Before my two failed embryo transfers, I was convinced the problem was my embryos. It wasn’t until my third cycle, when my doctor finally ordered insulin and fasting glucose tests, that I understood my body had been waving red flags for over a year. This post is for anyone stuck in the same loop — repeated failures, endless Googling of “what are IVF success rates,” and no clear answers.
Two Failed Transfers, and the Lab Line I Ignored for a Year
I was 36 with an AMH of 1.6 — not terrible on paper. My first fresh transfer failed. Four months later, a frozen blastocyst transfer failed too. Total damage: roughly 110,000 RMB and a lot of crying in parking garages. When I finally went back through my old lab reports, there it was: fasting insulin at 28, nearly double the upper reference limit. I’d seen that number the first year and simply brushed past it. My doctor was blunt: insulin resistance degrades endometrial receptivity. The embryos can be perfect and still have nowhere to implant.
Your actionable checklist: if you’ve had more than 2 failed transfers, demand a fasting insulin test plus glucose tolerance testing before your next cycle. Don’t just track endometrial thickness and the standard six-hormone panel.
Three Months of Blood Sugar Control — What Actually Changed
After diagnosis, I did three things: swapped white rice for mixed grains, walked briskly 40 minutes every day, and took metformin as prescribed, titrating from 500mg up to 1500mg. At my three-month recheck, fasting insulin dropped from 28 to 14, and my HbA1c came in at 5.1. My doctor said transferring in this metabolic state would meaningfully improve implantation odds. Honestly, those three months were harder than any stimulation cycle — but with numbers like that staring back at me, slacking wasn’t an option.
Your benchmark: if your BMI is over 24 and your cycles are irregular, lose 5% of body weight before starting a cycle. It’s more cost-effective than paying for one extra egg retrieval.
What IVF Success Rate Justifies Another Attempt?
I brought my data to my clinic and got a refreshingly honest answer: under age 38, single blastocyst transfer per cycle, clinical pregnancy rates hover around 50%. But that’s a population average — your individual odds depend on endometrium, immune factors, and metabolic health. I ran the math: two more self-carried cycles would cost about 160,000 RMB, with stacked cumulative success around 70%. That still left a 30% chance I’d walk away with nothing. That uncertainty is exactly what pushed me to seriously look at overseas options.
A formula you can use today: take the single-cycle success rate for your age band, multiply it by the number of cycles you can still afford. If that number falls below 60%, it’s time to seriously evaluate alternatives.
When I Added Kyrgyzstan Surrogacy to My List, I Checked These Three Documents First
What I learned along the way: surrogacy is legally permitted in Kyrgyzstan for married couples, and the child can be registered directly to the intended parents. I compared the current policy situations in Georgia and Thailand, then had my agency produce a full Kyrgyzstan quote: roughly 420,000 RMB all-in, nearly 200,000 less than the Thailand package. Three documents got my closest scrutiny: the surrogate’s full medical and psychological screening reports, the contract clauses covering pregnancy risks and handover responsibilities, and the clinic’s blastocyst formation rate (they reported 55%). One warning: any verbal promise from an agency gets written into the contract as an annex. Every single one. Miss nothing.
My conclusion is specific: first, test for insulin resistance — it’s the unturned stone behind many repeated failures. Once your numbers are under control, give yourself two self-carried cycles. If the stacked success rate still doesn’t pencil out, fold a legally viable path like surrogacy in Kyrgyzstan into the comparison early. Don’t wait until your fourth failure to start researching. Time is the most expensive line item in this entire process.
