‘Devastating’ fault at London clinic may have damaged eggs of more than 100 women
Patients have only recently been told their eggs and embryos may not survive the thawing process if they were frozen with the faulty solution

More than 100 women who had their eggs frozen at a leading NHS clinic have been told that they may have been damaged due to a fault in the freezing process.
The assisted conception unit at Guy’s hospital in London said it may have inadvertently used some bottles of a faulty freezing solution in September and October 2022. However, it said it did not know the liquid was defective at the time.
Many of the 136 women affected have subsequently had cancer treatment since having their eggs or embryos frozen, which may have left them infertile, The Times reported.
The patients have only recently been told their eggs and embryos may not survive the thawing process if they were frozen with the faulty solution.
The fertility regulator, the Human Fertilisation and Embryology Authority (HFEA), is investigating.
It said a safety notice about the faulty freezing solution was issued by the authority to all clinics in February last year. However, this was several months after bottles from a faulty batch were used at Guy’s hospital’s assisted conception unit.
HFEA described the investigation at Guy’s hospital as “ongoing”, adding that it would take “any further action required”.
The regulator said that faulty egg-freezing products had also affected Jessop Fertility in Sheffield, but it said it was satisfied that Jessop “undertook a thorough investigation when they first became aware of the issue and contacted and supported any patient affected”.
“The HFEA can confirm that this issue is limited to two clinics in the UK: Guy’s and St Thomas’ Assisted Conception Unit, London and Jessop Fertility, Sheffield,” said Rachel Cutting, director of compliance and information at the HFEA, in a statement.
“Our ongoing investigation only relates to Guy’s as we are satisfied that Jessop’s undertook a thorough investigation when they first became aware of the issue and contacted and supported any patient affected.
“The company supplying the product directly to clinics will know exactly where it’s gone through their traceability processes. The company is also obliged to report any problems to the MHRA.”
“Any patients likely to have been affected will have been notified by their clinic. We hope this provides reassurance to anyone concerned.
“Fertility treatment in the UK is generally very safe. Our most recent report shows that out of the almost 100,000 treatment and storage cycles which took place in 2022/23, more than 99 per cent were conducted without any incidents occurring.”
Dr Piraye Yurttas Beim, researcher in molecular biology and embryology and founder of Celmatix, told Femtech World: “This is a reminder that the safest place for a woman’s eggs is in her own ovaries and not a freezer.
“Women lose their ovaries far too frequently due to a lack of diagnostics that would allow earlier detection of ovarian cancer and also due to ovarian damage from chemotherapy.
“Creating a new standard of care that protects ovarian function for women undergoing cancer treatment is a big focus for us at Celmatix. These stories are both heartbreaking and also a reminder of why we come to work everyday.”
Dr Cristina Hickman, a consultant clinical embryologist, lecturer at Imperial College London and co-founder of Ovom Care, said: “As an embryologist, I was devastated to learn of the unfortunate incident that has come to light at Guy’s hospital.
“Despite our best efforts to uphold the highest standards of care, incidents do occur, even if rarely. These errors, while rare, profoundly impact patients and the dedicated embryologists who strive to fulfil the shared goal of helping families conceive.
“It’s devastating news for those affected and they have our full support and we should wait to learn more from the professional team investigating this incident.
“But we must also recognise the tireless efforts of embryologists, who bear the weight of this responsibility and work diligently to maintain a low error rate.
“As fertility professionals, it’s our duty to utilise the most advanced tools available to minimise any risks that could affect our patients’ chances of having a baby. By embracing innovation and continually improving our practices, we can ensure that incidents like these become even rarer in the future.”
Sarah Norcross, director of the Progress Educational Trust (PET), commented: “It will be distressing for women with frozen eggs to learn that, due to problems outside their control, their eggs may not survive the thawing process.
“When a woman freezes her eggs, time is of the essence. In all cases, the quality of eggs declines upon reaching a certain age. Additionally, in cases where women are freezing eggs for medical reasons – for example, imminent cancer treatment – they will not want their treatment to be delayed.
“If women affected by this incident have undergone medical treatment which has compromised their fertility, then their opportunity to have a biologically related child may have been lost.
“If women affected by this incident had sought to extend their reproductive choices by freezing their eggs, then they too may have lost their best opportunity to have a family, if the quality of their eggs has declined during the period that has elapsed.”
She added: “We still do not know all the details of why this incident occurred. Hopefully, further details will be forthcoming. What does seem clear is that there was an appalling delay of around a year between this problem being known about, and affected patients being notified. Apparently, there are also some patients with frozen embryos who are similarly affected.
“We need to understand more about what precisely has gone wrong, and what the relevant regulators – including the HFEA and the MHRA – are doing about it. We also need reassurance, from regulators and clinics alike, that processes are in place to notify patients in a timely way when things go wrong.”
Becky Kearns, chief executive at Fertility Network UK, told Femtech World: “We are heartbroken to hear of the news that patients have potentially lost precious eggs and embryos.
“We want to reassure patients that incidents like this are extremely rare in the UK. We know that for many people, particularly those whose fertility has been impacted by cancer treatment, egg freezing can be a lifeline and can often be the difference between being able to have the family they have longed for.”
“As the national fertility charity, we urge anyone who may have been affected by this news, directly or indirectly, to please reach out to us for support. You are not alone.”

Clue spotlights seven women’s health journeys in new campaign

“She Had No Clue, Until She Did.” draws on real member experiences, from PMDD and painful periods to fertility and mental health.
Cycle-tracking app Clue has launched a new campaign, “She Had No Clue, Until She Did.”, built around the experiences of seven of its members who found clarity about their health after years of symptoms, questions and hormonal uncertainty.
The campaign captures the moment each woman finally connected the dots, whether that was a PCOS diagnosis that made sense at last, the realisation that anxiety followed a pattern, or a conception journey that suddenly felt less overwhelming. The stories span PMDD, painful periods, fertility, mental health and cycle-related wellbeing.
According to Clue, that moment of clarity often arrives later than it should, with symptoms dismissed, concerns minimised and hormonal health poorly understood. Too many women, the brand says, leave appointments with unmet needs, made to believe their pain was in their heads when they were simply missing the proof.
For some members, tracking their data led to a diagnosis. For others, spotting patterns brought reassurance, confidence, or the language to explain something they had lived with for decades. Clue frames the campaign as part of a broader shift in women’s health, with more women paying attention to patterns, asking questions and seeking to understand their own hormonal picture.
“The most meaningful stories are often the ones that people recognise in themselves,” said Louise Troen, chief marketing officer at Clue. “What struck us throughout this campaign was not how different these women’s experiences were, but how familiar they felt. The uncertainty, the self-doubt, the sense that something wasn’t quite right, and then the moment when everything finally clicked into place.
“The more time we spent listening, the more obvious it became that some of the most powerful stories were already within our community. Personal stories, but not isolated ones. Experiences that felt unique to the women sharing them, yet instantly recognisable to so many others. This is what we believe makes Clue so unique as a brand, and by championing some of our real, raw and relatable stories, we hope even more women can feel less alone.”
Meet the members

Faye, 36 PMDD, ADHD and hormones Faye began tracking her cycle two years ago and received a PMDD diagnosis three months ago. By the time her doctor asked her to track her symptoms, she already had the information ready. Tracking supported her diagnosis and also revealed a connection between her ADHD symptoms and different phases of her cycle, helping her understand patterns she had previously put down to stress and overwhelm.

Deirdre, 35 PMDD and emotional wellbeing For years, Deirdre noticed recurring anxiety, brain fog and emotional overwhelm in the lead-up to her period, but struggled to understand why. After her doctor suggested PMDD, tracking helped reveal a clear pattern. Understanding the role her hormones were playing transformed how she approached her mental wellbeing, helping her plan ahead, show herself more compassion and navigate difficult stretches.

Calypso, 32 Adenomyosis, fertility and diagnosis Living with painful, heavy periods for much of her adult life, Calypso used tracking to document symptoms that were often dismissed. Over time, that evidence helped support diagnoses for adenomyosis and an autoimmune condition, with investigations for endometriosis ongoing. More recently, tracking also played a part in helping her and her wife navigate fertility treatment and pregnancy planning.

Brianna, 32 PCOS and self-advocacy After experiencing irregular periods from a young age, Brianna struggled to find information that reflected their reality. Tracking helped build a clearer picture of their health, ultimately supporting a PCOS diagnosis and providing evidence to bring into healthcare conversations. They continue to track as a way of monitoring changes and advocating for themselves when something doesn’t feel right.

Giulia, 35 Fertility and conception After 15 years on hormonal contraception, Giulia began tracking her cycle as she prepared to start trying for a baby. What began as a practical tool quickly became a deeper education in her own reproductive health. The insights she gained aligned closely with guidance from her gynaecologist, helping her approach conception with confidence and supporting her journey to pregnancy.

Eva, 32 Self-confidence and body literacy For Eva, tracking was the start of a broader journey towards understanding and trusting her body. After years of feeling dismissed by healthcare professionals and offered one-size-fits-all solutions, she began paying closer attention to her own patterns. The result was a stronger sense of agency, confidence and connection to her health.

Paula, 29 Fitness, PMS and performance A Clue member for more than a decade, Paula sees her cycle as a valuable source of information rather than a monthly inconvenience. Tracking has helped her understand changes in energy, recovery, PMS and performance, while also giving her evidence to advocate for herself when symptoms became more severe. What began as period tracking evolved into a deeper understanding of her overall wellbeing.
Rollout
“She Had No Clue, Until She Did.” rolls out across Clue’s channels from late June through a series of films, interviews and storytelling content exploring the moments women finally connected the dots. Member interviews and imagery are available on request, alongside expert insight from Clue chief executive Rhiannon White, chief marketing officer Louise Troen, and chief medical officer and OB/GYN Dr Charis Chambers.

The danger of ‘efficiency culture’ in women’s mental tech

By Somayeh McKian, a member of the clinical advisory board of Vea, the AI-powered mental health journal app
The danger of efficiency culture in women’s mental tech is that we are inadvertently optimizing the very patterns that drive our collective burnout.
When we look at the explosive growth of the femtech sector, the dominant narrative remains focused on speed, tracking, and passive compliance.
We build apps that treat a woman’s emotional state like a broken supply chain or a medical deficit that needs to be optimised, streamlined, or forced into submission.
But true psychological resilience cannot be quantified by a simple mood slider or an algorithmic checkmark.
As a psychotherapist and gender studies scholar, my research into the lived experiences of women, particularly how cultural mandates and bodily surveillance are pathologised, reveals a deep-seated form of suffering.
When women constantly say “yes” while meaning “no,” or ignore a chronically depleted body to maintain a rigid role, they are living out what I call an “inkless life.”
It is a blank manuscript in which their physical and emotional existence has been entirely authored by external critics, medical charts, and the “Discourse of the Other.”
They aren’t suffering from an efficiency problem; they have been stripped of the agency to author their own skin.
If femtech platforms simply digitise these rigid, externalised “shoulds,” they risk becoming high-tech tools of compliance rather than portals of liberation.
The investment community and health tech innovators need to realise that the next frontier of mental health tech isn’t about managing symptoms on the fly; it is about existential archaeology.
We must build digital spaces that serve as a “corporeal pen,” transforming self-reflection from a passive hobby into a defiant, existential act.
True innovation lies in helping women find the meaning, the latent metaphors, and the unique tasks already written into their struggles and transforming inherited pain into a human achievement.
This is exactly the structural paradigm shift we are anchoring at Véa. Instead of building superficial tracking logs, our architecture treats life as a manuscript.
We design clinical narrative journeys that help women decode where their internal boundary scripts were written, recognize how somatic depletion is a truth-teller, and wield phrases like “stop it” not as external policing, but as internal, defiant boundaries.
If we want to build a sustainable ecosystem for women’s health, we must stop funding platforms that merely help women endure their exhaustion more efficiently.
In the intersection of meaningful life and technology, we look at the human spirit not by its current restrictions but by its latent potential for change.
It is time to back technologies that give the fluent soul a sharp new set of instruments to rewrite its own narrative.
