No, your missing the key word 'MOST"
“ but some physicians say that MOST IVF patients are not interested in single-embryo transfer”
Where in the world are you getting the idea that "few" discard lives? Even if there are 5 made and three implanted, where do you think the other two go? To suspended animation where they eventually erode.
And honestly, you have said over and over that clinics don't implant more than three or four. You have given no links stating this. The proof is in the references.
The reason most IVF patients in the U.S. are not interested in single-embryo transfers (SETs) is that the pregnancy rate of SETs is lower than the traditional IVF transfer of 2-3 embryos, although the pregnancy rate is improving every year.
An IVF cycle costs around $10K, and with SET pregnancy rates around 20%, and traditional IVF pregnancy rates around 40%, many patients still avoid SETs, especially after multiple failed cycles.
And you have yet to find ONE clinic that publicly states they will implant more than three.
I've had enough of your circumlocution. You go ahead and keep citing your hysterical 'facts'. When YOU have gone through IVF, or have been through it first hand with someone, let me know, k? Ciao.
