1. Direct Answer: Can Gleneagles Hong Kong Hospital Perform Third-Generation IVF?

The Reproductive Medicine Centre of Gleneagles Hong Kong Hospital has the technical foundation to perform Preimplantation Genetic Testing (PGT, i.e., third-generation IVF), including an embryo culture laboratory, a genetics collaboration platform, and an experienced reproductive medicine team. However, whether it can be implemented depends on whether the patient's medical indications comply with the provisions of Hong Kong's Human Reproductive Technology Ordinance (Cap. 561) and the current scope of the hospital's genetics laboratory registration. Patients can only determine whether to enter the PGT process after evaluation by a reproductive medicine specialist.

2. Doctor's Perspective: Indications and Necessity of PGT

From a reproductive medicine perspective, the core value of third-generation IVF lies in reducing the risk of genetic disease transmission and improving embryo implantation efficiency, but it is not a routine method to increase live birth rates. The Hong Kong reproductive medicine community adopts a cautious approach to PGT, requiring clear medical indications:

• Monogenic Diseases: Such as carriers of known pathogenic genes for cystic fibrosis, haemophilia, spinal muscular atrophy (SMA), etc.
• Chromosomal Structural Abnormalities: Balanced translocations, Robertsonian translocations, inversions, etc., leading to recurrent miscarriage or increased risk of embryonic aneuploidy.
• Repeated Implantation Failure: ≥3 transfers of good-quality embryos without implantation, after excluding uterine cavity factors.
• Advanced Age (≥38 years) with Sufficient Egg Count: PGT-A (aneuploidy screening) can reduce miscarriage rates, but decisions must be made based on embryo quantity.

During the outpatient consultation, the doctor will focus on assessing: whether the genetic risk is clear, whether there are a sufficient number of blastocysts for biopsy, and whether the patient's ovarian reserve supports another stimulation cycle. If the indications are unclear, the doctor usually recommends trying conventional IVF or Intracytoplasmic Sperm Injection (ICSI) first.

3. Actual Process: Steps to Complete Third-Generation IVF at Gleneagles Hong Kong Hospital

The following is the standard pathway for the PGT process at Gleneagles Hong Kong Hospital. Each step may be adjusted slightly based on individual circumstances:

4. Timeline: How Long Does It Take from Initial Consultation to Transfer?

In the absence of special circumstances (such as poor ovarian response, embryo developmental arrest, abnormal test results), a complete PGT cycle takes approximately 3–5 months. Specific milestones:

• Initial consultation to start of stimulation: 1–2 months (including genetic counselling, tests, protocol formulation)
• Stimulation to obtaining test report: approx. 5–6 weeks
• Frozen embryo transfer cycle: 1–1.5 months (endometrial preparation, transfer, pregnancy test)

If both partners need to complete chromosome karyotype analysis or gene verification, the time may extend to more than 6 months. It is recommended to allow sufficient time to avoid the testing cycle affecting the transfer plan.

5. Cost Influencing Factors: Cost Composition of PGT in Hong Kong

Gleneagles Hong Kong Hospital is a private medical institution in Hong Kong. The cost of third-generation IVF is significantly higher than conventional IVF. The main components are as follows:

The total cost is usually between HKD 140,000–240,000, varying depending on the medication protocol, number of biopsied embryos, and type of testing. It is recommended to request a detailed fee schedule from the hospital's finance department before starting and confirm whether subsequent cryopreservation fees are included.

6. Interpretation of Test Indicators: Which Results Affect PGT Decisions?

The following key indicators directly influence the reproductive specialist's judgement on the feasibility of PGT at Gleneagles Hong Kong Hospital:

• AMH ≥ 1.2 ng/mL: Indicates acceptable ovarian reserve with potential to obtain sufficient follicles; when AMH < 0.8 ng/mL, the number of eggs retrieved may be insufficient, reducing the cost-effectiveness of PGT.
• Antral Follicle Count (AFC) ≥ 8: Total number of basal antral follicles in both ovaries, directly related to the number of eggs retrieved.
• Chromosome Karyotype Analysis: Both partners must have a normal karyotype or clearly carry a structural abnormality such as a balanced translocation; unexplained chromosomal polymorphisms usually do not constitute a PGT indication.
• Sperm DNA Fragmentation Rate (DFI) < 30%: High DFI may affect embryo developmental potential; male factors need to be addressed first.
• Previous Embryo Chromosome Results: If there is a history of ≥2 embryonic aneuploidies, the benefit of PGT-A is more clear.

7. Suitable and Unsuitable Populations

Suitable Populations

• Clearly carries a monogenic pathogenic mutation, and the pathogenic gene has been verified by the laboratory.
• One partner is a carrier of a balanced translocation or Robertsonian translocation.
• Repeated implantation failure (≥3 times) after excluding acquired factors such as intrauterine adhesions or endometritis.
• Advanced age (≥38 years) with a history of aneuploidy pregnancy and acceptable ovarian reserve.

Unsuitable Populations

• No clear genetic indication, only requesting PGT to "increase success rate."
• Severely diminished ovarian reserve (AMH < 0.5 ng/mL, AFC < 4), with expected egg retrieval insufficient to support biopsy.
• Untreated conditions such as adenomyosis, intrauterine adhesions, or endometrial polyps; the uterine cavity environment should be treated first.
• One partner has uncontrolled systemic issues such as thyroid dysfunction or autoimmune disease.

8. Frequently Asked Questions

Q1: What materials are needed for third-generation IVF at Gleneagles Hong Kong Hospital?

Provide: ① Identification documents for both partners (travel permit/passport); ② All previous fertility-related examination reports (including surgical records, miscarriage embryo chromosome results); ③ Genetic history information (e.g., genetic test reports, family pedigree); ④ Informed consent form required by Hong Kong's Human Reproductive Technology Ordinance (provided by the hospital).

Q2: How long is the wait for PGT at Gleneagles Hong Kong Hospital?

From the genetic counselling outpatient to embryo transfer, a routine cycle takes about 4–5 months. If chromosome karyotype analysis or gene verification is needed, it may extend to 6–8 months. The hospital assigns a case coordinator for each patient to follow up on progress.

Q3: What if all embryo test results are abnormal?

This is the most undesirable situation in a PGT cycle. If all biopsiable blastocysts are aneuploid or carry pathogenic genes, the doctor will assess whether to adjust the stimulation protocol or consider egg/sperm donation. It is recommended to discuss a "worst-case scenario plan" with the doctor before starting, including whether to accept another stimulation cycle or consider gamete donation.

Q4: What are the legal restrictions on third-generation IVF in Hong Kong?

According to the Human Reproductive Technology Ordinance, PGT is only permitted to avoid serious genetic diseases. Non-medical sex selection or "designer babies" are prohibited. After embryo biopsy, testing must be performed without undue delay. All procedures must be conducted in institutions holding a "Reproductive Technology Centre Licence."

9. Most Easily Overlooked Details

• Genetic counselling must be completed before ovarian stimulation: Gleneagles Hong Kong Hospital requires both partners to attend together and sign the genetic counselling record; otherwise, the PGT process cannot proceed.
• Some genetic tests require 1–2 months of advance verification: If the pathogenic gene locus is unclear, family verification must be completed first, which may delay the start of the cycle.
• Storage period after embryo biopsy and freezing: Hong Kong regulations generally limit embryo cryopreservation to no more than 10 years, requiring periodic renewal of the consent form.
• Relationship between egg count and biopsy success rate: When the number of eggs retrieved is < 6, the probability of forming a biopsiable blastocyst decreases significantly. The doctor may recommend egg accumulation or cancelling the PGT plan.
