I can get the implant done at my GPs these days, but not every GP does it so I guess sometimes you have to either travel to a clinic or have something else (in Cambridge by "travel" I mean "cycle to Addies" but if you live more rurally the journey could be very long!)

The Indians seemed to have some sort of reversible thing for men too which looked interesting. India! clearly a hotbed of contraceptive research; v important to do research.
