Oops - 12:10 poster here. Meant to say that Day 5 embryos have a slighter higher success rate than Day 6 embryos.

My understanding is that it also depends on how old the embryo is, as well as the quality of the embryo. Day 6 embryos have a slightly higher success rate than Day 7 embryos. However, even Day 7s can take - I think that I found one study that found Day 7 PGS normals had about a 20-25% live birth rate. (Though another study said lower.). Our Day 7 didn’t implant, but it was enough of a possibility that it was worth trying, since it was our only option from that batch. Our RE had also been open that our odds weren’t great with a Day 7, so we were sad but not surprised.

Had a successful transfer with live birth from a PGS-normal embryo produced at age 41. Gave birth at 44.

I had a successful birth at 38 of a PGS normal. My RE (Payson, CCRM) said the chances were 60-70% and there was a 4% chance of miscarriage.

What I meant was, are tested embryos from a 25 yo more likely to succeed than tested embryos from a 40 yo?

From my post 01/17/2020 13:53- my RE said my age shouldn't be an issue but not too do it after a certain age, I think he said 45. I don't know why he said that. The embryos don't age and they manipulate your body with hormones and make sure the lining is ready so age shouldn't be too much of a factor.

2 pgs normal from retrieval at 41 yo (unexplained infertility). First FET did not implant and the second one resulting in a live birth.

Two of my three PGS embryos implanted. First transfer failed.

I was also told 60-70%. My first FET with a normal worked - good luck!

I had a successful FET with PGS normal embryo at 38; delivered after turning 39. I was told our chances were above 60% I want to say 65-68%? This was from RE at Shady Grove. I am now 41 and have another frozen PGS normal embryo and was quoted the same success rate. I was encouraged not to wait until I was 45 but was told age does not effect the success. Nothing is guaranteed but I feel pretty optimistic about it, especially since my one other embryo implanted... but I've known a co-worker who had a PGS normal FET that was not successful so I'm trying to manage expectations. Good luck!

Also! I did 2 retrievals resulting in about 8 mature eggs being fertilized each time, with 3-4 making it to 5-day testing. The first batch of 4 "great looking!" embryos were ALL abnormal and 2 of the second batch (3-4 embryos, I forget) were normal. Because of that experience, I highly recommend PGS to anyone who can afford it.

That’s the success rate we were informed about by our RE - 60% and maybe a little higher in our situation because we did not have known fertility problems (same sex couple). Though we had no success with 6 IUIs back in early 30s (including some medicated).

We only had two PGS normal embryos and both were successful transfers. One at 38 and second at 39 (currently pregnant with that one).

Don’t know the stats but miscarriage rates are definitely lower with PGS normals that implant. I might have heard something like 10% for my age group. This was a major benefit of testing — more likely to implant and more likely to stick around.

maternal age is 37

What's the effect of maternal age?

I've read it is 60-70%; does that sound right?

If the test is positive with a PGS tested embryo do miscarriage rates drop? or are they still 20%?
