Caya® diaphragm and Caya® Gel
Caya® offers triple safety
- The silicone membrane acts as a mechanical barrier immediatley in front of the cervix. The solid rim of the Caya® safely covers the cervix.
- Caya®Gel forms, by means of the cellulose (gel-forming agent), an additional physical barrier in front of the cervix.
Caya® Gel has an acidic pH value of 3.8, which deactivates sperm cells. At the same time, this pH value has a positive effect on the vaginal fluid and offers protection from vaginal infections.
Caya® -Safety, ease of use and comfort have been proven in clinical studies.
The innovative form and function of Caya® were studied and tested in several independent studies1–4 in the US.
In a multicentric clinical trial by CONRAD4 (www.conrad.org), at 10 centres in the US the reliability was examined: In 450 couples, the risk of pregnancy, safety, acceptance of the contraception method and fit were tested.
In case of correct application of the Caya® diaphragm the 12-month risk of pregnancy was found to amount to 13.7 %. This value is not the Pearl Index which defines method safety determined in the long term of use (cf. http://en.wikipedia.org/wiki/Pearl_Index).
The Pearl Index for diaphragms is comparable to that of natural rubber latex condoms for males.
