Success at 42 with Own Eggs in Thailand: A High-Age IVF Journey (Real Patient Story)
At 42, with an AMH of 0.3 and three failed IVF cycles in China, every doctor told her to try donor eggs. She insisted on one more try with her own eggs in Thailand — and her first transfer succeeded. This is her complete story.
Success at 42 with Own Eggs in Thailand: A Real Patient Story
The following account is based on a patient's real experience (pseudonym "Xiaoru"), documented with her consent through AddBaby. Some personal details have been anonymized; all medical data were confirmed by the patient.
Her Starting Point: Three Failures, Everyone Suggesting Donor Eggs
Xiaoru, 42, executive in Shanghai.
She and her husband had spent years saying "we'll have children once things settle down." By the time she started trying at 40, her ovarian reserve had declined significantly.
Initial test results:
- AMH: 0.3 ng/mL (normal for 35-year-old: ~1.0; ages 20-35: ~1.5-4.0)
- Antral follicle count (AFC): 1 left, 2 right — 3 total
- FSH: 12.8 mIU/mL (elevated, indicating reduced ovarian reserve)
Her first doctor's response: "With AMH this low, I strongly recommend considering donor eggs."
She didn't give up. She pursued IVF at a leading hospital in China:
Cycle 1 (Top-tier Chinese hospital, short protocol):
- Retrieved: 2 eggs
- Fertilized: 1
- Transferred: 1 day-3 embryo
- Result: Failed to implant
Cycle 2 (Same hospital, minimal stimulation):
- Retrieved: 1 egg
- Fertilized: 1 (poor grade)
- Result: Failed to implant
Cycle 3 (Different Beijing hospital, gentle stimulation):
- Retrieved: 3 eggs
- Fertilized: 2
- 1 reached blastocyst, 1 arrested
- Result: Weak positive HCG, spontaneous miscarriage
After three cycles, the Chinese physicians were clear: recommend donor eggs; do not recommend further attempts with own eggs.
The Turning Point: Why Thailand?
"I read online that Thailand's embryology labs — particularly the culture environment — are more advanced. I wanted one more try. If it still didn't work, I would accept donor eggs."
Through AddBaby, Xiaoru connected with a Bangkok fertility center (Jetanin) for a remote video consultation.
After reviewing her three cycle records, the Thai physician offered a different analysis:
"I see two issues with the previous attempts. First, the Chinese protocols were relatively aggressive — which can stress an already depleted ovary. Second, none of three cycles included preimplantation genetic testing (PGT-A). In women your age, embryo chromosomal abnormality rates are very high — approximately 50-70% at 42. This means that even when fertilization succeeds, the embryo itself may be chromosomally abnormal. This isn't a uterine problem. It's a probability problem."
The Thailand Protocol: What Was Different
1. Minimal Stimulation (Gentler Approach)
"Lowest possible stimulation doses to protect a limited reserve. We prioritize quality over quantity."
Protocol: Oral letrozole + low-dose gonadotropins, 9 days total.
2. PGT-A Genetic Screening — The Critical Difference
This was the game-changer.
After retrieval and fertilization, embryos developing to day 5 (blastocyst stage) had a small number of cells biopsied for comprehensive 24-chromosome analysis. The results identified which embryos were chromosomally normal — only normal embryos would be transferred.
"They retrieved 4 eggs, 3 fertilized normally, 2 reached blastocyst. PGT-A showed 1 chromosomally normal, 1 abnormal. Without PGT-A, there was a 50% chance I would have transferred the abnormal one. The results would have been predictable."
3. Precise Endometrial Preparation
Before transfer, the Thai team evaluated Xiaoru's uterine lining in detail, including an Endometrial Receptivity Analysis (ERA test) to identify her optimal transfer window. Results showed mild "asynchrony" — her window was slightly offset from the standard, which ERA helped correct precisely.
Transfer Day
By transfer day, Xiaoru had prepared herself mentally for another possible failure — "one more try, then I'll accept donor eggs."
"The transfer itself took about 10 minutes. The doctor said 'good luck' and I was moved to the recovery room. Very calm."
Day 12 post-transfer: blood test in Bangkok.
bHCG: 168 mIU/mL
Positive.
"I started crying immediately. Not from joy, exactly. From disbelief."
Day 28 post-transfer: ultrasound confirmed intrauterine singleton pregnancy with normal cardiac activity.
Back in China
Xiaoru returned to Shanghai with complete Thai medical records, continuing early pregnancy care at a private maternity hospital.
Week 11: NT scan normal. Week 16: First nuchal translucency (because of prior PGT-A, chromosomal risk was extremely low; additional testing was precautionary). Week 24: Anatomy scan — fetal development normal.
Week 38: Vaginal delivery. Daughter, 3.4 kg, healthy.
Xiaoru's Advice for Women in Similar Situations
"A few things I genuinely want to share:
First: Don't give up on your own eggs too quickly. Low AMH means fewer eggs, not necessarily poor quality. A small number of quality eggs with PGT-A selection may perform better than many poor-quality eggs.
Second: PGT-A is genuinely important for older patients. Chromosomal abnormality rates at 42 are very high. Not doing PGT-A means relying on luck. My three Chinese failures likely involved chromosomally abnormal embryos. Not the uterus's fault. Not the doctor's fault. Probability.
Third: Lab quality matters. My Chinese cycles produced no blastocysts in two of three attempts. Thailand produced 2 blastocysts from 4 eggs. Age progression is a factor, but the culture conditions — media quality, incubator stability — genuinely differ.
Fourth: Mental state matters more than I expected. I arrived in Thailand with low expectations — 'last try before donor eggs.' That reduced my anxiety compared to the desperate, high-stakes emotional state of the Chinese cycles. I think my body felt the difference.
Fifth: Donor eggs aren't failure — they're another path. If this hadn't worked, I would genuinely have moved to donor eggs. Having a child to raise is what matters. The biological connection is important, but not everything."
Reference Data: Real Success Rates for Older Women
From major Thai fertility center data:
| Age | Own Egg IVF Success Rate per Transfer | Recommendation |
|---|---|---|
| 35-37 | 35-45% | Actively pursue own eggs |
| 38-40 | 25-35% | Own eggs + PGT-A recommended |
| 41-42 | 15-25% | Own eggs + PGT-A after thorough evaluation |
| 43+ | 5-15% | In-depth physician consultation; donor eggs may be recommended |
Note: These rates reflect post-PGT-A transfer success rates. Individual variation is significant — AMH, AFC, and previous IVF history are all important factors.
