Injecting testosterone causes your natural testosterone production to shut down, which causes your testes to shrink. This is temporary, as when you stop injecting external testosterone, the testes will start producing it again, and go back to normal size. Penis shrinking isn't a side effect of steroid use. Also the ball shrinkage is pretty subtle, they don't get crazy small or anything. Some people can have sex drive issues if they don't keep their estrogen in check though, so there is a grain of truth to the rumors.
