Bouncing off my last umbilical cord post… here are the studies.
Because I know some of you are asking for proof.
Well… here it is.
You don’t need to be a medical doctor to see the science.
Just willing to read what’s been buried under hospital policy and “standard practice.”
They told you the umbilical cord and placenta were medical waste.
They told you early cord clamping was “best practice.”
They told you stem cells were something you needed to bank for thousands of dollars…
Instead of just letting your baby receive what was already theirs.
But here’s the truth:
👉 That umbilical cord holds up to 30% of your baby’s total blood volume
(https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9056455/)
👉 It’s packed with oxygen, iron-rich red blood, stem cells, and immune cells designed to seed your baby’s entire system.
👉 And clamping it early cuts them off from all of it.
We’re talking about the difference between:
- anemia or strength
- inflammation or immune balance
- struggling organs or a supported transition into life
Most placental transfusion happens within the first 3-5 minutes after birth, especially if you wait until the cord stops pulsing or turns white. That’s the sign it’s done its job.

And yes—this is backed by science:
A randomized trial showed 60 seconds of delayed clamping significantly increased CD34⁺ stem cells and reduced anemia

A Scientific Reports study found that waiting 60 seconds yielded higher hemoglobin, more stem cells, and better hematocrit levels

A Cleveland Clinic trial showed 120 seconds of delay improved cardiac output and oxygenation

The WHO and ACOG recommend 30-60+ seconds of delay as standard

A Swedish study found that children who received full transfusions (3+ min delay) had better fine motor and social development at age 4

Even cord milking and extended delays past 3 minutes can offer additional stem cells, oxygen, and protection for preemies and high-risk births

So if you’ve ever heard someone scoff at the idea of waiting 10, 15, or even 20 minutes…
Just remember this:
There’s no harm in waiting… and everything to gain.
Let the cord go white. Let the transfusion finish.
You only get one chance.
And about those placentas?
They’re not waste either.
They’re sold… for research, cosmetics, pharma-grade compounds.
Just not to you.
So no… it was never “useless.” It just wasn’t profitable for you to keep it.
Background:The umbilical cord blood contains a high concentration of stem cells. There is not any published study evaluating the amount of stem cells that ha...
