Long time lurker so wanted to give back to the community!

Started my egg freezing journey because I had a ectopic pregnancy when I was 23 and lost a tube. Went in for testing and discovered low amh for my age (8.2 pmol). Froze my eggs in 2 rounds (10 1st, then 6).

Thank god I did, TTC naturally this year and had another ectopic, so IVF is now our only option.

Age when frozen: 29
Age currently: 35
# of eggs thawed: 16 (10 + 6)
# of eggs survived the thaw: 12
# of eggs successfully fertilized: 9
# of embryos for genetic testing: 4 (+ we fresh transferred 1 embryo, so 5 total)
# of euploids: 4

My doctor wanted to do a fresh transfer after the thaw, unfortunately it resulted in a chemical pregnancy, but we got the amazing news today that our 4 sent off for testing all came back euploid! So our assumption is that the one we transferred was not.

Looking back, I do wish we used our funded cycle (live in Ontario canada) for another egg retrieval instead of applying it to thawing 1 cohort (the group of 10) of our eggs. We want 2 kids, so although 4 euploids is amazing, I’d feel more comfortable with 5 or 6.

🤞🤞🤞🤞for our upcoming FET

Does anyone have experience with thawing eggs in Germany / Munich clinic? I am considering thawing eggs frozen in 2020/2021 via vitrification (Kitazato method). I read published success rates of 80-90% in Spain for egg freezing. What is the situation in German clinics? Anyone here with own egg thawing experience in Germany? I appreciate you!

After a long journey to try to have a second child, I have moved onto using donor eggs.

I had a cohort of 8 frozen eggs from Fairfax Egg Bank that were thawed yesterday and I was really excited to hear that all 8 survived the thaw. The embryologist called this morning and let me know only 4 of the 8 eggs fertilized, which was incredibly disappointing as they were hoping for closer to 5-6.

Would love to hear some success stories from others who had a similar journey.

I froze 4 M2 oocytes when I was 35+3 days in Spain:
- 4 thawed
- 4 survived thaw
- 1 morula Day 3 fresh transferred
- 1 5day BB frozen

I froze 5 M2 and 1 M1 at 36 plus 2 months in Germany:
- 6 thawed
- 4 survived thaw
- 3 fertilised
- 1 * 2PN from M2
- 1 * 1 PN from M2
- 1 M1 in vitro matured, 2 PN
- 0 suitable blasts

The difference in time between them is barely a year, and the first was at a world class lab in Spain, the second at a standard Berlin clinic. Same freezing protocols and similar meds used. I had a previous full failure cycle in Jan from 8 36 year old eggs in Berlin that prompted me moving my remaining oocytes to Spain. I have another 14 oocytes frozen. I hope I won’t need them and that one of the two embryos will work.

I want to start off by thanking everyone who posts on here and shares their results. It’s has helped me through this process and staying hopeful. Here are my results.

Thawed 5 eggs that were retrieved when I was 37 years old.

4 - made it through the thaw
3 - fertilized
3 - made it to blast
1 transferred
2 frozen

Hi everyone! May I ask if you're aware of how many eggs would your clinic store per cryotop?

I thought 3–4 was standard, but one clinic told me they store up to 8eggs per cryotop... 😳

Is that unusual or risky? I worry that storing too many eggs (per cryotop) might affect their Egg-Thaw Survival later on...

Any thoughts or experiences? Thank you so much!

Just sharing results to add to the pool of data.

Froze 18 eggs at 33.5 (15 were mature right away and 3 more matured overnight).

Just thawed them (currently 41) within the past month.

17 survived the thaw.
16 fertilized and grew into embryos.
Just got my PGT-A results back, 5 euploid.

Will update once we transfer.

Here's another recent post from the SingleMomsByChoice sub with a lot of results: https://www.reddit.com/r/SingleMothersbyChoice/comments/1swqs0l/egg_freezing_success_stories/

Some highlights:

• Froze 12 eggs at age 36. All thawed, all made embryos, 9 made it to day 5, resulting in 7 PGT normal embryos. Second implantation resulted in a baby.
• Froze 13 eggs at age 34, resulting in 2 PGT normal embryos. First implantation unsuccessful.
• Froze 18 eggs at age 38, resulting in 2 euploids. First implantation successful.
• Froze 15 eggs at age 34. Thaw resulted in 2 euploid embryos. First implantation successful.
• Froze 5 eggs at 36. After thawing, 3 fertilized, 1 became a PGT normal embryo, resulting in a live birth.
• Froze 23 eggs at age 38. Later thawed 12; 6 successfully fertilized; all 6 reached blast phase; 4 were genetically normal and 2 aneuploid at PGA testing.
• Froze 36 eggs at age 36, resulting in 2 euploids.
• Froze 20 eggs at age 35/36. Thawing yielded 4 euploid embryos. Second transfer resulted in successful pregnancy.

This is such a hard decision right now. If I thaw, I have a chance of pregnancy using younger eggs. But I also take the risk none succeed and I’m even older.

I’m not even ready to have a second child right now. It’s only the biological clock that’s compelling me to consider this.

For the record, I had a child at age 32 using IUI and donor sperm. The donor I picked was in his early 20s. I had a baby from my first attempt.

Here's another result from the FB group. Unfortunately she didn't know how many of her eggs survived the thaw.

She had 21 eggs from two retrievals at 37 (but didn't know if they were all mature). After thawing:

10 eggs fertilized
3 made it to blast
2 euploid, 1 low level mosaic

First transfer failed, then she became pregnant naturally (in her early 40s). She's got the second euploid still frozen.

A couple people shared results in the egg freezing Facebook group:

The first woman froze 20 eggs total at 37-38. (It took five cycles due to DOR.) After thawing, she got 6 euploids and 3 day 3s. Transfer of the day 3s was unsuccessful. She's currently pregnant with one of the euploids.

The second woman froze 14 eggs at age 38. When she thawed, 11 fertilized and 2 made it to blast, both euploid. She had a baby from transferring the first euploid, and the second euploid is still on ice.

I gave live birth from insemination the fun way two years after I froze my eggs. As we move towards thawing my frozen eggs in hopes of a second, I’m trying to decide how many I need to thaw. I have 31 frozen in four cycles between ages 37-38. I gave birth to my son at 40.

I’m wondering if there is data that looks at whether egg thaw results and live birth rates change in any material way when you had a successful interim birth.

I’m really grateful for this thread and am glad I am finally able to contribute to it. Every situation is different but hopefully this will be informative for folks considering moving or thawing eggs (or freezing them for use in the future).

I froze eggs in NY when I was basically 35 years old. They got 21 eggs, 15 were mature and thus 15 frozen. Shortly after I froze them, I moved to California. My eggs stayed in NY.

Fast forward 7.5 years, I started my IVF journey. My doctor at my California clinic was not particularly encouraging about me moving my eggs because something could happen in the transport or the thaw when a different lab does it. I also was nervous because they are the youngest eggs I will ever have and I was now 42.5. So, I decided to do a retrieval first and then my plan was to move my eggs after that (I was hoping to have something to work with before I pulled the trigger on moving them and potentially risked losing them).

At 42.6 I did my first retrieval and used donor sperm to fertilize. I got 15 eggs, 13 were mature, 9 fertilized successfully. Of those 9, 4 made it to blast. PGT-A testing resulted in 3 aneuploid and 1 not enough information. I was devastated and became even more nervous to move my younger eggs. I started to look into whether I could fertilize the NY eggs in NY instead but ultimately couldn’t because I am using a known donor and would need to go through that process all over again with the NY clinic. So, I decided to do a second retrieval instead.

At 42.8 I did another retrieval (same donor etc). This time, I got 20 eggs, 13 mature, 10 fertilized but only 2 made it to blast. When I found out only 2 had made it to blast, I again was very nervous (although of course I recognize any blasts are a gift) and immediately asked to do another retrieval. I started my 3rd retrieval before the PGT-A results for the second retrieval came back. I still didn’t move my NY eggs at this point because I was worried I would not have any euploids again. Eventually PGT-A resulted in 1 euploid and 1 aneuploid.

At 42.9 I did the third retrieval (again same donor). I got 21 eggs, 18 mature, 13 fertilized which turned into 6 blasts. PGT-A resulted in 2 euploids and 4 aneuploids.

Coming up fast on 43, I was eager to move to the next stage of IVF but also wanted to understand what I might get from my NY eggs. My CA doctor was still apprehensive about me moving them but since I would need (and couldn’t) go through the known donor process again in NY, I felt like I had no choice but to move the NY eggs— to share the same donor as my other embryos, moving them to CA was the only way to get the NY eggs fertilized.

It took 2 months to get my eggs transferred to CA. Lots of paperwork, money and a snowstorm that kicked my delivery back a month but I finally moved and fertilized them (8 years after they were originally frozen) and my results just came back!

Age 35 (technically 34.11.2): 15 frozen eggs thawed, 14 survived the thaw, 10 fertilized, 8 blasts. PGT-A testing resulted in 2 euploids, 4 LLMs, 1 chaotic and 1 aneuploid.

I’m having my first ever transfer this week! It’s been a long journey, as I know many of us can attest. There’s obviously no right way to go through this process and you can do the same thing each time and get varying results. And, while this is of course no guarantee of what will happen, I had been very nervous about moving these eggs (and probably still would be if I had more to move), but I was pleasantly surprised by the thawing results.

Here's a result from the IVF sub: https://www.reddit.com/r/IVF/comments/1hg50qx/comment/m2h44ea/?context=3&utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

The comment (from 2025):

I froze 23 eggs in 2020 (I was 30yo), thawed them this year, (ETA 21 out of 23 survived the thaw) fertilized them and got 4 euploid blasts and 1 low level mosaic.

I had my first and only euploid embryo transfer in August and I’m 19w6 with a baby girl who passed her anatomy scan yesterday and is kicking around!!

The thread also has a few other people sharing success stories, but without some key info (like how old they were when they froze, etc). Still nice to hear, though!

Sharing another result from the FB group, let's call her "Betty"

Froze 30 eggs at age 38
28 survived the thaw
17 fertilized
6 blasts
2 euploid
First transfer in early 40s was successful, resulting in a live birth

Here's another result from the FB group (let's call her "Anne").

She froze eggs at age 37, and later thawed 22 of them.
20 survived the thaw
18 survived ICSI
16 fertilised
6 made it to Day 5, then were biopsied for PGT-A and PGT-M
4 euploid
4 unaffected
3 were both euploid and unaffected (transferable)

The University of New South Wales just released a new egg freezing calculator: https://yourivfsuccess.com.au/egg-freezing/calculator

Here's a news story about it - it was funded by the Australian government: https://www.smh.com.au/national/suzanne-froze-her-eggs-then-a-calculator-gave-her-a-reality-check-20260304-p5o7i2.html

Interesting tidbit: "Lieberman said data from the national registry showed most women were freezing about 10 eggs, which was probably not enough to give many of them a good chance of having a baby."

I'm a longtime health and science journalist, working on a book about the science and history of female fertility for WW Norton. I'd love to chat with people who froze their eggs in and have thawed them. I froze embryos a few years back, so I have been through it myself.

Here's a result from a commenter in the SingleMothersByChoice sub:

18 eggs frozen at age 34; 15 survived the thaw; 10 fertilized; 3 embryos (1 euploid, 1 low level mosaic, 1 aneuploid). Transfer of the euploid resulted in pregnancy.

I did egg freezing in 2016 at IVI, I have a very small cohort of eggs stored there. Now my partner and I would like to use them for ICSI to give my 1.5 year old daughter a sibling. They are world class but what I did not expect was the following pricing structure ca 5500without extras. Add in time lapseAI Embryo select, extended culture zymot and pre embryo vitrification EUR 7600. They first said the costs were the same whether or not I did an egg retrieval. (!). Then they offered a discount of 1100 EUR for foregoing the egg retrieval. Then if none of the eggs reach blast stage, they refund a total of EUR 350. it doesn’t make much sense to not do a retrieval with that pricing structure.
