The UK's IVF system has been exploited by couples to gain insight into their embryos' potential intelligence quotient, height, and other physical traits. The practice, known as polygenic embryo screening or PGT-P, is not currently permitted under the regulations governing fertility treatments.
Polygenic testing in embryos is possible through the analysis of genetic data, including genome sequencing, which can reveal sex and provide predictions for various traits. However, this technology faces controversy due to concerns over accuracy and the ethics of using such information to guide reproductive decisions.
Complex traits like intelligence are influenced by multiple genes with differing effects, making it difficult to predict an embryo's likelihood of developing certain conditions. The algorithms used in polygenic testing rely on vast genetic databases but offer probabilistic predictions rather than certainties.
Some advocate for PGT-P, citing potential health benefits and a parent's right to make informed choices about their child's genetics. Nevertheless, experts emphasize the need for further research into the accuracy of these tests within the context of embryo selection.
Regulatory bodies have expressed concerns that using such technology without thorough validation may lead to premature adoption of untested methods. As genetic sequencing becomes more accessible, it is essential to address these issues and establish clear guidelines for its use in fertility treatments.
Critics argue that polygenic scores are overly simplistic, capturing only a small fraction of the complex genetic factors influencing traits like intelligence. By adopting PGT-P without rigorous testing, parents may be subjecting themselves and their children to potential risks or false hopes.
The debate surrounding polygenic embryo screening highlights the need for nuanced discussions about the ethics of reproductive technologies and the responsibility that comes with using them.

I can imagine how overwhelming it must feel to consider all these possibilities when trying to have a child. On one hand, wanting to give your little one the best chance at life is totally understandable 
. But on the other hand, don't you think there's already enough pressure in the world without knowing every tiny detail about our kids? 
Like, do we really need that extra layer of uncertainty? 
. We gotta remember that life is full of surprises and that sometimes the best thing for us (and our kids) is just to trust in each other's love 
.
. We'll figure it all out as we go, okay? 
. It sounds like a bunch of complicated math and algorithms to me! 
. And even then, it's gotta be super transparent about the limitations and potential risks. We can't just rush into this without making sure we understand what we're getting ourselves into

Anyway, the fact is, these polygenic tests are super sketchy because they can only predict probabilities, not certainties. Like, what if an algorithm says your kid might be tall and smart, but it's actually just a random mix of genes that don't mean squat? 
or height 
... And people are actually using this tech to try and 'predict' things? Like, what if it's just plain wrong? 
. I mean, it's great that people want to make informed choices about their kids, but is this really the best way to do it? It feels like we're putting a price tag on human life or something... which, honestly, just freaks me out 
.
. We need to make sure these tests are safe, accurate, and not just some wild guess 
but c'mon! its so much more complicate than dat polygenic scores are probs way off 
we cant just reduce it to some numbrs irl. and whats w/ ppl thinkin they can make these decisions for their kids? thats some heavy responsibility 
lets get a better grasp on these techs before we adopt em 
. I mean, I get where people want to make informed choices, but isn't that kinda already happening with regular fertility treatments? Don't we have enough info already? 
, like how are we even sure these predictions are accurate? And what if they're wrong?! 
My friend's sister is trying to get IVF and she wants to do this polygenic testing thingy... I don't know, man. It just seems so... invasive? Like, don't they already know if you've got a family history of stuff that could be passed down to your kid? 
. Can't we just focus on finding healthy embryos instead of trying to predict every little thing about our kids?! 
. It's a slippery slope, you know? One day it's PGT-P, the next thing you know, we're talking about genetic editing... where does it end? 
... we gotta consider all the factors at play here - multiple genes influencing traits, complexity of human biology... cant just reduce it to a score or algorithm 
... need more research, need clearer guidelines... can't just rush into this without thinking about the consequences 
...
It's like, let's focus on making sure these tiny humans survive first, then worry about whether they'll be super smart or whatever 
.
And don't even get me started on the accuracy of these tests... they're probably way off 
. Let's just focus on having healthy kids and not worrying about their future grades or height, okay? 
.
. Like, what's next? Knowing our kid's chances of being a genius just because of their DNA code 
. Multiple genes with differing effects? Yeah, no thanks
