Women have superpowers in our uteruses (or is it uteri?!).
I've seen this floating around and wanted to look into it to see how much validity there is to the claim - because women know without a shadow of a doubt that there is TOO MUCH s*xism in medicine and science as we know it.
Here are the facts:
Menstrual-blood-derived stem/stromal cells (MenSCs) were first reported in 2007, with independent research identifying stem/stromal-cell populations in menstrual blood.
And they are genuinely an interesting research area. Menstrual blood provides a relatively non-invasive, repeatedly obtainable source of cells with mesenchymal-stem-cell-like properties. Researchers have investigated their potential in regenerative medicine, immune-related disease, endometrial repair, and other applications.
But, somehow, it is still in VERY early stages of research - nearly 20 years after these cells were first identified.
Curious, ain't it? Let's dig in.
A 2022 peer-reviewed analysis of research published between 2008 and 2020 found that menstrual-blood-derived mesenchymal stem/stromal cell research represented just 0.25% of the research results in their comparison of different stem-cell sources.
0.25%.
The researchers specifically concluded that the scientific output in this area remains incipient and pointed to gender bias and the social stigma surrounding menstrual blood as possible factors in why menstrual blood is so underused and its scientific value underestimated.
So no, we didn't JUST discover menstrual blood stem cells. We've known about them since 2007. But... that doesn't make this situation better. It makes it WORSE.
We've had nearly TWO DECADES to study what they can do, and we're still in the early stages of figuring out what they might be capable of.
THAT is the part that should p**s you off. Two f*cking decades.
This is not happening in a vacuum.
Women have been historically excluded from medical research to the point that the NIH created its Office of Research on Women's Health in 1990 after a federal investigation found that NIH's policies requiring women's inclusion in research were poorly communicated and inconsistently applied - and that NIH was doing very little to encourage researchers to actually analyze results by s*x.
The Women's Health Initiative was launched in 1991 as part of that course correction. More than 161,000 women were eventually enrolled across 40 clinical centers, making it one of the largest women's health studies ever conducted.
And in 2025, the Trump administration attempted to terminate funding for the Women's Health Initiative.
A landmark women's health study that had been running since the 1990s. Why? For what? Who does that help? Who does that HARM?
After massive public and scientific outcry, thankfully, the funding was restored. But we shouldn't have had to fight to continue HISTORIC research with over THIRTY YEARS of data.
Meanwhile, a 2026 analysis found that the NIH terminated 2,291 active research grants in 2025, withdrawing $2.45 BILLION in funding. Women researchers were disproportionately affected by those cancellations.
Women's bodies have been under-researched, underfunded, misunderstood, and excluded from medical research for DECADES. Our entire lives. The lives of our mothers and grandmothers.
We've spent nearly 20 fu***ng years studying the potential of cells that come out of a woman's body every month — and research in the field remains a tiny fraction of stem-cell research.
We have an entire landmark women's-health study that exists because we realized women were being left out of medical research — and then the federal government tried to pull its funding.
And we're STILL having to fight for women to be believed about their own bodies.
Sexism in medicine is real and prevalent. It isn't ancient history. It isn't some problem we solved in 1993.
It's baked into the history of medical research, and we're still dealing with the consequences.
When you underfund research into women's bodies, you don't just lose some interesting scientific discoveries.
You lose treatments, diagnostic tools, opportunities to understand diseases earlier, and opportunities to make women's healthcare safer.
And who keeps paying the price? WOMEN.
We should be DEMANDING answers about our bodies.
Instead, we're still arguing about whether the people making the decisions even need to understand them.
