Does Prince of Wales Hospital Offer PGT? Analysis of PGT Services in Hong Kong Public Hospitals

Opening: A Real Consultation Scenario

📍 A 38-year-old woman, due to a family history of carrying a balanced chromosomal translocation, plans to conceive through PGT-SR. She has completed basic infertility workups at Prince of Wales Hospital and was informed that the hospital does not offer PGT services, with a recommendation to refer to a private fertility center. The patient's question: Does Prince of Wales Hospital actually have PGT technology? If so, what is the actual pathway?

1. Direct Answer: Prince of Wales Hospital Does Not Offer PGT Services

Prince of Wales Hospital is a major public teaching hospital in Hong Kong, affiliated with The Chinese University of Hong Kong. Its Reproductive Medicine Centre provides the following assisted reproductive technology services:

• IVF (Conventional In Vitro Fertilization): For tubal factor infertility, endometriosis, unexplained infertility, etc.
• ICSI (Intracytoplasmic Sperm Injection): For severe oligoasthenoteratozoospermia, previous IVF fertilization failure, etc.
• IUI (Intrauterine Insemination), ovulation induction, basic fertility assessment, hysteroscopy, etc.

Services Not Provided: Preimplantation Genetic Testing (PGT), i.e., PGT. Neither PGT-A (aneuploidy screening), PGT-SR (structural rearrangement testing), nor PGT-M (monogenic disease testing) are included in the hospital's routine clinical services.

2. Why Don't Public Hospitals Offer PGT? — Healthcare System and Resource Allocation Logic

Assisted reproductive services in Hong Kong public hospitals are managed by the Hospital Authority, with resource allocation following the principle of "necessity first." Clinically, PGT is considered an elective technology rather than a basic treatment for infertility, and therefore is not included in the routine service package of public hospitals. Specific reasons include:

• Technical Threshold: PGT requires embryo biopsy, whole genome amplification, high-throughput sequencing or genetic analysis, demanding significantly higher laboratory hardware and personnel qualifications than routine IVF.
• Genetic Counseling Needs: PGT must be accompanied by professional genetic counseling to assess indications, testing scope, and ethical issues. Genetic counseling resources within the public system are limited.
• Cost and Charges: Public hospital services are provided at standard fees. The high cost of PGT testing cannot be covered within the existing fee framework.
• Waiting Time: The waiting cycle for public IVF is typically 12-24 months. Adding PGT would further prolong the wait and is not suitable for urgent genetic needs.

From a clinical decision-making perspective, when a patient at Prince of Wales Hospital presents with PGT indications, the reproductive specialist usually makes a genetic counseling referral and advises the patient to complete the subsequent cycle at a private center with PGT qualifications. A clear referral pathway exists between public hospitals and private centers.

3. The Doctor's Perspective: PGT Decision-Making from a Clinical View

When consulting patients, reproductive specialists at Hong Kong public hospitals assess the need for PGT referral based on the following dimensions:

• Clear Genetic Indications: One or both partners are carriers of chromosomal structural rearrangements (e.g., balanced translocation, Robertsonian translocation), patients or carriers of monogenic diseases, or have a history of giving birth to a child with a genetic disease.
• Repeated Implantation Failure or Recurrent Miscarriage: After excluding maternal factors, if an increased proportion of embryonic chromosomal abnormalities is suspected, PGT-A can be used as a screening tool.
• Advanced Maternal Age (≥38 years): The rate of oocyte aneuploidy increases significantly. PGT-A can improve the efficiency of single embryo transfer, but public hospitals usually do not routinely recommend it, as patients can opt for private services.
• Cases Not Suitable for PGT: Very low ovarian reserve (AMH < 0.5 ng/mL), inability to obtain sufficient oocytes for biopsy, or presence of medical contraindications (e.g., uncontrolled thyroid disease, tumors).

At Prince of Wales Hospital, if a doctor determines that PGT is suitable for a patient, they will provide a referral list but will not perform the procedure directly at the hospital. Patients need to contact the private fertility center themselves and bring their examination reports from the public hospital for coordination.

4. Differences Between Hospitals: Comparison of PGT Services in Hong Kong Public vs. Private Fertility Centers

5. Easily Overlooked Details: Referral Process and Examination Coordination

When transitioning from public to private for PGT, four key details are often overlooked:

• Mutual Recognition of Reports: Reports from Prince of Wales Hospital, such as AMH, FSH, karyotype analysis, and infectious disease screening, are usually accepted by private centers (within validity period). However, some private centers may require certain tests to be repeated (e.g., hysteroscopy, semen analysis), so confirmation in advance is necessary.
• Independence of Genetic Counseling: Genetic counseling and PGT testing plans at private centers may involve additional charges. The cost structure should be clarified before starting the cycle to avoid mid-course additions.
• Embryo Transport and Biopsy Timing: If oocyte retrieval is done at a public hospital and PGT at a private center (rare), the embryo transport agreement and liquid nitrogen transfer qualifications between laboratories must be confirmed. In the vast majority of cases in Hong Kong, the entire cycle is completed directly at the private center.
• Limitations of PGT: PGT cannot detect all genetic diseases, and there are risks such as mosaicism and test failure. Patients need to sign a detailed informed consent form acknowledging residual risks.

6. Common Pitfalls: Cognitive Misconceptions and Wrong Expectations

Based on practitioner observations, patients consulting about "PGT at Prince of Wales Hospital" often have the following common misconceptions:

• Misconception 1: "Public hospitals have comprehensive technology, so they must be able to do PGT." — In reality, the role of Hong Kong public hospitals differs from that in Mainland China; PGT is almost exclusively performed in the private sector.
• Misconception 2: "Do IVF at a public hospital, then find a place to do PGT testing myself." — IVF and PGT require seamless coordination within the same center's laboratory. Performing them separately is technically infeasible (embryo transport involves legal and quality control issues).
• Misconception 3: "PGT guarantees a healthy child." — PGT reduces the risk of genetic diseases but cannot eliminate all risks, and it cannot currently predict polygenic disorders (e.g., autism, schizophrenia).
• Misconception 4: "PGT-A is suitable for all advanced-age women." — For women over 38, PGT-A can improve single transfer efficiency, but only if at least 3-5 blastocysts can be obtained for biopsy. If the egg count is very low, PGT-A may not be cost-effective.

7. Actual Process: Complete Steps for PGT via a Private Center in Hong Kong

If a patient is assessed as suitable for PGT and decides to proceed at a private center, the standard process is as follows:

1. Genetic Counseling and Plan Confirmation: Determine the type of test (PGT-A/SR/M), sign informed consent.
2. Preparatory Tests: Karyotyping for both partners, carrier screening for genetic conditions, AMH, FSH, semen analysis, infectious disease screening, uterine cavity assessment. Some tests can be done at Prince of Wales Hospital and mutually recognized.
3. Controlled Ovarian Stimulation: Individualized protocol based on follicle count and AMH, average 10-12 days.
4. Oocyte Retrieval and Fertilization: ICSI is performed after retrieval to avoid polyspermy interfering with genetic diagnosis.
5. Blastocyst Culture and Biopsy: Culture to day 5-6 blastocyst stage, open a hole in the zona pellucida, and remove 5-10 trophectoderm cells.
6. Embryo Freezing and Testing: Biopsied blastocysts are immediately cryopreserved, and the biopsied cells are sent for testing (NGS platform). Testing takes approximately 2-4 weeks.
7. Genetic Report Interpretation: Interpreted jointly by a genetic counselor and clinician to determine transferable embryos.
8. Frozen Embryo Transfer: Prepare the endometrium using a natural cycle or hormone replacement cycle. Pregnancy test 12-14 days after transfer.
9. Prenatal Diagnosis: After pregnancy, amniocentesis is recommended for confirmation; PGT results should be verified by prenatal diagnosis.

The entire cycle from stimulation to transfer typically takes 2-3 months, with the testing waiting period being about 2-4 weeks.

9. Practitioner Observation: Actual Decision Points for Public-to-Private PGT Referral

In clinical coordination work, it is observed that patients transitioning from Prince of Wales Hospital to private centers for PGT typically go through the following decision steps:

• Step 1: Complete basic fertility assessment and genetic confirmation at the public hospital to clarify PGT indications.
• Step 2: Compare PGT quotes, testing platforms, genetic counseling teams, and doctor experience from 2-3 private centers.
• Step 3: Assess personal ovarian reserve and expected embryo yield — if AMH < 0.5 ng/mL or age > 42, a more conservative estimate of embryo numbers is needed.
• Step 4: Understand the turnaround time for PGT results and the transfer window to arrange time (some patients may need to take 2-3 months off).
• Step 5: Sign informed consent, clarifying the plan in case of test failure or no transferable embryos (e.g., repeat oocyte retrieval, consider egg donation).

A real clinical scenario: A 35-year-old woman, whose husband is a carrier of a balanced translocation, completed karyotype analysis and genetic counseling at Prince of Wales Hospital, was referred to a private center, ultimately obtained 3 normal embryos, achieved pregnancy after transfer, and the prenatal diagnosis results were consistent with PGT. This pathway is a typical model of public-private collaboration in Hong Kong.

10. Time Planning Reminder

If you decide to proceed with PGT through a private center, the timeline is as follows:

• Months 1-2: Complete all basic tests + genetic counseling + referral at the public hospital (can be done in parallel).
• Month 3: Consultation at the private center + cycle plan confirmation + signing consent forms.
• Month 4: Ovarian stimulation + oocyte retrieval + biopsy + freezing (approx. 2 weeks) → Testing wait 2-4 weeks.
• Months 5-6: Genetic report interpretation + frozen embryo transfer preparation + transfer procedure.
• 2 weeks after transfer: Pregnancy test; 8-10 weeks after transfer: Ultrasound to confirm fetal heartbeat; 16-18 weeks gestation: Amniocentesis for confirmation.

The entire process from initiation to pregnancy confirmation generally takes 5-7 months. If no embryos are available for transfer in the first cycle, repeated oocyte retrieval will be needed, extending the time accordingly.
