What are vaginal diaphragms?
The diaphragm is a thin rubber dome with a circular spring around its edge, and is placed in the vagina to prevent pregnancy. Normally after vaginal sex some sperm enters the uterus through the cervix to go along the tubes to where the egg is fertilised. A diaphragm prevents sperm from entering the cervix. There are several different sizes of diaphragms and it is necessary for you to be fitted with the right size. The great advantage of the diaphragm is it is virtually free of side effects, need only be used when needed, does not necessarily require partner co-operation and can be inserted well before intercourse begins. A pregnancy rate of 2 to 4 percent can be expected with a diaphragm but it can only be effective if it is used every time.
