Is castrating young boys ethical?

[TaraJo]

Haven't there been sex change operations though done to children? Why are they able to choose that but not this?

Yes, it can happen and it's rare but it's getting a bit more common. Kim Petras has made news as the youngest person to undergo sex reassignment surgery at 16, but there's a big difference between a 'sex change' and preservation of a singing voice. Probably the reason it's looked down on so much, from a medical perspective, is because the human body needs some kind of hormones to prevent osteoporosis. If you're transitioning, you just replace one hormone with another, but if you want to just be a boy without testosterone and you don't want to replace it with estrogen, your bones are going to get weak and brittle. We simply didn't know about the condition back then or the role hormones played in it. Now that we do, it can be more easily avoided.

If so, they are also unethical.

Children can't consent to such procedures.

I beg to differ. Big time. I've watched videos of parents describing their trans children's struggles and it's scary. I mean, if you have a child who is literally talking about suicide at 8 years old, and they're seriously thinking about it because that's how much they hate their gender, I don't want to be the one to tell them no.
