According to the United Nations Population Fund (UNFPA), an estimated 10.4 billion male condoms were used worldwide in 2005. It has been estimated that in 2015, nearly 18 billion condoms will be needed in low- and middle-income countries.
In Soviet gulags, condoms were used to smuggle alcohol into the camps by prisoners who worked outside.
Condoms can be used to hold water in emergency survival situations.
Condoms can be wrapped around a microphone to make underwater recordings.
But for all their glory, they can be tricky to use in the heat of the moment. They have a 15% failure fate with typical use. (2% with perfect use).
One problem commonly reported is placing the wrong side on the penis, and having subsequent difficult rolling the body down over the penis, because the roll is on the inside.
For even the most experienced and careful users, there can be breakages, splits, and slips.
The condom. A design classic, certainly. Functionality is testified to by billions of people each year.
But is it perfect? Not by a long way.
