Some food for thought:
"A German scientific research institute has warned that most condoms on the market contain a cancer-causing chemical and has urged that their manufacture be subjected to stringent quality control.
Sobering news for rubber contraceptive users.
The Chemical and Veterinary Investigation Institute in Stuttgart said on Friday it had found the carcinogen N-Nitrosamine in 29 of 32 types of condoms it tested in simulated conditions.
The condoms, which were kept in a solution with artificial sweat, exuded huge amounts of cancer-causing N-Nitrosamine from its rubber coating. Researchers measured amounts of N-Nitrosamine, that were way above the prescribed limits for other rubber products such as baby pacifiers."
