Pre-selecting for preferred gender

[RZehr]

So the only way you could do this is through a fertility clinic using IVF?

I expect that a very tiny percentage of people who don't need to use IVF would chose to go through the hassle and expense just to increase the chance of one sex or the other.

BTW, I read somewhere a statistically significant higher number of youngest children are boys rather than girls. Apparently it is not uncommon (especially in the past) to keep having kids until you finally get a boy.

To clarify, I don't know that it has been used in humans. So I don't know what the mechanics of it would look like. It says they've attained a 90% success rate on the gender.
I'm more interested in the ethical aspect than I am the mechanical aspect.

Reading through the description it sounds like a LOT more embryos would be destroyed using this method than through regular IVF. But maybe I'm not understanding the description of the process.

Where are you getting this? I don't think any embryos are being destroyed at all. I don't see anything about IVF.
The part of the article I quoted, and the way I understand the technology, is that the sorting is being done on the bull semen prior to fertilization. Then the cow is being impregnated with semen that has had all the Y chromosomes removed, leaving only the X. No IVF, just artificial insemination, which has been used in animals for a while. As long as the sorting process is perfect, this leaves only the possibility that the embryo has XX and not YX.

^^correct. AI / artificial insemination.
as well, i corrected my post above about the Angus beef farm. it was not IVF.

If this works on humans would it be desirable in cultures like China where females are routinely aborted in favor of a male child.

Yes, it seems bad, but better than abortion.

I feel like this wouldn’t work for multiple reasons… one being that it would have to be mechanically delivered would be one… this isn’t usually as effective and then IVF tends to be the primary way. I vaguely think there was something about sex selection but I’d have to look it up again.

abortion industry profiteers would not want to lose human tissue+body parts.

Maybe I misread the description.

Are they applying their x chromosome sorting method to sperm or to embryos?

[RZehr]

Sperm only.

And better than the post-birth selecting described in Exodus 1.
