Comparison of Assisted Reproduction Hospital Sizes in China: Annual IVF Cycles and Team Configuration

Real consultation scenario opening

📋 Real consultation scenario · Perspective of a consultant with 10 years of experience

Last month, a 38-year-old patient with an AMH of 0.9 asked me a question:
“I see some reproductive centers claim to perform over 40,000 cycles a year, while others say they only do a little over 2,000. Should I choose a large-scale or a small-scale one? Does a larger scale mean it is better?”
This question is not an isolated case. Almost every week, patients compare promotional materials from two hospitals, torn between a large center with tens of thousands of annual cycles and a medium-sized center with two to three thousand annual cycles, struggling to decide.

This article focuses on the “Comparison of Assisted Reproduction Hospital Sizes in China.” It does not rank or recommend, but simply clarifies the indicators, logic, and suitable populations behind the scale.

I. What is the Core Indicator of Scale?

The most rigid indicator for measuring the scale of a reproductive center is the annual number of IVF cycles (i.e., annual egg retrieval cycles), followed by the annual number of transfer cycles and the annual number of live births. Additionally, the size of the doctor team, the area of the embryology laboratory and the configuration of technical staff, and whether there is an independent reproductive medicine building are also reference dimensions related to scale.

According to industry-standard classifications (referencing data from major domestic reproductive centers):

Note: The annual cycle count usually refers to egg retrieval cycles, not transfer cycles. Some institutions may blur these two figures in their promotions, so it is necessary to distinguish them.

II. How Do Doctors View the Relationship Between Scale and Quality?

Among reproductive doctors, there is a fairly consistent view on scale: Scale is one indicator of experience accumulation, but not a guarantee of quality.

From a medical perspective, large centers handle a large number of cases each year, accumulating more clinical experience, especially in complex cases such as poor ovarian response, recurrent implantation failure, and advanced age. Their laboratory embryologists are also more skilled in handling various types of semen samples and egg morphologies. However, a large scale also means a high patient volume, which may compress the consultation time for each patient, potentially reducing the doctor's attention to individual details.

A doctor who has worked for 12 years in a tertiary hospital reproductive center once told me: “Our center performs over 10,000 cycles a year, but the time each patient gets with the doctor is actually limited. In contrast, doctors in medium-sized centers have more energy to focus on details.” This is not to deny large centers, but to remind patients: There is a balance between scale and individualization.

III. Scale Characteristics of Public Tertiary Hospitals vs. Private Reproductive Centers

Domestic reproductive centers are divided by institutional nature into public hospital reproductive centers and private/foreign-funded reproductive centers, with significant differences in scale performance:

It is important to note that although private centers have fewer cycles, some may have specific advantages in particular technologies (such as PGT, egg freezing, third-party assisted reproduction). A small scale does not necessarily mean a low technical level.

IV. Three Details Most Easily Overlooked Behind the Scale

4.1 The Size of the Lab Team is More Critical Than the Size of the Doctor Team

The embryology laboratory is the “heart” of a reproductive center. A large center's lab typically employs 10–30 embryologists responsible for egg retrieval, ICSI, embryo culture, freezing, and thawing. The stability of the lab personnel, the number of incubators, and the quality control system directly determine embryo outcomes, but this information is rarely mentioned in promotional materials. Patients can ask: “How many full-time embryologists does the lab have? Are the incubators individual or shared?”

4.2 Annual Cycle Counts Include “In-house Cycles” and “Referral Cycles”

The cycle numbers published by some centers include referral specimens from partner institutions (e.g., eggs retrieved elsewhere but sent to the center for culture), which are not directly treated patients of the center. Looking only at the total number may overestimate the actual patient capacity. It is advisable to distinguish between “in-house egg retrieval cycles” and “total cycles processed.”

4.3 The Larger the Scale, the Stronger the Standardized Process, and the Smaller the Space for Individualization

To improve efficiency, large centers typically adopt standardized ovarian stimulation protocols and fixed monitoring procedures. For atypical cases (such as specific genetic diseases, rare endocrine disorders, or multiple previous failures), the standard protocol may not be the optimal choice. Medium-sized or small centers are more likely to customize plans for such patients.

V. Three Common Cognitive Misconceptions to Avoid

• Misconception 1: Large scale = High success rate
  Clinical pregnancy rates are greatly influenced by patient age, etiology, and ovarian function. The patient composition varies greatly between centers, making direct comparison of success rates meaningless. Large centers may receive more advanced-age and complex cases, which can lower their overall success rate, but this does not indicate inferior technical skill.
• Misconception 2: Small scale = Unregulated
  All institutions in China that perform assisted reproductive technology must be approved by the National Health Commission. Regardless of size, they all adhere to uniform technical standards and ethical norms. Small centers are often “small but specialized” and may have advantages in specific areas (such as ovarian function preservation or fertility preservation).
• Misconception 3: Only look at cycle numbers, not team stability
  Some centers experience rapid growth in cycle numbers, but high turnover of core doctors and embryologists can negatively impact the continuity of clinical quality. Team stability is more noteworthy than scale growth.

VI. Observations from a Consultant with 10 Years of Experience

Over the years, I have handled consultations for thousands of patients and accompanied them to many domestic reproductive centers. A relatively clear trend is: Patients' attitudes towards scale are shifting from 'bigger is better' to 'what suits me best is best.'

Specifically, the following three groups of people have different sensitivities to scale:

Additionally, there is another easily overlooked factor: geographic accessibility. During ovarian stimulation, frequent hospital visits for monitoring are required (approximately 6–10 visits). If the center is very large but far away, the physical strain of travel may offset the technical advantages of scale. In the past two years, more and more patients have chosen medium-sized centers within their province or neighboring provinces for this reason.

VII. Special Situations: When Scale Meets Policy Restrictions

China implements an access system for assisted reproduction institutions. As of the end of 2024, there are approximately 550 medical institutions approved to perform assisted reproductive technology nationwide, of which less than 15% can perform third-generation IVF (PGT). This means:

• Patients who want PGT are inherently limited to large centers (because PGT requires extremely high standards for labs and genetic teams);
• If only first or second-generation IVF is needed, medium-sized centers are fully capable of providing equivalent technical proficiency, and there is no need to deliberately pursue scale.

Furthermore, some provinces have “regional planning” restrictions on reproductive centers, meaning a city may only have 2–3 approved institutions. In such cases, differences in scale reflect more the hospital's own development level rather than differences in technical access.
