The diaphragm is a dome-shaped soft rubber device placed inside the vagina to cover the cervix before intercourse. It acts as a barrier to block sperms from entering the uterus. If properly used, the diaphragm will not be felt by the couple. Occasionally local allergic reactions to rubber or the chemicals can occur. Some women who use the diaphragm are more prone to bladder infections.

The doctor will determine which size is suitable for the woman by performing a pelvic examination. When using the diaphragm, spermicidal jelly is put on both sides of the rubber dome and around the rim (Diagram 1). The diaphragm is then inserted into the vagina using fingers or an inserter (Diagrams 2 & 3) so that the cervix is covered. It should not be removed until at least 6-8 hours after intercourse. It is then washed, wiped dry and kept in a clean container away from direct sunlight for use next time. The size and fit of the diaphragm should be checked during regular check-up. After giving birth or after any pelvic surgery, the woman should return to the clinic for examination to see if a diaphragm of a different size is needed.
