The Wide Seal diaphragm is made of silicone and has an inner rim, that holds the gel in place better. This also gives it a wider surface area and a seal against the vaginal wall. Suitable for those allergic to latex. The silicone diaphragm can be heated up in water, for example in the case of infections. Long shelf life.
The original, old-fashioned diaphragm was a rubber cap with a spring ring, comparable with a vaginal pessary. The diaphragm did not get ahead commercially in its country of origin however, but in the US. There Margaret Senger had already been vehemently fighting for birth control in the thirties. The diaphragm is still most popular there today. When the pill came onto the market in the sixties, the diaphragm and the condom were pushed from their top rank as contraceptives.
The diaphragm is as safe as a condom when used regularly and correctly.
Before you buy a diaphragm, a professionaly qualified person (such as a doctor, midwife, nurse or Pro Familia consultant) needs to test what diaphragm size is right for you ("fitting the diaphragm"). The application of a diaphragm is also usually practiced at this stage. After you have had an appointment like this, you can order the diaphragm with the appropriate size.
Always use a diaphragm together with a spermicide gel, such as the natural lactic acid gel
Contragel Green.
