1. Four Main Feasible Paths After IVF Failure in Hong Kong

IVF failure is not an endpoint but a point requiring reassessment. Based on the cause of failure, age, ovarian reserve, financial conditions, and legal restrictions, the subsequent paths are mainly divided into the following four categories:

These four paths are not mutually exclusive. Some patients may first try adjusting the plan, and if the results are not satisfactory, then consider changing centers or moving to other regions. The key is: Before choosing, first figure out the cause of the failure.

2. Systematic Analysis of the Cause of Failure is the First Step

Blindly changing plans or centers without a clear cause still carries a high likelihood of failure. When evaluating the cause of failure, reproductive physicians usually start from the following four dimensions:

2.1 Embryo Factors

Embryo chromosomal aneuploidy is the main cause of implantation failure and miscarriage, especially when the woman is ≥38 years old, where the proportion of euploid embryos significantly decreases. Additionally, the embryo’s developmental kinetics, fragmentation degree, and blastocyst formation ability directly affect the outcome.

• Examination methods: PGT-A (preimplantation genetic testing for aneuploidy), time-lapse imaging culture system, embryo morphology assessment.
• Easily overlooked point: Even embryos with a good morphological grade may have chromosomal abnormalities. For patients with recurrent failure, PGT-A has significant reference value.

2.2 Uterine Factors

Insufficient endometrial receptivity is another key variable. Intrauterine adhesions, endometrial polyps, chronic endometritis, uterine fibroids (especially submucosal type), and endometrial microbiota imbalance can all affect embryo implantation.

• Examination methods: Hysteroscopy (gold standard), endometrial receptivity array (ERA), endometrial microbiota analysis, CD138 immunohistochemistry (for diagnosing chronic endometritis).
• Easily overlooked point: Routine transvaginal ultrasound is not sensitive to small endometrial polyps or adhesions; hysteroscopy is a necessary investigation.

2.3 Maternal Factors

Endocrine abnormalities (hypothyroidism, hyperprolactinemia, luteal phase deficiency), metabolic issues (insulin resistance, vitamin D deficiency), immune disorders (antiphospholipid syndrome, abnormal NK cell activity, positive thyroid antibodies) can all affect egg quality, embryo development, and implantation.

• Examination methods: Thyroid function, antiphospholipid antibody panel, NK cell activity, homocysteine, 25-hydroxyvitamin D, glucose tolerance test, etc.
• Easily overlooked point: Male factors are also a key link outside of “maternal factors”—elevated sperm DNA fragmentation index (DFI) significantly affects embryo developmental potential, but routine semen analysis cannot reflect this.

2.4 Laboratory Factors

Culture conditions (culture media batch, oxygen concentration, temperature stability), operational techniques (ICSI, assisted hatching, biopsy techniques), and the experience of laboratory personnel all affect embryo development.

• Evaluation method: Understand the center’s quality control data (e.g., fertilization rate, blastocyst formation rate, euploidy rate) and compare with industry benchmarks.
• Significance of changing centers: If lab quality is suspected, switching to a center with better quality control data is a reasonable choice.

3. Applicable Conditions and Specific Procedures for Different Paths

3.1 Adjust Plan at Original Center

Applicable conditions: There is a clear, correctable cause of failure; the patient trusts the original center’s treatment quality; financially able to attempt another 1–2 cycles.

Specific procedures:

• Have a formal discussion about the cause of failure with the primary physician, reviewing the complete cycle records.
• Supplement missing examinations: e.g., hysteroscopy, endometrial receptivity testing, sperm DNA fragmentation index, complete immune panel, etc.
• Adjust the plan based on results: change ovarian stimulation protocol (e.g., from long protocol to antagonist or mild stimulation), adjust trigger medication (hCG vs. GnRH-a), switch to ICSI, assisted hatching, or PGT-A.
• Allow 1–3 months for physical and mental adjustment before the next cycle.

3.2 Change Fertility Center

Applicable conditions: Lack of confidence in the original center’s lab quality or treatment strategy; multiple plans have been tried at the original center with failure; desire for a different expert opinion.

Specific procedures:

• Collect all medical records from the original center (including stimulation records, embryo photos, culture records, transfer records, lab quality control data).
• Choose 1–2 new centers for an initial consultation, bringing all documents.
• The new center will reassess: review previous test results, supplement missing items, and formulate a new plan.
• Required for registration: identification documents, previous medical records, relevant test reports, marriage certificate (required by some centers).
• Before starting a new cycle, it is recommended to fully discuss the cause of failure analysis and treatment logic with the primary physician.

Note: Changing centers does not automatically increase the success rate. The new center’s lab quality and treatment approach are core variables; it is recommended to focus on its blastocyst formation rate, euploidy rate, and clinical outcomes for similar cases.

3.3 Egg Donation / Embryo Donation

Applicable conditions: Ovarian reserve near depletion (AMH < 0.5 ng/mL), advanced age (≥44 years), recurrent poor embryo quality (no transferable embryos or only low-quality embryos for 2 consecutive cycles), or genetic diseases making it unsuitable to use own eggs.

Specific procedures:

• Medical evaluation: confirm suitability for receiving donation (age, uterine condition, overall health).
• Legal consultation: understand the legal regulations regarding egg donation in Hong Kong and the target region (Hong Kong allows egg donation, but sources are limited; some countries/regions have more established donation systems).
• Choose donation source: known donor (e.g., relative or friend) or anonymous donor (through a fertility center or egg bank).
• Donor screening: carrier screening for genetic diseases, chromosome karyotype, infectious disease screening, psychological evaluation.
• Simultaneously prepare the recipient’s endometrium: use an artificial or natural cycle to prepare the endometrium, and transfer after embryos are formed from the donated eggs.

Success rate reference: The live birth rate using donated eggs is generally high (approximately 50%–60% per single transfer), mainly influenced by the recipient’s age and uterine condition, not the donor’s age (donors are typically young and screened).

3.4 Move to Other Regions

Applicable conditions: Need for a different legal environment (e.g., Hong Kong does not allow certain genetic tests or donation methods), desire for different medical resources, or need for more flexible treatment plans (e.g., natural cycle, mild stimulation).

Common destinations and characteristics:

Process for moving to other regions: Understand target region’s legal policies → Choose a medical institution → Remote video consultation → Prepare medical documents and visa → Travel for initial consultation → Start the cycle.

Document preparation: Passport (valid for >6 months), marriage certificate (if applicable), translated copies of previous medical records, visa (according to destination requirements). It is recommended to start preparation 2–3 months in advance.

4. Key Details Easily Overlooked

• Chromosome karyotype analysis: Many patients only check the embryo’s chromosomes but overlook the couple’s karyotype. The detection rate of cryptic balanced translocations in the recurrent failure population is about 3%–5%, which is an important cause of recurrent miscarriage and abnormal embryo development.
• Sperm DNA fragmentation index (DFI): When DFI > 30%, even if routine semen analysis is normal, it significantly affects blastocyst formation and implantation rates. Elevated DFI is associated with oxidative stress, varicocele, smoking, high temperature environments, etc.
• Chronic endometritis (CE): The incidence in the infertile population is about 30%–40%, but it cannot be diagnosed by routine ultrasound. Hysteroscopy may reveal endometrial congestion, edema, and small polypoid hyperplasia; diagnosis requires CD138 immunohistochemical staining.
• Vitamin D levels: Vitamin D deficiency is associated with diminished ovarian function, embryo implantation failure, and pregnancy complications. Among recurrent failure patients, the proportion with insufficient vitamin D exceeds 60%.
• Thyroid autoantibodies: Even with normal thyroid function, positive TPO-Ab or Tg-Ab is associated with recurrent implantation failure and may affect the endometrial immune microenvironment.

5. Common Decision-Making Misconceptions

• Misconception 1: Immediately change centers after failure. Without analyzing the cause of failure, changing centers may just mean repeating the same mistakes in a different place. It is recommended to conduct a systematic evaluation first, then decide whether to change.
• Misconception 2: Believing that using donated eggs means “giving up.” From a medical perspective, using donated eggs is an efficient solution, especially for patients with ovarian failure or recurrent poor embryo quality. It does not mean “failure,” but rather another reasonable path.
• Misconception 3: Blindly pursuing centers with high success rates. Each center’s success rate is greatly influenced by the characteristics of its patient population; direct numerical comparison is meaningless. Focus on the center’s specific data for cases similar to yours (age, diagnosis, number of previous cycles).
• Misconception 4: Ignoring psychological and lifestyle factors. Persistent stress, anxiety, lack of sleep, and abnormal weight (underweight or overweight) can affect treatment outcomes through endocrine and immune pathways. Taking time for physical and mental adjustment between attempts is not a waste of time, but part of the treatment.
