1. Success Stories for Advanced Age Patients
Advanced maternal age (generally 35+, medically "very advanced" at 43+) is one of the most common challenges in IVF. With increasing age, ovarian reserve diminishes, egg quality becomes harder to guarantee, and the proportion of chromosomally abnormal embryos rises. Yet the following two cases demonstrate that even under difficult conditions, scientific protocol design and precise laboratory technique can still achieve remarkable results.
Case A: Age 43, AMH 0.3 — Own Eggs, Third Attempt Success
Background: Ms. Lin, from Guangdong, age 43, married. She had undergone two IVF cycles at leading tertiary hospitals in China, both unsuccessful. The first cycle failed due to low egg count (only 2 retrieved) with no viable embryos; the second cycle transferred one blastocyst that failed to implant, and she was told to consider donor eggs. Unwilling to give up her genetic offspring, she contacted AddBaby through a friend's referral.
Assessment Findings:
- AMH 0.3 ng/mL (extremely low reserve)
- AFC (antral follicle count): only 3
- Uterine lining thickness and morphology normal
- Previous failure analysis: likely embryo quality issues (chromosomal abnormalities) rather than uterine receptivity problems
AddBaby Protocol:
- Mini-IVF protocol (low-dose FSH + letrozole) to minimize OHSS risk while protecting remaining follicle quality
- This stimulation cycle yielded 4 eggs retrieved, 3 mature, cultured to blastocyst after fertilization
- All 3 blastocysts sent for PGT-A (Preimplantation Genetic Testing for Aneuploidy) screening
- Results: 1 chromosomally normal (euploid), 2 abnormal
- Single euploid embryo transfer with individualized endometrial preparation
Outcome: Beta-HCG positive 14 days post-transfer; 12-week ultrasound confirmed intrauterine singleton pregnancy with normal heartbeat. Vaginal delivery at 40 weeks of a healthy baby girl, birth weight 3.2 kg.
AddBaby Commentary: This case perfectly illustrates the value of PGT-A. Ms. Lin's previous failures were very likely due to the transfer of chromosomally abnormal embryos without genetic screening. PGT-A allowed us to identify the one correct embryo, and success was achieved on the first transfer with it. For more on PGT-A technology, see our AddBaby PGT-A embryo screening guide.
Case B: Age 46, Donor Egg IVF — Successful Twin Pregnancy
Background: Ms. Chen, from Shanghai, age 46. Menstrual cycles had become irregular; AMH <0.1, with clear signs of premature ovarian insufficiency. Assessment confirmed that her own eggs were no longer suitable for use. After discussion with her husband, they decided to proceed with donor egg treatment.
Key Concerns:
- Psychological acceptance of donor eggs: worry about lack of "genetic connection" with the child
- Trust in the donor's identity and health status
- Understanding the risks associated with twin pregnancy
AddBaby Support and Communication:
- A counselor facilitated discussions with Ms. Chen and her husband about the psychological journey of accepting donor eggs, emphasizing the epigenetic influences of carrying and nurturing a pregnancy
- Complete medical records of the donor were provided (age 22, healthy, genetic disease screening negative, AMH 4.2 ng/mL)
- Detailed discussion of double embryo transfer risks and benefits; informed consent obtained for double transfer
Protocol:
- Donor IVF: 12 eggs retrieved from donor, 10 mature, cultured to day 5, yielding 5 blastocysts
- Ms. Chen's endometrial preparation: estrogen + progesterone, lining reaching 12mm triple-line pattern
- 2 high-quality blastocysts transferred
Outcome: Post-transfer HCG positive; twin pregnancy confirmed by ultrasound. Uneventful pregnancy; cesarean delivery at 37 weeks of two healthy baby boys, birth weights 2.8 kg and 2.9 kg. At discharge, Ms. Chen told our coordinator: "When I held them, I knew they were my children. Genetics turned out not to be the most important thing."
2. Breakthroughs in Male Factor Infertility
Male factor accounts for approximately 40–50% of all infertility cases. Oligospermia, asthenospermia, teratospermia, and azoospermia were once formidable barriers to fertility. However, with mature ICSI technology and the application of sperm DNA fragmentation testing, even severely compromised sperm can now yield successful outcomes.
Case C: Severe Oligospermia — ICSI + PGT-A Success
Background: Mr. Wang, from Beijing, age 36. Semen analysis showed sperm concentration of only 50,000/mL (normal >15 million/mL), motility 30% (normal >40%), and sperm DNA Fragmentation Index (DFI) of 42% (normal <25%). Three failed IUI cycles in Beijing; one conventional IVF attempt with poor fertilization rate (only 30%) and no viable blastocysts.
AddBaby Assessment:
- Sperm quality is the core issue: high DFI indicates severe DNA damage; the low fertilization rate in conventional IVF was expected
- Optimize sperm source: recommend 2–3 days abstinence before collection; use specialized sperm selection technique (IMSI — intracytoplasmic morphologically selected sperm injection)
- Use ICSI instead of conventional IVF to ensure fertilization
- PGT-A screening for all embryos to exclude chromosomally abnormal embryos that high DFI may produce
Protocol Execution:
- Wife's stimulation: 11 eggs retrieved, 9 mature
- Mr. Wang: IMSI sperm selection + ICSI injection
- Fertilization rate improved to 78%; 7 fertilized
- Day 5 culture: 5 blastocysts formed
- PGT-A results: 2 euploid, 3 abnormal
- First transfer: 1 euploid embryo
Outcome: Successful implantation, uneventful pregnancy, vaginal delivery at 36 weeks of a healthy baby boy. Mr. Wang later reflected: "Doctors in China basically told me my sperm was no good and suggested we use donor sperm. Coming here, I learned my sperm was actually still usable — it just required more refined processing."
Case D: Obstructive Azoospermia — PESA Retrieval + ICSI Success
Background: Mr. Zhang, age 30, diagnosed with congenital bilateral absence of the vas deferens (CBAVD), a genetic condition causing complete absence of sperm in the ejaculate (obstructive azoospermia) while testicular sperm production typically remains normal. He was told in China that donor sperm was the only option; unwilling to accept this, he contacted AddBaby through the website and traveled to Thailand.
PESA Procedure (Percutaneous Epididymal Sperm Aspiration):
- Urological surgeon aspirated sperm from the epididymis using a fine needle under local anesthesia
- Procedure time approximately 30 minutes; normal activity resumed the same day
- Sufficient motile sperm were retrieved
- Same-day ICSI fertilization with wife's eggs
Protocol Execution:
- Wife (age 28, normal ovarian reserve): standard stimulation, 14 eggs retrieved, 12 mature
- PESA sperm + ICSI: fertilization rate 82%; 10 fertilized
- Day 5 culture: 7 blastocysts, 4 high-quality
- All blastocysts frozen; natural cycle frozen embryo transfer scheduled two months later
Outcome: First frozen embryo transfer failed to implant; second transfer resulted in successful pregnancy; vaginal delivery at 39 weeks of a healthy baby boy. As CBAVD is X-linked, the physician advised PGT screening for subsequent cycles to exclude carrier risk; a second cycle is now being planned.
AddBaby Commentary: Azoospermia does not mean zero chance of biological parenthood. For obstructive azoospermia patients, surgical sperm retrieval + ICSI achieves success rates comparable to normal sperm. Our AddBaby Thailand IVF guide covers different types of azoospermia and their management approaches.
3. Breakthroughs After Repeated Failure
"Recurrent Implantation Failure" (RIF) is typically defined as 3 or more transfers of high-quality embryos without achieving pregnancy. It's one of the most discouraging situations patients can face — enormous investments of time, money, and emotional energy with no result. The following two cases illustrate the critical importance of systematic root cause analysis.
Case E: 5 Failed Transfers — ERA Testing Reveals Displaced Implantation Window
Background: Ms. Liu, from Chengdu, age 39. She had undergone 5 embryo transfers in China — 2 fresh and 3 frozen — all unsuccessful. Embryo quality reports showed high-grade blastocysts (4AA/5AA); hysterosalpingography showed normal uterine cavity; chromosomes of both partners were normal; all routine tests were unremarkable. Ms. Liu carried a heavy psychological burden and had nearly given up on treatment.
AddBaby's "Detective" Approach:
AddBaby's chief reproductive specialist comprehensively reviewed Ms. Liu's medical history and noted that all her transfers had followed the standard endometrial preparation protocol — estrogen + progesterone with transfer on day 5. The specialist raised a key question: Was her implantation window actually on day 5?
- ERA testing (Endometrial Receptivity Analysis) was arranged: an endometrial biopsy was analyzed using gene expression profiling to precisely determine her personalized implantation window
- Results showed Ms. Liu's window was displaced by 24 hours — day 6 instead of the standard day 5
- A sixth transfer was performed at the adjusted timing (ERA-guided personalized Embryo Transfer, pET)
Outcome: Only the transfer timing was changed, using a previously frozen embryo. The first ERA-guided transfer resulted in successful pregnancy; vaginal delivery at 38 weeks. Ms. Liu said tearfully: "Before coming here, I no longer believed I could succeed. I never imagined that a one-day timing difference would be the entire answer."
Case F: PCOS + Endometriosis — Dual Diagnosis Success
Background: Ms. Zhao, age 33, from Guangzhou, with concurrent diagnoses of polycystic ovary syndrome (PCOS) and Stage III endometriosis. PCOS creates extremely high OHSS risk during stimulation; endometriosis impairs endometrial receptivity and also negatively affects ovarian reserve. She had undergone two egg retrieval cycles in China — the first resulted in OHSS hospitalization; the second had a biochemical pregnancy (early failed implantation) after transfer.
AddBaby Comprehensive Protocol:
Facing the "dual challenge" of PCOS plus endometriosis, AddBaby developed a multi-phase, multi-dimensional management strategy:
Phase 1: Safe Stimulation Strategy
- GnRH antagonist protocol (reduces OHSS risk)
- Close follicle monitoring with alert when E2 >3,000 pg/mL
- GnRH agonist trigger on retrieval day (replacing hCG trigger), dramatically reducing OHSS risk
- Freeze-all strategy: no fresh transfer after retrieval — allowing full body recovery before frozen embryo transfer
This stimulation cycle retrieved 18 eggs (PCOS produces many follicles of variable quality), 14 mature, 11 fertilized, 7 blastocysts. PGT-A screening yielded 4 euploid embryos. All frozen; no OHSS occurred.
Phase 2: Endometrial Preparation Optimization
- 3 months pre-transfer: GnRH agonist (Decapeptyl) down-regulation to suppress endometriosis lesion activity and allow the endometrium to "reset"
- Transfer cycle: hormone replacement protocol for endometrial preparation; ERA testing to personalize transfer timing
Outcome: First frozen embryo transfer (using best euploid embryo) failed to implant — analysis suggested the endometrium had not fully recovered. The GnRHa pretreatment duration was extended before the second transfer. Second transfer was successful; pregnancy progressed to 35 weeks, with cesarean delivery of a healthy baby girl.
4. Why So Many Patients Choose AddBaby
From the cases above, several dimensions distinguish AddBaby from other providers:
The Emotional Value of Full Chinese-Language Service
From the first online consultation through the treatment period in Thailand to post-return prenatal follow-up, AddBaby's Chinese-speaking coordinators are present throughout. In a foreign medical environment, language barriers amplify anxiety and distort information. Chinese-language service is not merely a convenience — it is emotional sustenance.
Ms. Li from Wuhan described it this way: "At every appointment in Bangkok, someone explained everything to me in Chinese. It didn't feel like a medical procedure — it felt like someone was walking a difficult journey alongside you."
Transparent Medical Decision-Making
One of AddBaby's core principles is "ensuring patients truly understand their own treatment plan." Every decision — why mini-IVF rather than standard stimulation, why ERA rather than direct transfer, why freeze-all rather than fresh transfer — is accompanied by clear medical rationale, presented in patient-accessible language.
"In China I never knew why the doctor was doing what they were doing — I just followed instructions. At AddBaby, every time I asked why, they gave me a real answer." — Mr. Zhang, patient from Beijing
Not Giving Up After Failure: Analyzing Causes, Adjusting Protocols
Multiple patients in the cases above came to AddBaby after repeated failures elsewhere. AddBaby's approach: systematically analyze the reasons for failure rather than simply repeating the previous protocol. For patients with recurrent failure, AddBaby conducts a comprehensive "failure cause assessment panel" including ERA, immunological factor testing, endometrial thickness and blood flow evaluation, and sperm DNA fragmentation analysis — identifying the overlooked element and building a targeted protocol.
See our AddBaby IVF complete process guide to learn how we systematically address recurrent failure.
Ongoing Follow-Up After Success
AddBaby's service does not end with a successful transfer. After confirmed pregnancy, coordinators provide regular check-ins throughout the pregnancy, assistance with prenatal care recommendations, coordination of medical handover for delivery back home, and congratulatory follow-up after birth.
"Seeing these success stories is our greatest professional reward." — AddBaby Chief Coordinator
Frequently Asked Questions
Q1: Are these cases real?
Yes, all cases are based on real patient experiences at AddBaby. Before publication, written consent was obtained from each patient, and identifiable personal information (specific names, hometowns, employers, etc.) has been anonymized to protect patient privacy. All medical data (stimulation protocols, egg counts, test results, etc.) are sourced from AddBaby's clinical records.
Q2: My situation is different from these cases — can AddBaby still help me?
Every patient's situation is unique, and these cases are intended as reference points, not templates. AddBaby's value lies not in replicating a successful case protocol, but in finding the most appropriate individualized plan through comprehensive assessment. Whether your challenges involve advanced age, low ovarian reserve, male factor, immune issues, uterine abnormalities, or unexplained recurrent failure, we recommend beginning with an online consultation so our specialists can understand your specific situation.
Q3: What is AddBaby's overall success rate?
Success rates are influenced by many factors including patient age, diagnosis, and embryo quality — a single number cannot capture this complexity. At AddBaby's top partner hospitals in Thailand, for patients under 35 using their own eggs, the success rate per euploid embryo transfer is approximately 60–70%; for donor egg patients, success rates are typically higher (>70%). We are committed to transparent data disclosure and welcome direct questions about specific figures during consultation.
Q4: What percentage of patients succeed on the first try?
This depends on embryo quality (whether PGT-A euploid embryos were used), patient age, and uterine condition. For PGT-A euploid embryo transfers, first-transfer success rates are approximately 50–65%; for unscreened embryos, first-transfer success rates are typically 30–50%. Overall, most patients achieve successful pregnancy within 2–3 egg retrieval and transfer cycles.
Q5: Can I communicate directly with these successful patients?
To protect patient privacy, AddBaby does not facilitate direct patient-to-patient contact. However, AddBaby manages a curated WeChat patient community where many former patients voluntarily share their experiences, allowing you to exchange genuine insights. Please apply through AddBaby's official channels to join.
