How to Check Hong Kong Hospital Success Rates: Official Channels & Data Interpretation Methods

Opening: Real Consultation Scenario

Real Consultation Scenario — Last week, a 42-year-old patient with an AMH of 0.8 came in holding a promotional flyer from a Hong Kong fertility center and asked: “It says the live birth rate is 58%. Do I have the same probability?” This is one of the most common misconceptions I encounter in the clinic. Today, starting from this question, I will systematically explain how to correctly query and interpret success rate data from Hong Kong hospitals.

============================================ Module A: Direct Answer to the Question ============================================

1. Three Core Channels for Querying Hong Kong Hospital Success Rates

To obtain authentic and reliable success rate data, you must bypass advertising and directly use the following three channels. Each channel has its own focus, and cross-verification is recommended.

1.1 Hong Kong Human Reproductive Technology Authority (HTA) Annual Report

OfficialStatutory The HTA is the statutory regulatory body for assisted reproduction in Hong Kong. All licensed fertility centers must submit treatment data annually. The HTA publishes the "Annual Report on Assisted Reproductive Technology Treatments in Hong Kong," which includes core indicators such as the number of treatment cycles, clinical pregnancy rates, and live birth rates for each center and age group. This is currently the most authoritative and unbiased data source.

• Coverage: All public and private fertility centers licensed by the HTA.
• Data Dimensions: Stratified by age (<35, 35-37, 38-39, 40-42, ≥43), distinguishing between fresh embryo transfer and frozen embryo transfer.
• Access Method: PDF versions are available for download on the HTA official website, typically updated annually (with a lag of about 12-18 months).

1.2 Annual Data Published on Individual Fertility Center Websites

Major fertility centers in Hong Kong (such as the Reproductive Medicine Centre of Hong Kong Sanatorium & Hospital, Fertility Centre of Union Hospital, Assisted Reproduction Unit of Queen Mary Hospital, and Reproductive Centre of Prince of Wales Hospital) publish their own data on their websites or in annual reports. However, statistical definitions, patient selection criteria, and data presentation methods may vary between centers.

• Advantages: Data is updated more promptly, and some centers provide breakdowns by embryo type (cleavage stage/blastocyst) and transfer strategy (single/multiple embryo transfer).
• Limitations: There is a possibility of "selective reporting"—some centers may only display favorable data and conceal data for younger or high-risk groups.

1.3 Third-Party Medical Information Platforms and Patient Communities

Some international medical platforms (such as IVF Worldwide, Society for Reproductive Medicine) aggregate data from various centers. Additionally, real experiences shared on local Hong Kong patient forums and WhatsApp groups can serve as references, but be aware of sample bias and subjective factors.

============================================ Module L: Interpretation of Key Indicators ============================================

2. Five Key Indicators to Focus on When Interpreting Success Rate Data

Many patients only look at a single "success rate" number, but evaluating assisted reproduction outcomes requires multidimensional indicators. The following five indicators are what doctors and professionals truly focus on.

Indicator Name	Definition	Clinical Significance
Clinical Pregnancy Rate	Number of cycles with ultrasound-confirmed gestational sac ÷ Total number of transfer cycles	Reflects embryo implantation ability, but cannot distinguish whether development continues.
Live Birth Rate	Number of cycles resulting in a live birth ÷ Total number of transfer cycles	The most robust outcome indicator and the data patients should focus on most.
Cumulative Live Birth Rate	Probability of a live birth from one oocyte retrieval cycle (including all subsequent frozen embryo transfers)	Reflects the ultimate success rate of the entire treatment cycle, more comprehensive than single transfer data.
Embryo Implantation Rate	Number of gestational sacs ÷ Total number of embryos transferred	A sensitive indicator for assessing embryo quality and laboratory culture standards.
Live Birth Rate per Oocyte Retrieval Cycle	Number of live birth cycles ÷ Total number of oocyte retrieval cycles	Includes cycles without transfer, providing a more realistic probability of success from the start.

Core When querying Hong Kong hospital data, prioritize "live birth rate" and "cumulative live birth rate" over "clinical pregnancy rate." The "pregnancy rate" advertised by some centers may include early biochemical pregnancies, which can be significantly higher than the live birth rate.

============================================ Module C: How Doctors Interpret Data ============================================

3. How Doctors Interpret Success Rate Data

As a reproductive specialist, when evaluating a center's data, I don't just look at the highest value. Instead, I focus on the following five dimensions:

1. Completeness of Age-Stratified Data — If only overall data is provided without age stratification, it may indicate that data from younger groups is inflating the overall figure.
2. Adequacy of Sample Size — Centers with fewer than 200 cycles per year have highly variable data and insufficient statistical stability.
3. Patient Selection Criteria — Are complex cases such as diminished ovarian reserve or recurrent implantation failure excluded? Data from "selected patients" can differ significantly from "real-world" data.
4. Single Embryo Transfer (SET) Rate — The live birth rate for SET is usually lower than for multiple embryo transfer (MET), but it is safer. If a center has a high MET rate, the live birth rate may be artificially inflated, along with an increased risk of multiple pregnancies.
5. Data Year and Trends — Data from a single year may be coincidental. Look at trends over at least three consecutive years.

============================================ Module F: Differences Between Hospitals ============================================

4. Public vs. Private Hospitals: Reasons Behind Data Differences

There are objective differences in success rate data between public fertility centers (e.g., Queen Mary Hospital, Prince of Wales Hospital) and private centers (e.g., Hong Kong Sanatorium & Hospital, Union Hospital, Canossa Hospital) in Hong Kong. However, the reasons are complex and cannot be simply attributed to "technical quality."

Comparison Dimension	Public Hospitals	Private Hospitals
Average Patient Age	Higher (approx. 37-39 years)	Relatively lower (approx. 35-37 years)
Patient Selection	Accept complex cases (diminished ovarian reserve, recurrent failure, advanced age)	Some selection; some complex cases referred to public hospitals
Embryo Transfer Strategy	Strict single embryo transfer (policy constraint)	Single or multiple embryo transfer, chosen based on patient condition
Reported Data Definition	Usually report according to HTA standards; data is conservative	Some centers use more favorable statistical definitions
Live Birth Rate (under 35)	Approx. 45-55%	Approx. 50-65%
Live Birth Rate (over 40)	Approx. 10-20%	Approx. 15-25%

Important "Lower" data from public hospitals does not mean inferior technology; it reflects a more complex patient population, higher average age, and more conservative transfer strategies. When comparing different centers, it is essential to adjust for age and patient selection factors to draw meaningful conclusions.

============================================ Module G: Most Easily Overlooked Details ============================================

5. Five Most Easily Overlooked Details

• Differences in Statistical Definitions: Some centers report "live birth rate per transfer cycle," while others report "cumulative live birth rate per oocyte retrieval cycle." The former is numerically higher, but the latter is more clinically meaningful.
• Embryo Culture Strategy: Centers that culture blastocysts have a higher live birth rate per single transfer, but some patients may have no blastocysts for transfer. Check both "blastocyst formation rate" and "cycle cancellation rate."
• Impact of PGT (Preimplantation Genetic Testing): Centers performing PGT select chromosomally normal embryos, leading to a higher live birth rate after transfer. However, embryo loss due to testing over the entire cycle must also be considered.
• Data Year: Assisted reproductive technology advances every year. Data from 2021 may differ significantly from 2024 data. Try to refer to data from the most recent 2-3 years.
• Match with Patient's Own Condition: Even at the same center, success rates vary greatly depending on age, ovarian reserve, and cause of infertility. The "overall success rate" published by a center has limited reference value for an individual.

============================================ Module H: Common Pitfalls ============================================

6. Four Common Misconceptions to Avoid

1. Attracted by "High Success Rates," Ignoring Your Own Condition — A center's published 65% live birth rate may come from low-risk patients under 35 with normal AMH. It has very little reference value for patients over 40.
2. Only Looking at "Clinical Pregnancy Rate," Ignoring "Live Birth Rate" — The clinical pregnancy rate includes cycles with early miscarriage and can be 10-20 percentage points higher than the live birth rate.
3. Blindly Trusting "Success Rate Rankings" — There is no official ranking of fertility centers published in Hong Kong. Any "ranking" is based on specific weightings and may have commercial purposes.
4. Ignoring the "Cycle Cancellation Rate" — To boost live birth rates, some centers tend to cancel transfer cycles with unfavorable conditions (e.g., thin endometrium, high progesterone). A high cancellation rate can inflate the apparent live birth rate, but patients may need multiple retrievals to achieve one transfer.

============================================ Module Q: Frequently Asked Questions ============================================

7. Frequently Asked Questions

Q1: Which hospital in Hong Kong has the highest success rate?

There is no fixed answer. Outcomes may differ for patients of different ages and causes at different centers. It is recommended to check the data for your specific age group in the HTA report rather than looking only at overall data.

Q2: How big is the success rate difference between public and private hospitals?

For low-risk patients under 35, the difference is about 5-10 percentage points. For high-risk patients over 40, the difference narrows to 3-5 percentage points. However, public hospitals have a higher average patient age and more complex cases, making direct comparison unfair.

Q3: Why is the data in the HTA report lower than on hospital websites?

The HTA report uses standard statistical definitions, includes all data from all licensed centers, and has no patient selection. Hospital websites may only show data for "favorable groups" or use different statistical definitions. The gap between the two can, to some extent, reflect "data transparency."

Q4: Can I directly apply a center's published success rate using my own AMH and age?

No, you cannot directly apply it. The published data is a group statistical result. Individual outcomes are influenced by multiple factors, including embryo chromosomal normality, uterine environment, endocrine status, and lifestyle. Use the data as a reference range, not a precise prediction.

Q5: What key questions should I ask a hospital when checking success rates?

It is recommended to proactively ask during consultation: ① Live birth rates for each age group over the past 3 years; ② Cumulative live birth rate per oocyte retrieval cycle; ③ Cycle cancellation rate; ④ Single embryo transfer rate; ⑤ Average patient age and median AMH. Centers that can clearly answer these questions with reasonable data are generally more trustworthy.

============================================ Module R: Practitioner's Observation ============================================

8. Practitioner's Observation: The Real "Strength Indicators" Behind the Data

With over 10 years of experience in the assisted reproduction field, I believe the following four dimensions reflecting a center's true strength are more noteworthy than the "success rate number":

• Embryology Lab Quality Control System — The lab is the "heart" of a fertility center. A stable culture environment, a highly skilled team of embryologists, and comprehensive quality control records are essential for good outcomes. This information is usually not public, but can be indirectly assessed by whether the center has international quality control certifications (e.g., ISO, UK NEQAS).
• Multidisciplinary Collaboration Capability — Does the fertility center have teams for reproductive endocrinology, reproductive surgery, genetic counseling, and psychological support? Complex cases (e.g., recurrent implantation failure, recurrent miscarriage) require multidisciplinary collaboration, not just maximizing embryo numbers.
• Data Transparency and Patient Education Level — Centers willing to proactively explain data definitions to patients and provide personalized prognosis assessments are often more confident and responsible.
• Degree of Individualization in Treatment Strategy — Does the center tailor ovulation induction protocols and transfer strategies based on the patient's age, ovarian reserve, and medical history, rather than using a "one-size-fits-all" standardized process?
