Fact-checked via 4-step process— how we build this report

01Primary Source Collection

Data aggregated from peer-reviewed journals, government agencies, and professional bodies with disclosed methodology and sample sizes.

02Editorial Curation

Human editors review all data points, excluding sources lacking proper methodology, sample size disclosures, or older than 10 years without replication.

03AI-Powered Verification

Each statistic independently verified via reproduction analysis, cross-referencing against independent databases, and synthetic population simulation.

04Human Cross-Check

Final human editorial review of all AI-verified statistics. Statistics failing independent corroboration are excluded regardless of how widely cited they are.

Statistics that fail independent corroboration are excluded.

Miscarriage is often described in general terms, but the statistics behind it are anything but simple. In 2025, the reported rates across different studies still vary widely, showing how much estimates can shift depending on how pregnancy loss is counted. By comparing those figures side by side, the real picture of risk and timing becomes clearer, and it raises questions many people never see in a single number.

Causes Interpretation

It seems our reproductive system is an incredibly complex project where, for all the meticulous planning we can attempt, the blueprint itself can have a critical typo, the construction site might have an unforeseen flaw, the on-site security can get confused, and sometimes, despite checking every box, the whole thing just quietly shuts down without a clear memo on why.
