Reply to comment by CanaryActive5296 in Why can we freeze embryos for IVF but not adult humans? What makes it possible for embryos? by Nimynn

I just watched a Tom Scott YT video about how microwaves were used in the 50s to reanimate frozen rats. Long story short, they were successful in reanimated fully frozen rats using microwaves...in the 1950s.

To somewhat answer your question though, it had to do with scale. They scientists who reanimated the rats found that it did not work on scale simply in laymans due to size.

He promised it was an interesting video and he delivered...

I read an article about this research. They tried to move up to slightly larger animals like rabbits, but their results because inconsistent. Small critters like mice and hamsters worked fine, though.
