Menstrual health: how ‘donating your period’ could advance women’s health
Could your menstrual blood help researchers? This entrepreneur thinks so
Imagine a world where women could use their menstrual blood to screen, diagnose and monitor a range of health conditions, all while contributing to valuable research and product development.
It’s not wishful thinking; it’s the bold idea of the South African entrepreneur and female health advocate, Karli Büchling, who is establishing Europe’s first period biobank.
A self-described problem solver, Büchling thinks Yoni Health could not only help millions of women manage their health, but completely transform the women’s health landscape by allowing people to donate their periods for medical research.
The process would be simple. Women would download an app, track their period, collect the menstrual blood and send it to the biobank, where the exciting part begins.
“Businesses and researchers working with us will be able to have access to the samples for research and product development; they could choose to either get us to do the research for them in our lab facilities or they could have their own scientists do the research,” Büchling explains.
That research though won’t be solely limited to female-specific health conditions.
“We are planning to go into a range of health conditions, such as ADHD, Parkinson’s, Alzheimer’s and cancer, and other areas that haven’t previously been explored,” says Büchling.
“We see a future where women can use their periods to self-diagnose and manage their health and where researchers and health professionals can provide safe and effective equitable healthcare solutions that work for the female physiology.”
Gender bias in healthcare
Around 1.8 billion people menstruate every month worldwide, meaning 800 million women and girls are on their period on any given day. Given those numbers, surprisingly little is known about menstrual blood itself.
“There are less than 400 studies done on menstrual blood – that’s compared to more than 16,000 on erectile dysfunction,” says Büchling. “We know very little about menstrual health and we have little to no education about periods.”
Historically, medical studies have excluded female participants and research data have been collected from males and generalised to females. The gender gap in medical research, alongside overarching misogyny, has resulted in real-life disadvantages for women.
“Misogyny and sexism have a lot to answer for when it comes to understanding the female body,” Büchling agrees.
“Healthcare today is based on the male physiology and it’s based on the assumption that the female physiology is exactly the same as the male physiology. Although we now know that that is not the case, we don’t understand very clearly what the differences are.”
She says: “We may not be treated as the default, but we need to move to a place where the male and the female physiologies can coexist.
“The more research we can do, the more data we can collect, the more analysis we can complete, the better solutions and innovations we can create that could serve the female physiology in its entirety.”
Things won’t change over night, the entrepreneur admits, but she remains optimistic.
“I made it my mission to make women’s health research more accessible not only to businesses and researchers, but to every single person who wants to contribute.
“I want to be an enabler and I want the biobank to be part of that.”
Yoni Health’s biobank is expected to launch in 2025. Join the waiting list at yoni.health.

The Full Speaker Lineup is Confirmed
The full speaker lineup has finally been confirmed, with 80+ voices spanning investment, innovation, policy, medtech and pharma.

NYSE Partnership: A Quick Recap
For those who missed our announcement on Femtech World last week, the New York Stock Exchange is the Official Exchange Partner of Women’s Health Week USA 2026.
On the morning of May 13, WHW will feature in the NYSE Market Update, reaching approximately 200 million viewers.
Women’s Health Week will also light up the North Star Billboard in Times Square for a full week around the event, with live and taped interviews distributed across NYSE Live and Taking Stock.
It remains one of the most significant institutional endorsements the women’s health sector has seen.
Early Bird Pricing Closes This Friday
Tickets increase by up to $600 after midnight on Friday, April 17. For anyone with May 13-14 in their calendar, this week is the window to move.
Flora Fertility has raised US$5m in seed funding to roll out fertility insurance across the US, with plans to expand into Canada.
The round was led by ManchesterStory, with participation from Slauson & Co., TruStage Ventures, BDC Capital, Marathon Fund, Adara Venture Capital and strategic angel investors. Existing investors include Highline Beta, Everywhere Ventures and Cartography Capital.
Laura McDonald, co-founder of Flora Fertility, said: “Fertility is one of the largest uninsured financial risks people face, yet the system today only offers support once you’re already in crisis and often only if your employer provides it.
“We’re creating a new category where fertility becomes something you can proactively plan for, not just pay for when it’s too late.”
Flora says it is introducing a new InsurTech category with individually owned, portable fertility insurance designed to address a gap in healthcare cover.
The company says it wants to shift fertility from a reactive expense to a proactive, data-driven financial planning tool, using AI, personalised underwriting and risk modelling.
The platform lets people buy coverage without relying on an employer, helping it continue through job changes and different stages of life.
Flora’s policies cover a full range of fertility treatments, including diagnostics, medications, intrauterine insemination and in vitro fertilisation, with entry-level pricing starting at about US$20 a month.
The company estimates that infertility affects one in six people globally, while treatment costs can range from US$30,000 to US$50,000, leaving the vast majority of patients without access to care.
Flora says its platform currently reaches more than 10 million prospective policyholders across North America.
The funding will be used to expand Flora’s underwriting capabilities, scale distribution and further develop its platform as it seeks to establish a new market within women’s health and insurance.
Nicole Gunderson, partner at ManchesterStory, said: “Flora is building something that has never existed before, affordable, portable fertility insurance that meets the next generation of women exactly where they are.
“The InsurTech opportunity here is enormous, and the Flora team has the expertise, technology, and vision to define this category.”
Dr Christy Lane, co-founder of Flora Fertility, added: “Fertility has always been treated as unpredictable and uninsurable, but the data tells a different story.
“The earlier someone can access that coverage, the better their outcomes and the lower their costs, which is what makes this model so powerful.
“We’re turning fertility from a reactive medical expense into a proactive, data-driven financial decision.”

When the New York Stock Exchange signs on as the Official Exchange Partner of a women’s health event, it’s worth paying attention to.
Women’s Health Week USA, taking place May 13-14 at the New York Academy of Medicine in New York City, has confirmed the NYSE as its Official Exchange Partner for 2026.
It is one of the most significant institutional endorsements the women’s health sector has seen, and it says something meaningful about where global capital markets are directing their attention.

What the Partnership Involves
This is not simply a logo on a lanyard.
The NYSE partnership comes with a set of activations that put women’s health in front of audiences well beyond the event itself.
On the morning of May 13, Women’s Health Week will be featured in the NYSE Market Update, reaching an audience of approximately 200 million viewers across outlets including Yahoo Finance and the Financial Times.
For a sector that has historically struggled for mainstream financial visibility, that kind of reach is significant.
Women’s Health Week will also light up the North Star Billboard in Times Square for a full week around the event, placing the brand at the centre of one of the most commercially visible locations in the world.
NYSE will produce live and taped interviews with WHW leadership and keynote speakers, distributed across NYSE Live, Taking Stock, and partner platforms reaching tens of millions of viewers monthly.
A dedicated NYSE content team will be on the ground at the New York Academy of Medicine capturing the conversations and connections taking place across both days.
The NYSE’s Healthcare & Life Sciences team will also take to the stage at Women’s Health Week USA, sharing their perspective on trends shaping the sector from a capital markets standpoint.
Why It Matters
The partnership is a signal as much as it is a sponsorship.
Women’s health has spent years making the case that it is a commercially serious category.
The NYSE’s involvement makes that case in a language the broader financial world understands.
Women’s Health Week USA 2026 is themed around The Era of Scale, a deliberate framing around the idea that the sector has moved beyond early validation into the harder work of institutionalisation.
Capital is moving. M&A activity is increasing. Generalist investors are entering a space that was once left to specialists. The NYSE partnership fits neatly into that narrative.
With 600+ senior decision makers confirmed across investors, founders, multinationals, payers and policymakers, the event is already one of the most commercially concentrated gatherings in the women’s health calendar.
The NYSE’s reach extends that concentration well beyond the walls of the New York Academy of Medicine.

The Pitch Sessions
For founders and early-stage companies, Women’s Health Week USA also hosts a mainstage Pitch Session across two categories: Medical Devices & Therapeutics and Consumer & Tech. Fifteen companies will be selected to pitch in front of the full audience.
Applications close April 10.
They are free to submit, and any company working on a condition that affects women exclusively, differently, or disproportionately is eligible.
