can make sense, but in in practice
The results just have been unconvincing, unfortunately.
Really out of all of these, the PGTA is the only one I was really familiar with.
I did have this done my and it was presented as just optional, like a similar thing to NIPT, but getting it before before embryo transfer.
But we know from prior studies that the testing methods themselves are far from perfect and they are not always identifying the truly aneuplate embryos.
And I think we could go much further into this.
There I think there's some nuance, but the there's a really good summary about it.
In the ASRM committee opinion on PGTA, that that's from twenty twenty four and we can link to that.
For example, they list some studies where if they're looking at advanced maternal age patients with higher baseline rates of aneuploidy.
They may have higher life birth rates if they do this, but
But overall even they conclude the ASRM that it it's definitely
not at the point of being a universal recommendation.
And then for those other IVF service add-ons, either the theories themselves are just not even true, or maybe the theories are onto something, but the methods need work or some combination.
Well, the other things they looked at don't even seem to have quality studies at all, let alone convincing evidence of benefit.
There there are a lot of lower quality studies, for example, with acupuncture.
But no no positive
No positive evidence.
The intralipid infusion that's given IV, which is also thought to reduce not inflammation, but reduce natural killer cell.
activity and other immune cells in the endometrium also has no evidence.
The PIXI, I also hadn't heard of, but it's a technique that is used to select sperm based on their ability to bind to hyaluronic acid.
