugstore.
The type and size of diaphragm that's right for you can change if you have a baby or if you gain or lose a lot of weight. If you're using a diaphragm and either of these things happens to you, ask your health professional to measure you for a new diaphragm. back to top
What does a diaphragm feel like?
Your diaphragm should fit snugly around your cervix and shouldn't bother you. Usually, once it's in, you can't feel it at all. back to top
How reliable is a diaphragm?
The diaphragm is supposed to be 94% effective in keeping you from getting pregnant when it's used the right way. This makes it more effective than condoms
and spermicide, but less effective than birth control pills
. In real life, the diaphragm is only 82% effective. That's because many girls don't put their diaphragms in every time they have sex. And sometimes girls put the diaphragm in the wrong way. If it doesn't cover your cervix completely, it won't work, because the sperm won't be blocked completely. back to top
How do you put in a diaphragm?

How do I know if the diaphragm is in the right way?
- Cover each side of the diaphragm with spermicidal jelly. This is a clear gel that kills sperm on contact. You can buy it at the drugstore in the same area where the condoms are sold.
- Press the sides of the metal ring together to fold it, so that you can fit it into your vagina. It may be slippery from the spermicide, so get a good grip.
- Squat down or place one foot on the toilet or the bathtub. Push the diaphragm into your vagina. Once it's in the right place, it pops back to its regular size to cover your cervix.
- Make sure that the diaphragm is in the right position by putting your finger into your vagina. When you feel around, make sure the diaphragm has completely unfolded. It should cover your cervix and fit snugly in your vagina.
If you decide a diaphragm is the right kind of birth control for you, practice putting it in until you're sure you can put it in correctly. At your appointment, have your health professional check to make sure you put it in right and can take it out without any problem.
You have to put your diaphragm in the right way so it can do its job of blocking off your cervix and blocking the sperm. You can only tell that it's covering your cervix if you know where your cervix is. Before you put your diaphragm in, put your index and middle finger up your vagina to feel where your cervix is. It will feel like the tip of your nose sticking out into your vagina and is about the size of a quarter.
When you put your diaphragm in, put your fingers into your vagina again to be sure that it's in there correctly. If the diaphragm is covering your cervix, you've done it right. back to top
How do I take a diaphragm out?
First, make sure you've had the diaphragm in your vagina for at least 6 hours. Don't take it out early! If you do, the sperm could still be alive and you could get pregnant!
If you're ready to take out your diaphragm, here's what to do:
What do I do with the diaphragm after I take it out?
- Put your index and middle fingers into your vagina and grab hold of the ring of the diaphragm.
- Pull out the diaphragm. It will fold in half as you pull. back to top
After you remove your diaphragm, clean it and put it away until you need it again. Every now and then you should check your diaphragm for any damage. Look at it closely to be sure it doesn't have any holes or tears. Also fill it with water. If it leaks, it probably has a hole. If you find a hole or tear, you should throw the diaphragm away and get a prescription from your health professional for a new one. back to top
Can a diaphragm cause problems?
Some girls can get a skin irritation from the spermicidal jelly. Some girls also get more urinary tract infections
when using a diaphragm for birth control. That's because the diaphragm can press on the urethra
, the tube that leads from the bladder
to the outside of the body. back to top
