Not bad for an old girl, I guess. I'm just hoping that all of the attrition is done, and that each of the 3 left is good baby-making material.
Since I am pretty quantitative, here's the final rundown, with numbers:
18 eggs retrieved
17 fertilized via ICSI (94% retained)
10 fertilized on day 1 (59% retained, 55% of retrieved total)
8 still going on day 3 (80% retained, 44% of retrieved total)
5 blastocysts on day 5 (62% retained, 28% of retrieved total)
3 good enough to freeze/ use (60% retained, 17% of retrieved total)
So our percentage attrition from retrieval to "good enough at 5 days enough to possibly become a baby"? 83%.
(incidentally, as I was re-reading this, I had a "12 days of Christmas" moment. So now I am humming that to myself with the words replaced. Oy.)
I wish like hell there was some place where I could compare these numbers to some sort of averages and then see associated live birth rates based on numbers of embryos transferred. Because I am in the throes of an obsessive Google-a-thon, and that sort of data, or an article that talks all about regressions and correlations is just what I need to keep occupied.
(If any of you know of such data, please let me know where I can find it!!)
I think I am going to step away from the keyboard and bake something. Seriously, my fingers are going to start to bleed soon from too much typing.
