I did two fresh embryo transfers in Thailand. Neither implanted. I was 38, AMH 1.1, and my doctor kept telling me the embryos “looked great” — yet no pregnancy. It took me two full failures to realize the problem probably wasn’t the embryos at all. It was how the whole plan was calculated, or rather, how nobody bothered to calculate anything. If you’re in a similar spot, here’s exactly how I re-did the math before moving my cycle to Georgia.
Two Failed Fresh Transfers Taught Me My First Real Number: Lining Thickness
Confession: I had never seriously read my own endometrial report. On my first transfer day my lining was only 6.8mm, and the doctor transferred anyway. After the failure I dug through overseas literature and consulted a second clinic — most doctors agree that above 8mm, implantation rates improve noticeably. A lining under 7mm is exactly where you should be considering a frozen transfer or endometrial perfusion (PRP/infusion) instead of pushing a fresh cycle.
For round two I insisted on 28 days of preparation. My lining reached 7.5mm. Still under the line. Still failed.
The takeaway you can use immediately: if your lining keeps coming in below 7mm, do not rush into a transfer cycle. Make your doctor explain why you’re proceeding anyway. That number cost me two failed cycles to learn.
What Separates a 50% Blastocyst Lab From a 35% One — I Went to Georgia to Find Out
Once I decided to switch countries, I wavered between Georgia and Thailand. The lab director at a Tbilisi clinic walked me through their 2026 data in person: blastocyst formation rate around 52%. The Thai clinic I’d worked with? Roughly 38%. Where does that gap come from? Time-lapse incubators, the embryologist-to-case ratio, and whether they uniformly perform PGT testing at the blastocyst stage.
I’ve also seen agencies quote a glossy “50% transfer success rate” without ever clarifying whether that’s calculated per transfer or per egg retrieval cycle. Those are two very different numbers.
Red-flag check you can use right now: when requesting data from any center, push on three denominators — per retrieval cycle, per transfer cycle, and per live birth. Depending on which one they use, the same program can swing by 20 percentage points.
On Registration Day in Georgia I Prepared 5 Documents — and Was Still Missing One
Before starting your cycle officially in Georgia, there’s a file-registration step. I scanned everything in advance: six-panel hormone panel, AMH, hysteroscopy records, the male partner’s semen analysis, and infectious disease screening. Five documents.
On arrival I discovered I was missing one: a breast and thyroid check done within the last six months. The local clinic required it as a hard rule, so I had to redo it there — costing me extra lari and two full days.
Your practical checklist: before registration, ask the clinic directly for their original document checklist. Do not rely on the generic list your agency sends you. Requirements differ a lot between clinics, especially the thyroid and breast screening — plenty of people miss it, just like I did.
The Most Underrated Factor in Surrogacy Success: the Surrogate’s Screening Report
Half of any surrogacy plan’s outcome rests on the surrogate. I scrutinized three things hard:
Obstetric history — at least one full-term vaginal delivery required. My surrogate was 32 with two successful pregnancies. BMI — required to fall between 22 and 28. Any candidate over 30, I rejected outright. Psychological evaluation — a proper program includes a one-on-one in-person interview, not a checkbox questionnaire.
The center told me that surrogates who clear the full screening panel push per-cycle live birth rates above 60%. Match casually with an unqualified candidate, and all that risk lands on you.
Hard rule before signing: demand the surrogate’s complete medical and psychological screening originals. If even one item is missing, hold your payment.
If you’ve been through failed transfers too, don’t rush to change countries. First, untangle three things: your lining thickness, the lab’s statistical denominators, and your registration paperwork. And if you do decide to switch — like I did — take two weeks to collect full data and original screening reports before you sign anything. Success rates aren’t something you ask for. They’re something you verify, report by report.
