Copper IUDs are non-hormonal, so they don't affect libido through hormonal cycling in that way. They tend to lead to longer and heavier periods which could affect libido to some extent, but it's not the same thing you're describing. For the same reason they also don't affect muscle and fat gain...
Uh, yeah, that's true, but it's not the author talking, it's Hiro, he's comparing with what he knows 100 yen to be worth in the time he came from. It'd make little narrative sense for the character to go out of his way to point out to himself exactly what 100 yen can buy, he already knows that...
