Dr. Francesca Duncan's pioneering work at the Buck Institute reveals why reproductive aging matters for business and society
In the fast-evolving landscape of longevity science, one researcher has made a discovery that could fundamentally alter how we think about women's health, productivity, and the economics of aging. Dr. Francesca Duncan, Thomas J. Watkins Memorial Professor of Reproductive Science at Northwestern University and Associate Professor in Residence at the Buck Institute for Research on Aging, has identified a mechanism of reproductive aging that could lead to multibillion-dollar advancements in women's health.
"The female reproductive system is one of the first to show overt signs of aging in the human body," explains Dr. Duncan. While most organ systems begin deteriorating in our 60s or 70s, women's ovaries start declining in their mid-30s, with reproductive function ceasing entirely at menopause, typically around age 50.
This timing creates a critical disconnect in modern society. "Due to medical and health advances, women are living longer than ever before," Dr. Duncan notes. 'For women, however, this is especially problematic because the time of menopause has stayed constant. Thus, women are living longer post-menopause in an altered endocrine milieu.'
The breakthrough began with a simple observation in the laboratory. When isolating eggs from ovaries, Dr. Duncan's team noticed that tissues from older animals were physically tougher to work with. This "happy accident" led to a critical realization: aging ovaries develop inflammation and fibrosis—essentially internal scarring—that makes the tissue physically stiffer.
"By serendipity we discovered the importance of the microenvironment in which the egg develops and how that may be contributing to ovarian aging," says Dr. Duncan. "The aging ovary assumes a proinflammatory and fibrotic phenotype that leads to a stiffer microenvironment."
This finding has significant implications for ovarian function. The research demonstrates that a fibrotic, stiff ovary can negatively impact follicle development, egg quality, and ovulation—all crucial factors for both fertility and hormone production.
For business leaders and investors, this research presents compelling opportunities. The implications extend far beyond family planning into workforce productivity, healthcare costs, and market development:
1. Workforce Retention and Development: As women increasingly occupy senior leadership positions, the menopausal transition often coincides with critical career advancement years. Extending ovarian function could help businesses retain experienced female talent during their most productive years.
2. Healthcare Economics: Women live longer than men on average, but as Dr. Duncan points out, "There is a longevity paradox because women spend more time in frailty and poor health relative to men." Maintaining ovarian function could reduce healthcare costs associated with conditions linked to estrogen decline, including cardiovascular disease, osteoporosis, and cognitive impairment.
3. Diagnostic Technologies: Dr. Duncan's team is developing ultrasound-based Shear Wave Elastography to measure ovarian stiffness non-invasively. "Currently this is done by transvaginal ultrasound which is a minimally invasive method, but we hope as the technology of wearable ultrasound patches advances, we will move towards a wearable for continuous and real-time ovarian health tracking," she explains. This represents a potentially significant new market in women's health diagnostics.
The potential market for therapeutics targeting ovarian fibrosis is substantial. In pre-clinical studies, Dr. Duncan's team has demonstrated that low-dose anti-fibrotic drugs can extend ovarian function and reproductive longevity.
"Through pre-clinical pipelines, we have demonstrated the therapeutic value of using pharmacologic interventions with low-dose anti-fibrotics to extend ovarian function and reproductive longevity," Dr. Duncan explains. 'This work lays the foundation for identifying additional anti-fibrotic drug targets and performing clinical trials in women.'
Unlike hormone replacement therapy (HRT), which Dr. Duncan notes "does not encompass all ovarian hormones nor does it recapitulate the complex and dynamic physiology of normal ovarian cycles," these therapeutics aim to maintain comprehensive ovarian function, addressing both fertility and endocrine health.
The business implications of this research extend globally. "First, global fertility rates are at an all-time low," Dr. Duncan points out. 'This is compounded by the fact that women are delaying childbearing and being confronted with the tangible consequences of reproductive aging.'
This demographic shift creates markets not only in the United States but worldwide, as countries from Japan to Italy grapple with declining birth rates and aging populations.
Dr. Duncan's work aligns perfectly with the Buck Institute's mission to extend healthspan—the period of life spent in good health. As Eric Verdin, CEO of the Buck Institute, has emphasized, community connection and sense of purpose are among the top drivers of healthspan.

"Improving healthspan for women through sustained ovarian function will allow them to take full advantage of community and social connections which will feed forward and further promote healthy aging and longevity," says Dr. Duncan.
For investors and business strategists, the timeline for these innovations is promising. "It is exhilarating to be able to translate our findings from bench-to-bedside in less than a decade," says Dr. Duncan. With clinical applications potentially available within a decade, this represents one of the most promising near-term opportunities in longevity science.
Dr. Duncan's research exemplifies how fundamental science can address pressing societal challenges while creating substantial business opportunities. By tackling one of the first and most consequential aging processes—ovarian aging—her work could help realign women's biological clocks with their chronological lifespans, benefiting half the world's population and transforming multiple industries in the process.
"As a society, we have accepted the challenge of living longer," Dr. Duncan concludes. "These clocks need to be reset and realigned to ensure healthy aging in women—half the world's population who are essential for the continuity of our species."

Louisiana's 2025 legislative session ends with governor saying he plans to call a special session
BATON ROUGE, La. (AP) — With just minutes to spare, Louisiana lawmakers concluded the 2025 legislative session on Thursday — but, per usual, it ended with a bang. Before lawmakers could even walk out the Capitol doors, Gov. Jeff Landry said he planned to call a special session in the future, with the hopes of reviving controversial legislation that died Thursday. It is unclear when exactly lawmakers would be asked to return. Last-minute amendments to bill, which would prohibit companies from owning both pharmacy benefits managers and drugstores, caused a frenzy in the final days of session — complete with fiery testimony from lawmakers, a massive lobbying campaign to block the measure by retail giant CVS and promises of legal action by the Attorney General. Also in the final hours of session lawmakers approved the state's $51 billion budget. Lawmakers earmarked $1.8 million for 'expenses related to the recapture of fugitive offenders' in the aftermath of a massive New Orleans jail escape. They also pulled $1.2 billion from a state savings fund mainly to spend on infrastructure improvements and spruce up sites seeking private sector investment. In a blow to Landry, the GOP-dominated Legislature allocated less than half the $93.5 million he requested for expanding a school voucher program. Traditionally this year's gathering is fiscally focused, But the GOP-dominated legislature filed hundreds of bills to tackle issues that lawmakers felt were plaguing the state, from fiscal matters to social issues. Here's a look at some of the bills. Passed ABORTION LIABILITY EXPANSION: The measure expands who can be sued over abortions, targeting out-of-state doctors and activists who prescribe, sell or mail pregnancy-ending drugs to residents in Louisiana — where abortions are banned with few exceptions. MAKE AMERICA HEALTHY AGAIN: Louisiana passed its own package of nutrition reforms. The measures restrict certain food additives in schools, set nutrition education requirements for health care providers, require food manufacturers to disclose the use of certain artificial ingredients, and order restaurants to post if they are using seed oils. INSURANCE: Despite facing stiff opposition from the insurance industry and pushback from Republican lawmakers, Landry succeeded in passing legislation giving the state's insurance commissioner more authority to block auto insurance rate increases by companies. Other passed bills aim to limit the damages for people involved in vehicle accidents, such as barring damages to cover injuries for the driver primarily responsible for a crash. IMMIGRATION: Lawmakers passed a package of legislation that expands the state's role in immigration enforcement and promises cooperation with federal efforts. One bill would make it a crime for law enforcement agents and public officials to obstruct federal immigration enforcement efforts. Another measure requires state agencies to verify and report anyone illegally in the U.S. who is receiving state services. ETHICS: Lawmakers overwhelmingly approved a bill written by the governor's personal attorney that makes it harder for the state's ethics board to investigative allegations of wrongdoing and file charges against elected officials. IVF TREATMENT: In an effort to avoid what happened in Alabama, lawmakers passed a bill that protects in vitro fertilization providers from criminal charges and lawsuits. CAMPAIGN FUNDING: Lawmakers raised the disclosure thresholds for campaign finance matters, meaning less information will be shared with the public about the donations they receive and their spending of donations. They also expanded the ways elected officials' campaign funds could be spent, including on Mardi Gras celebrations in Washington, D.C. IVERMECTIN: One measure allows the antiparasitic drug, a discredited COVID-era treatment, to be sold for over-the-counter use. WEATHER MODIFICATION: Louisiana is the latest state to prohibit anyone from 'intentionally' injecting, releasing, applying or dispersing chemicals into the atmosphere with the purpose of affecting the 'temperature, weather, climate, or intensity of sunlight.' Rejected DIVERSITY, EQUITY AND INCLUSION: After emotional pleas from Black lawmakers, a bill that bans state government DEI programs died on the vine in the Senate. SPLIT JURY: Incarcerated people, who were convicted under the now-banned practice of split juries, would have had the opportunity to ask for a new trial under one proposed measure. However, Republicans rejected the bill. MINIMUM WAGE: One bill would have gradually increased Louisiana's minimum wage, which currently stands at $7.25, over the next four years. Similar bills have repeatedly been shot down. ABORTION BAN EXCEPTIONS: For the third year, lawmakers rejected a bill that would have added rape, in cases where the victim is under the age of 17, to the narrow list of exceptions to the state's abortion ban. LGBTQ WORKPLACE PROTECTIONS: A measure that would prohibit employment discrimination based on gender identity and sexual orientation failed in committee. FLUORIDE BILL: A bill that would have outlawed fluoride in Louisiana's public water systems failed.

Health is not a matter of instant gratification
In a time where almost anything you could want is just a tap away—AI-powered answers in seconds, groceries delivered within the hour, endless content streamed instantly, and real-time validation through likes and shares—it's no surprise that we've come to expect that same level of immediacy from our health. GLP-1 drugs promise rapid weight loss. Telemedicine provides patient care from the comfort of your own couch. At-home diagnostic tests deliver near-instant health insights. Social media and on-demand culture have rewired our brains to crave this kind of instant gratification, trapping many of us in a dopamine loop—that endless cycle of seeking out short-term rewards at the expense of long-term well-being. The consequences of this mindset are much deeper than we realize. In fact, the ripple effect is reshaping how we view our bodies, our health, and what it means to feel good. And it's taking a toll on our physical and mental health. The health and wellness industry, which should be offering a counterpoint to this culture, has too often played into it, promising overnight results, quick fixes, and immediate transformations. The truth is, our bodies don't operate on the same timeline as our screens. The disconnect between instant gratification and whole-body health Biological transformation is a slow and intuitive process, one that unfolds over months and years, not overnight. Yet we've been conditioned to feel like we're failing if we don't see instant results. This gap has real consequences: People abandon solutions that could meaningfully improve their health simply because they haven't delivered fast enough. In the chasing of short-term wins, we're ignoring the foundational systems that fuel long-term well-being: our stress response, hormone health, gut microbiome, and the delicate balance of nutrients that power our bodies. The rise of quick-fix wellness has only reinforced this cycle. The common thread? They all offer a dopamine hit—a fleeting sense of progress—without addressing the root causes of why we don't feel good in the first place. The problem is, quick wins rarely translate to lasting health. When we expect instant results from our bodies, we're setting ourselves up for disappointment, and that disappointment breeds distrust. We start to believe that our bodies are failing us, when in reality, it's our expectations that need recalibrating. What's more concerning is that this mindset is compounding the very issues we're trying to solve. Stress, fatigue, thinning hair, breakouts, brain fog—these are all signals that our bodies are out of balance, not problems to be hacked. But in the dopamine loop, we treat the symptoms, not the root causes. So the cycle continues. A new mindset: Longevity over quick fixes The most profound health transformations happen when we work with our bodies, not against them. This requires a radical mindset shift—one that prioritizes optimization over instant gratification and rewires the way we measure progress. What if the question wasn't 'How quickly will this work?' but instead 'How will this support the future version of me?' This is the mindset of whole-body longevity—the belief that how we feel today is deeply connected to how we'll feel five, 10, or 20 years from now. It's about setting your body up to not just feel good right now, but to stay strong and thrive for the long haul. As an industry, we have a responsibility to lead this shift. That means telling the truth about what it really takes to transform your health—that lasting change happens over months, not days. It means designing products that address the root causes of how people feel, not just surface-level symptoms. And it means empowering people to celebrate progress, not perfection, and to understand that feeling better is a journey, not a destination. The future of health is whole-body True wellbeing doesn't come from quick fixes; it comes from lasting habits. While treatments and medications can offer short-term relief, sustainable transformation requires a deeper, long-term commitment to how we live every day. Whole foods, regular movement, quality sleep, stress management, and mindful choices like reducing alcohol—these aren't trends; they're the foundation for clarity, resilience, and longevity. When these habits are supported by science-backed clinical tools, they create the conditions for real, lasting change. Health becomes something we cultivate, not hack. Imagine if we shifted the focus from fast results to long-term vitality. If success was defined not by how quickly we feel better, but by how well we're preparing our bodies and minds to thrive for decades to come. This is the future of health: slow, intentional, science-driven, and whole-body, because no part of us functions in isolation. As leaders, aligning with this vision means building not just better businesses, but a healthier world.
