Most spermicides have an unpleasant taste but will not usually harm you or make you feel ill, however it is advisable to avoid swallowing excessive amounts. If you are concerned about feeling ill following swallowing some spermicide, you should seek the advice of a healthcare professional.
Spermicides contain substances that kill sperm. Some products also form a thick foam or mucus which acts as a barrier against the sperm entering the womb where it could fertilise the egg. They can come in the form of foam, foaming tablets, pessaries, creams, jellies and sponges. Spermicides are not effective enough when used alone, and should be used in combination with barrier methods such as the diaphragm or cap.
A pelvic examination by either a physician or a skilled healthcare professional is required for fitting diaphragms. Fitting rings are produced by diaphragm manufacturers in various sizes and with different rim types. Sizes range from 50 to 405 mm. They are most commonly available in flat spring or coil spring rim types. Diaphragms between 60 -85 mm in diameter will provide the correct fit for most women. Initially the fitting ring size is estimated by clinical assessment of the vaginal length. Smaller or larger sizes are then inserted until the correct fit is achieved. It is important that each individual is fitted with the type of rim that she will ultimately use as the rim type can affect fit and ease of insertion. It should fit snugly into the upper half of the vagina. The user should practice insertion under supervision and placement should be inspected to ensure that the fitting ring is correctly positioned in the vagina. Fitting is best done when the bladder is not empty so that the user can test to ensure that urination is easily accomplished with the selected fitting ring in place. The diaphragm may require resizing following a full-term pregnancy, pelvic surgery, or abortion, or if there is a major change in weight.
There is no reason for the diaphragm to get lost or stuck inside your body. A diaphragm will be specifically fitted by a healthcare professional to ensure it fits and can be used effectively by you. If you are having a diaphragm fitted, you should practice insertion, placement and removal with the healthcare professional. The diaphragm should also be checked every six months by a healthcare professional to make sure it still fits properly.
A diaphragm should be removed no sooner than 6 hours after intercourse and can be left in place for up to 24 hours after intercourse. Additional spermicide is required with subsequent acts of intercourse. If more spermicide is required it should be placed in the vagina and the diaphragm should be left in place.
The diaphragm can be inserted immediately before or up to 6 hours before intercourse. Some people do find that this might interfere with spontaneity.
