I don't care. People can do whatever they want, but personally I could not understand what is the point of choosing the sex through the whole genetics thing, unless you live under some hard patriarchal society and you need a boy in the family. Which is not the case of Denmark and England*. And then probably it would be a better idea to change patriarchal regime before the sex of the child.

*Well, most developed nations where feminist movements have sprouted are less patriarchal, but I think most countries still have a way to go in their mindset to be actually considered equitative.
