Diaphragm

What is a diaphragm?

A diaphragm is a round piece of flexible rubber with a rigid rim. Before intercourse, the diaphragm is placed in the vagina covering the cervix. The diaphragm prevents semen from entering the womb. Spermicide should always be used with a diaphragm.

How effective is a diaphragm?

With the use of a spermicide the diaphragm is 92-96% effective.

How do I use a diaphragm?

Spermicide should be put in and around the rim of the diaphragm no more than two hours before intercourse. The diaphragm is then inserted into the vagina. More spermicide should be inserted into the vagina each time you have sex. Do not remove the diaphragm for at least six hours after intercourse and do not leave the diaphragm in place for more than the recommended time of the specific product

Where do I get a diaphragm?

You can get replacement diaphragms from your GP, family planning clinic or local pharmacy. For your first diaphragm, your doctor or nurse will give you a pelvic examination first so that you receive a diaphragm that fits properly. You may need to have a different size diaphragm if you lose or gain more than 3kg in weight.

Does a diaphragm protect against sexually transmitted infections?

No. Using a diaphragm and spermicide may not protect against some STIs, including HIV (the virus that causes AIDS). The male condom provides the best protection from most STIs.
