What is it?
A silicone dome that covers the cervix (the area at the top of the vagina) and prevents sperm from getting inside. You insert the diaphragm into the vagina. When it is in place, it covers the cervix. The diaphragm should always be used in combination with a lactic acid gel designed for use with diaphragms, such as the Caya gel or Contragel. The diaphragm is reusable and generally lasts about a year.
How do you use it?
Start put placing lactic acid gel inside the dome shape of the diaphragm. Holding the diaphragm so that the curve of the down faces downwards, squeeze the rim of the diaphragm until the sides touch together. Insert the diaphragm into the vagina as far up as possible, so that it covers the cervix. After vaginal sex, leave the diaphragm in for at least 6 hours.
Where can you get it?
You can get a one-size-fits-most diaphragm called Caya at some pharmacies without a prescription. Planned Parenthood Ottawa has a list of pharmacies that carry diaphragms. Pharmacies that carry the Caya diaphragm should also have lactic acid gel in stock.
How much does it cost?
Diaphragms average from $75 – $100. Lactic acid gel designed for use with diaphragms costs about $30.
How effective is it?
When used with spermicide, the diaphragm is 81% with typical use.
Does it reduce the risk of STIs?
