Study reveals potential causes of infertility

Published

on

A 556-gene signature in the uterine lining may help explain why some embryo transfers fail, even when clinics use chromosomally normal embryos, new research suggests.

Even in the best-case scenario, when clinics transfer embryos with a normal number of chromosomes into a woman’s uterus, only about half result in a live birth.

Some transfers lead to pregnancy followed by miscarriage, but in 30 to 35 per cent of cases the embryo does not implant in the uterus at all.

For decades, fertility research has focused heavily on embryo quality, but some scientists suspect the problem can lie in the uterus itself. New findings support that view.

Researchers at Rutgers Health and Michigan State University identified genes concentrated in gland cells in the uterine lining, known as the endometrium, that rise in fertile women during the brief window when the womb can accept an embryo.

The team enrolled 30 patients with regular menstrual cycles and proven fertility.

Participants used ovulation predictor kits and worked with researchers so tissue samples were taken at precise points in the cycle.

Blood hormone levels and microscopic checks were used to confirm timing, adding rigour the researchers said was missing from earlier work.

To track the endometrium’s changing biology, the team used two sequencing approaches: one measuring gene activity across the whole tissue and another measuring it cell by cell. Both pointed to the same pattern.

The biggest molecular shift came as the cycle entered the mid-secretory phase, the stage typically linked with implantation.

The sharpest changes were seen in specialised uterine gland cells that produce molecules thought to nourish an embryo and help coordinate implantation.

Earlier studies had shown these glands matter in mice and sheep, but the authors said this is the first human evidence pointing to a central role for this glandular tissue.

They also noted that their results in mostly Black and Hispanic patients matched findings from mostly white patients in past research, suggesting similar factors may drive infertility across races.

From these patterns, the researchers defined a 556-gene signature they called the Glandular Epithelium Receptivity Module.

When they applied a score based on this signature to published datasets, it was consistently lower in women with recurrent implantation failure or pregnancy loss than in fertile controls.

The work is not yet ready for clinical use.

Nataki Douglas, an associate professor of obstetrics, gynaecology and reproductive health at Rutgers New Jersey Medical School and senior author of the study, said the next steps include shortening the gene list and recruiting patients with implantation failure to test whether the signature predicts outcomes.

“This was one of the first attempts to really look at the menstrual cycle in women who are fertile and try and understand how the endometrium is changing, how it becomes briefly receptive to embryo attachment at the most fundamental level,” Douglas said.

“Once we can identify those who are at risk and the genes that are the most important in this 556, ones that we know code for particular proteins we might be able to add synthetically, then we may be able to work on therapeutic approaches.”

From Hologic to Ark Surgical: Why Joseph LaBruzzo is betting on the future of women’s surgical innovation

Published

on

After more than two decades leading organisations at some of the world’s most respected medical device companies, including Hologic, SenoRx Breast Care, and BTL Industries, Joseph B. LaBruzzo is embarking on a new chapter as President & CEO of U.S. Operations and Board Member at Ark Surgical.

We sat down with Joseph to discuss what drew him to Ark Surgical, why he believes women’s surgical innovation is entering a transformative era, and what it takes to bring meaningful technologies from concept to standard of care.

You have held leadership positions at some of the biggest names in MedTech. What attracted you to Ark Surgical?

Throughout my career, I’ve been fortunate to work with organisations that developed technologies capable of changing the standard of care.

What attracted me to Ark Surgical is the opportunity to help address a meaningful unmet need in gynecologic surgery with an innovation that has the potential to improve patient outcomes while preserving the benefits of minimally invasive surgery.

Opportunities like that don’t come along very often.

FemTech World recently highlighted that many women remain unaware of gynecologic cancers and that unexpected diagnoses continue to have a profound impact on patients and families.

How has your own experience shaped the way you think about innovation in women’s health?

Earlier in my career, I witnessed many women receive life-changing cancer diagnoses.

Those experiences stayed with me and reinforced my belief that if there’s an opportunity to reduce risk through better innovation, it’s one worth pursuing.

That’s one of the reasons I was drawn to Ark Surgical.

The vast majority of minimally invasive gynecologic procedures are performed for conditions believed to be benign. Unfortunately, in rare cases, pathology later reveals an unexpected malignancy.

LapBox was designed with a proprietary dual-wall tissue containment system to help facilitate contained specimen retrieval and minimise the risk of tissue spillage during laparoscopic procedures.

I believe innovations like this can help surgeons manage the unexpected while preserving the many benefits of minimally invasive surgery for women.

Women’s health has gained significant momentum in recent years, yet surgical innovation often receives less attention than diagnostics or therapeutics. Why do you think that is?

Women’s health has historically been underfunded and underserved across many areas of medicine, and surgery is no exception.

While we’ve seen tremendous advances in diagnostics and pharmaceuticals, there are still important opportunities to improve the surgical experience for both physicians and patients.

Innovation that enhances safety, efficiency, and outcomes has the potential to make a lasting impact.

What excites you most about LapBox?

LapBox addresses a very real challenge that gynecologic surgeons face during minimally invasive procedures.

It was thoughtfully designed to integrate seamlessly into the surgical workflow while providing an added layer of confidence when tissue retrieval is required.

I believe technologies that solve real clinical challenges in a practical way have the greatest potential to become part of the standard of care.

What do you see as the biggest unmet needs in minimally invasive gynecologic surgery today?

The future of surgery isn’t simply about making procedures less invasive. It’s about making them smarter and safer.

Surgeons need technologies that integrate seamlessly into their workflow while helping them navigate increasingly complex clinical situations.

Every advancement that helps reduce risk while preserving the benefits of minimally invasive surgery has the potential to improve outcomes for both physicians and patients.

That’s where I believe the greatest opportunities for innovation exist.

As you take on this new role, what are your priorities over the next 12 months?

Our focus over the next 12 months is to build a strong foundation for growth. That means expanding physician partnerships, driving early clinical adoption, growing our team, and ensuring that more surgeons have access to technologies like LapBox.

At the same time, we’re focused on building strategic relationships with investors, healthcare systems, and industry partners that support our long-term vision.

What advice would you give entrepreneurs building the next generation of women’s health companies?

Start with a real clinical problem and never lose sight of the patient.

Great technology alone isn’t enough. You also need strong clinical evidence, physician advocates, and a clear market strategy. The companies that succeed are the ones that bring all of those pieces together while remaining focused on improving patient care.

About Joseph B. LaBruzzo

Cancer cells secretly hijacking fertility protein to survive chemo, research finds

Published

on

Cancer cells may hijack a fertility protein to repair damaged DNA and survive chemotherapy, research suggests.

The findings could point to a way of making existing cancer treatments more effective.

SYCP1 is a protein normally involved in producing sperm and eggs.

Researchers at the University of Liverpool found that the protein, previously thought to work only in reproduction, can be reactivated in cancer cells, where it helps tumours survive and grow.

SYCP1 usually helps chromosomes pair during meiosis, the form of cell division that produces reproductive cells.

In cancer cells, however, the protein appears to take on another role. It enters the nucleus, the cell’s control centre, binds directly to DNA and regulates genes involved in cell division and DNA repair.

DNA repair is how cells fix damage to their genetic code. In cancer, this process can help tumour cells survive treatment.

The researchers found that removing SYCP1 made cancer cells much more sensitive to chemotherapy drugs that damage DNA.

The findings suggest cancers may use SYCP1 to repair damage caused by treatment and continue growing.

Dr Urszula McClurg, lecturer in biochemistry, cell and systems biology at the University of Liverpool, said: “Our findings show that cancer cells can hijack proteins that normally exist only in reproductive tissues and give them completely new jobs.

“Understanding these unexpected functions opens up exciting opportunities to develop new treatments that make existing cancer therapies more effective.”

The work challenges the long-held belief that proteins active only in fertility have no biological relevance outside the reproductive system.

Researchers say these specialised proteins could provide new treatment targets across many types of cancer.

The study also offers a new view of how cancers evolve by repurposing developmental and reproductive processes.

The findings highlight SYCP1 as a candidate for future precision cancer therapies, which are treatments based on the specific biology of a patient’s cancer.

What “women’s healthmaxxing” means for patient trust and the femtech industry

Published

on

Women’s health has become one of the most searched and shared topics online, from cycle syncing and cortisol management to menopause hacks, supplements, hormone testing and clinician-creator content.

That surge in attention, sometimes dubbed “healthmaxxing,” is changing how women find, evaluate and act on health information, and it is starting to reshape the relationship between patients, clinicians and the companies building products for this market.

For providers, the shift means patients are arriving better informed but also more exposed to unverified claims, putting pressure on clinicians to engage with online narratives rather than dismiss them.

For femtech and pharma companies, it opens a route to reach and educate consumers at scale, but also raises the stakes on credibility: products and messaging that ride the trend without clinical grounding risk eroding the trust the industry has spent years building.

Investors are watching the same dynamic from a different angle.

Attention-driven demand can be a signal of where the next wave of femtech growth will come from, but distinguishing genuine clinical need from viral momentum is increasingly part of due diligence.

The net effect is a widening gap between companies that treat cultural attention as a distribution channel for credible, evidence-based care, and those that risk being swept up in trends with little clinical substance behind them.

How that gap plays out will shape patient trust, clinical relationships and commercial opportunity across the women’s health industry for years to come.

These themes will be explored in more depth in an upcoming webinar, “Women’s Healthmaxxing: The Opportunity & Risks of Cultural Attention for the Women’s Health Industry,” hosted by the Women’s Health Innovation Summit (WHIS), featuring Ellen Wilcox (Listen Ventures), Jessica Bell van der Wal (Frame Fertility), Dr. Tosin Sotubo-Ajayi (NHS, BBC and more) and Nora Lansen (Elektra Health).
