NOTE ON MARIPOSA STUDY


The study did not take into consideration the other major factors resulting in failure: -

1) Shear failure. 2.2% to 3.2%

2). In shelf vulcanization failure. 0% to 100% depending on age, transport and storage conditions.

3). Incorrect use failures. Between 25% and 37% depending on which study you read.


Actual failure rate is the Mariposa transmission failure rate plus the above failure rates plus other factors not outlined above.

Reference for (2) above: - CONDOM CLIMATE CONTROL Condoms are sensitive to heat and cold, yet they are not normally transported in climate-controlled vehicles. Vesey, in his study ofcondoms,checked 72,000 trucks and has actual photographs of eggs frying in the backs of trucks used for condom distribution. Partly due to Vesey’s study, Burlington County, NJ, banned the distribution of condoms at the county’s AIDS counselling center, because they concluded that the risk of liability for condom failures was too great.

Reference for (3) above: - Reference for (1) above: - The more elastic condom broke less frequently (3.3 percent), compared to the "extra-strong" condom (4.3 percent), although the difference was not statistically significant.
