Diaphragm with spermicide

Diaphragms are dome-shaped and fit into the vagina and over the cervix. They should be used with spermicide each time you have sex.

Diaphragms are made of flexible rubber or silicone and you need to insert them into the vagina every time you have sex in order to prevent pregnancy. They come in different sizes and will be fitted to suit you, so you need to get one fitted by a doctor or nurse before using it for the first time.

How does the diaphragm with spermicide work?

The Diaphragm stops sperm from entering the womb by covering the cervix. You need to use spermicide as well (a gel which kills sperm) to make sure no sperm survive. Between them, the diaphragm and the spermicide form an effective barrier. 

How do you use a diaphragm with spermicide?

You simply put the spermicide on the diaphragm and then place them inside the vagina to cover the cervix each time you have sex. You can put the diaphragm in a little time before you have sex but if you put it in more than three hours before you will need to use extra spermicide. 

What's good about the diaphragm with spermicide?

  • Can be put in before sex so it doesn't disturb the moment.
  • It's not affected by any medicines.
  • You and your partner can't feel it when you have sex.
  • It doesn't disturb your menstrual cycle. 

What do I need to watch out for with the diaphragm with spermicide?

  • The first fitting must be done by a trained doctor or nurse to make sure it's the right size.
  • It doesn't protect you against STIs - you'll need to use a condom.
  • It can take a little getting used to before you're confident using it. 

How effective is the diaphragm with spermicide?

92-96% effective if used properly. This means that between 4 and 8 women in every 100 who use the diaphragm will get pregnant each year. 

What makes the diaphragm with spermicide less effective?

You must leave it in for at least 6 hours after having sex. You'll need to use more spermicide if you have sex again, or if you have sex more than three hours after putting it in. 

Who can use the diaphragm with spermicide?

Diaphragms are suitable for most women. But some women can be allergic to rubber or spermicides or may have other conditions which prevent a diaphragm being used. Check with your doctor or nurse to see if a diaphragm with spermicide will suit you.
