Pgt-a not recommended by uk regulator - what’s the medical view in US?
The UK has the most advanced regulator of IVF I think in the world. This includes categorising add ons by a traffic light system and pgt-a isn’t rated green.
At a talk by the leading embryology researcher here it was explained that the cells tested are placenta cells, and in many cases 1) contain multiple dna strains so it’s contentious how relevant the strain tested actually is 2) the inner cell mass that becomes a baby is completely separate so no guarantee the 2 correlate and 3) doing the treatment can technically only maintain or reduce your chance of success, not increase, as you are either maintaining or reducing the available embryos to transfer.
In all cases there’s genetic tests offered at 12 weeks anyway.
The hospitals here don’t offer pgt-a at all. The view is they cost 50% of running another full cycle, so to be worthwhile the increase in chance of success needs to be 50% of the increase in success from of the new cycle, and it’s not. It doesn’t increase success on the whole at all. It only increases the chance the first transfer succeeds. Private clinics universally do them and advocate for them but those who don’t stand to profit from it see it differently.
Wondering what the view is in other countries.
