The only reason he survived in the ice was the serum (and his close to zero metabolism) There's a saying that 'people aren't dead, til they're warm and dead.' He de-aged when he was shot and 'killed' in CA#25 (2012) I believe. My guess is, as with previous storylines where he's lost the serum, he ages until he gets a transfusion from someone with the serum, like the kid from Young Avengers with a copy of Cap's or Isiah Bradley's shield, but I did read somewhere that the serum is basically a part of his body, that it's been absorbed - that it can't be 'taken' from him anymore, his body will continue to make more, but I'm sure others can correct me on these points.
