My wife has endometriosis [1]. IVF didn't take until our 3rd cycle (using at least 3 embryos each time).
Also, we were given the option every cycle to selectively reduce [2] embryos if too many took (luckily, that was never necessary). This was in the US.
/u/gyardley mentions that its not easy, convenient, and painless. The most expensive procedure in IVF is where you stimulate a woman's ovaries in order for them to overproduce eggs for ultrasound-guided retrieval (using an extremely long, large bore needle); as soon as medical science is close enough to converting stem cells filtered out of blood into reproductive tissue (and we're extremely close, believe me; I have done my homework), IVF will be an outpatient procedure no more expensive than an expensive dental appointment.
As a full disclosure my percentage comes from my research on bovine embryos. But I think viability percentage approximately matches your experience, especially when you consider that I'm used to working with ostensibly healthy individuals who could conceive naturally.
If they had dumped 10 embryos each cycle the story would have been different.
