12 fertilized, 8 made it to freeze - is this average?

Question

We had 14 retrieved, 12 fertilized, 3 made it to blastocyst on day 5, 
5 more on day 6 (today). Doc says we'll transfer after PGS testing, SIS procedure, a week of birth control followed by estrogen patches and progesterone injections...so about 4 weeks from now.
Is 8 blastocysts about average? 
I'm 40 with 3 children, non specific secondary infertility.
Any guesses how many we could see viable after our PGS testing?

Answer

I had 9 retrieved, 8 mature and fertilized, 5 made it blastocyst and sent for testing. I had 1 normal, 3 abnormal, and 1 no results.. currently 4 weeks 2 days pregnant from the first fet and I am 42!

Answer

Sounds like pretty good numbers. I think there is so much variance during PGS testing just like the rest of the process. I am 45 and had 28 eggs retrieved, 22 mature, only 1 blastocyst on day 5, 2 more on day 6. We sent 3 for testing and 1 was good. I am currently 35w pregnant.

Answer

I think that’s great for 40. I am younger and I have never had this many blastocysts on day 5. Hope it continues so smoothly and successfully for you. Good luck!

Answer

Especially for being 40 it's great! I am 29, hubby is 33, and we had 11 mature, 8 fertilized, 7 frozen as 5 day blasts. 😊 We were told even 50% of those fertilized being frozen is a good outcome.

Answer

It sounds pretty great for 40!!
What protocol did you use? I’m about to get my cycle cancelled :( there are only 2 follicles after 7 days of stims. I just turned 41 and would have loved those numbers congrats!

Answer

Everyone is so different so It’s hard to predict. Good luck though!

Answer

Everyone is different but I think your numbers are a good sign! I’m 34, husband is 41. Retrieved 14, 13 mature, 12 fertilized, 0 on day 5, 4 on day 6. All 4 came back normal from PGS.

12 fertilized, 8 made it to freeze - is this average?
