The best birth control ever

I think I'd rather just have the responsibility of birth control..y'know since guys don't have to worry about a baby growing inside them >_>

"Ye girl I got the needle, don't worry about it!"

[INDENT]I'm a bit skeptical of claims of "100% effectiveness", especially of something that's supposed to somehow wear off over time. At 9.5 years it's 100% effective, but at 10 years it's not? Regardless of conditions like temperature, pressure, or, umm, frequency of use?
Such a nice round number, 10 years...

Anyway, I wish them luck with the research. [/INDENT]

Typically for these types of procedures they tell you to refresh it when it starts to become ineffective, which on average is 10 years.
