Imagine sitting in a doctor’s office, about to make one of the most profound decisions of your life. You’re considering bringing a child into the world through IVF. You sign the forms, trust the white coats, and assume that every technology being used has been vetted, tested, and proven entirely safe over generations.

Except, it hasn’t been.

A massive, 20-year study of over a million children published right in the Journal of the American Medical Association, looked at every child born in Denmark over a sixteen-year span. What did they find? Children conceived using frozen embryo transfers had double the rate of childhood cancer compared to children conceived naturally. The rate jumped from 18 cases per 100,000 up to 41. Rates of pediatric leukemia ran more than twice as high.

Now, ask yourself: how is this procedure actually used in America today?

In 2021, according to the CDC, an astonishing 84% of all U.S. IVF transfers used frozen embryos. The old method using a fresh embryo is now the rare exception. The fertility industry has almost entirely standardized around freezing.

Of course, the experts will immediately tell you to calm down. They’ll point out that the absolute risk of cancer is still low and that’s true, the vast majority of these children will never get cancer. Then they’ll tell you that the Danish study used older freezing protocols from the late 90s and 2000s, and that modern technology is totally different today. But they’re still frozen.

Allow me to raise the obvious question about where is the 20-year safety data for the modern technology we are using right now?
It doesn’t exist. It can’t exist. Children conceived with today’s exact methods won’t have two decades of health outcomes until the 2040s. This means that today’s families are the clinical trial. You are the experiment.

Don’t you think parents should be given these exact numbers before they sign on the dotted line? Shouldn’t people be allowed to ask basic questions about the long-term trade-offs of massive technological interventions without being dismissed?
If informed consent means anything, it has to mean giving parents the full picture because at the end of the day, it’s the child, not the clinic, who carries the risk.

And just in case you’re thinking that this is a one-off anomaly, think again.

According to Google, several large-scale studies have documented similar statistical correlations between assisted reproductive technology (ART), frozen embryo transfer (FET), and elevated childhood cancer risks:

1. The Nordic Cohort Study (PLOS Medicine, 2022)
   Scope: Tracked over 7.9 million children born across four Nordic countries (Denmark, Finland, Norway, and Sweden) using national health registry data.
   Findings: Children born after frozen embryo transfer had a 60% to 70% higher relative risk of developing childhood cancer compared to naturally conceived children.
   Specific Cancers: The elevated risk was driven primarily by higher rates of pediatric leukemia and central nervous system (brain) tumors.
   
2. The Taiwan National Health Cohort Study (JAMA Network Open, 2022)
   Scope: Evaluated 2.3 million parent-child triads using Taiwan’s National Health Insurance Research Database between 2004 and 2017.
   Findings: Children conceived via ART demonstrated a 58% higher relative risk of childhood cancer compared to naturally conceived peers.
   Specific Cancers: The statistical increase was concentrated mostly in cases of leukemia and hepatic (liver) tumors.
   
3. French National Health Data System Cohort (SNAI, 2021)
   Scope: Followed over 8.5 million children born in France.
   Findings: Observed a modest, statistically significant elevation in overall pediatric cancer risk among children conceived through assisted reproduction.
   
4. Global Meta-Analyses and Pooled Reviews
   Scope: Comprehensive systematic reviews pooling observational data across tens of millions of children in North America, Europe, and East Asia.
   Findings: Pooled data consistently show a overall relative risk elevation for ART-conceived children between 15% and 35% (a hazard ratio of roughly 1.15 to 1.35) compared to natural conceptions, with frozen embryo transfers consistently anchoring the higher end of that statistical range.

Why aren’t we being told about this?
