Data & Research

How we verify, interpret, and publish fertility data—for transparency and understanding.

We don’t collect data to market; we collect it to clarify.

What data we use

We source fertility statistics from U.S. public databases to ensure every comparison is verifiable.

Primary sources:

  • CDC ART Success Rates Database (latest: 2023 cycle)
  • SART Clinic Reports (participating clinics)
  • Verified clinic disclosures and coordinator confirmations

These data form the foundation of every clinic profile on BetterFreeze.

How we process data

Every dataset goes through a three-step process to ensure accuracy and clarity:

Verification

Cross-checked against CDC/SART records and clinic disclosures.

Normalization

Aligned by comparable indicators (e.g., success rate per embryo transfer).

Annotation

Reviewed by clinicians with notes that explain what the numbers mean.

This process turns raw data into context patients can actually understand.

Why we publish these data

Transparency is not our goal—it’s our method.

By showing how outcomes differ by clinic or program, we help patients understand the system itself.

We believe understanding is the first step toward freedom of choice in fertility care.

Example: U.S. national IVF outcomes (2023)
