Researchers expose security, privacy and safety issues in femtech
Experts are calling on policymakers to acknowledge and accommodate the risks of femtech technologies in the relevant regulations
Academics are calling for regulatory action after unveiling security, privacy and safety issues in femtech.
Researchers at Royal Holloway, University of London, Newcastle University, University of London and ETH Zurich, have identified “significant” security, privacy and safety issues surrounding women’s health technologies, such as period tracking apps and fertility smart devices.
These threats, the experts said, included the apps accessing users’ personal contacts, camera, microphone, location and other personal data, as well as system settings and other accounts that expose security and privacy risks.
Femtech apps and devices collect a wide range of data about users, their relatives, their bodies and environments.
The reserach showed that such practices can reveal sensitive and intimate information about users, such as gender, fertility, and medical data, to third parties.
The study, published in the journal Frontiers in the Internet of Things and Symposium on Usable Privacy and Security Workshop, analysed several femtech products, including a breast smart pump, cycle and fertility trackers, a smart bottle, Kegel trainers, sex toys, menopause management solutions, a digital pill organiser and general health trackers.
The research team reviewed the existing regulations related to femtech in the UK, EU and Switzerland to identify gaps in regulations, compliance practices of the industry and enforcements by running experiments on a range of femtech smart devices, apps and websites.
Their analysis of femtech-related regulations showed they are inadequate in addressing the risks associated with these technologies.
It found that EU and UK medical devices regulations do not currently have any references to femtech data and user protection.
The GDPR and Swiss FADP have references to sensitive and special category data, which overlap with femtech data, according to the research. However, the industry practices include many non-complaint practices in data collection and sharing.
The study also looked at industry non-compliance. The team identified a range of inappropriate security and privacy practices in a subset of femtech systems. The research showed that these systems do not brand as medical devices, do not present valid consent and do not give extra protection to sensitive data, and track users without consent.
The authors revealed that, not only is such intimate data collected by femtech systems, but also this data is processed and sold to third parties.
The findings have exposed a lack of research and guidelines for developing cyber-secure, privacy-preserving and safe products, they wrote.
Dr Maryam Mehrnezhad, lead author of the research and senior lecturer at Royal Holloway said: “We have identified multiple threat-actors interested in femtech data such as fertility and sex information.
“We have been conducting security and privacy research on this topic since 2019. Apart from our system studies, our user studies also highlight that end-users are indeed concerned about their intimate and sensitive data being handled by femtech products.”
She continued: “We constantly share our research results with the industry and related regulatory bodies, such as the Information Commissioner’s Office.
“We hope to see better collaborative efforts across the stakeholders to enable the citizens to use femtech solutions to improve the quality of their lives without any risk and fear.”
Professor Mike Catt of Newcastle University, one of the study authors, added: “We urge regulatory bodies to update and strengthen guidelines to ensure the development and use of secure, private and safe femtech products.
“Many of the apps surveyed access mobile and device resources too. Some of these permissions are marked as dangerous, according to Google’s protection levels. Such access potentially exposes contacts, camera, microphone, location and other personal data. Some specific permissions, such as access to system settings and other accounts on the device, also impose security and privacy risks.
“Access to sensors on the mobile phone can also be used to break user privacy. Users deserve better protection, especially where this relates to sensitive personal health and gender data.”

From AI embryo analysis in India to couples fertility care launching in the US, Korea’s women’s health startups are going global, and US investors are taking notice.
Vespexx, the femtech company behind couples preconception health platform Soonr, hosted Korea Femtech Summit 2026 on June 30 in Seoul, convening founders, clinicians, and investors from Korea, Singapore, Canada, and Japan to map the global expansion of women’s health technology.
A panel moderated by Kakao Ventures’ Jade Chung, an OB/GYN-turned-investor, captured the summit’s central theme: Korean startups taking on the world. On stage were three companies already building well beyond Korea. Vespexx, led by Co-CEO Scarlett Joowon Jung, is entering the US with Soonr; Kai Health, founded by CEO Hyejun Lee, has deployed its AI embryo-analysis software across more than 120 fertility clinics in India; and Endo Health, represented by the Head of Design Karlie Hyeonjeong Koo, has built Glow, an AI coaching app whose user base is 98% women and which is backed by US investors including a16z. Together they discussed what it takes for Korean startups to compete globally, where AI creates a real edge, and whether “K-femtech” can follow the path of K-beauty onto the world stage.
The program spanned the full arc of women’s health technology. Lindsay Davis, founder of FemTech Association Asia, opened with a look at where Asia’s femtech stands today. Dr. Juhye Lee of Ewha Womans University Mokdong Hospital offered a clinician’s view of how patient needs are shifting, arguing that women’s health is expanding beyond pregnancy and treatment toward care across the entire life course. Boram Bae, Head of Digital Health PM Part at Samsung Electronics spoke to how a consumer platform at global scale can connect women’s everyday health data with life-stage care. And Rimi Lee, head of the Femtech Center at KOSDAQ-listed diagnostics company Sugentech, traced the evolution of hormone testing from results read by eye to AI-assisted analysis, and pointed toward wearable continuous hormone monitoring as the next frontier.
Vespexx Co-CEO Scarlett Joowon Jung presented the company’s “dyadic health” approach on their ‘Soonr’ app, which brings both partners into fertility and preconception care rather than tracking a woman’s data alone, an approach validated by their legacy product, Signaling’s 800,000 users across Asia, as the company prepares for US launch.
The summit also featured Rachel Bartholomew, the Canadian founder of Hyivy Health and Femtech Across Borders, who built her pelvic-health company, and Megumi Kimura of the Japan Women’s Health Innovation Association, who outlined the investment and business models driving Japan’s fast-growing femtech market.
At the summit, Vespexx also announced the launch of Femtech Korea, an industry network intended to connect Korean femtech companies with global markets and partners, and to serve as a bridge for cross-border collaboration.
“Korea has world-class healthcare technology, but femtech has been one of its best-kept secrets,” said Scarlett Joowon Jung, Co-CEO of Vespexx. “The companies on this stage are proof that’s changing. We’re not just building for Korea anymore, we’re building for the world, and we want US partners and investors to be part of that.”
Korea Femtech Summit 2026 was hosted by Vespexx and co-hosted by FemTech Association Asia. The summit was sponsored by Sugentech, with additional support from Innerness and Octolabs.

Our sister publication Health Tech World brings its first live event to London this summer, gathering the people building, buying and regulating healthcare AI for a single afternoon. With a full line-up confirmed and two months to go, tickets are open now, and this first edition is one to book early.
Health Tech World Live, the debut live event from FemTech World’s sister title Health Tech World, makes its first appearance on Friday 21 August, bringing clinicians, founders, developers, NHS commissioners and investors together at Teesside University London in Stratford for an afternoon on where healthcare AI goes next. The programme is confirmed, and with two months to go, it is worth booking your place while the diary is still clear.
The line-up for this first edition reads like a who’s-who of UK health AI. Speakers include Dr James Harmsworth King, Chief Medical Strategy Officer at Numan, fresh from the MHRA’s AI Airlock; Dr Sonia Szamocki, founder and CEO of 01Health; Hugo Dragonetti of NHS London Procurement Partnership; Mikael Kågebäck, CTO at Sleep Cycle; Max Gattlin, Commercial Director at X-on Health; and Marcus Vass, Head of Digital Health at Osborne Clarke, with proceedings chaired by Alastair MacColl.
Across six sessions, the afternoon moves from scaling specialist care and smarter NHS procurement, through responsible delivery and consumer AI, to fair access to GP care and the regulation underpinning all of it. Between the talks, delegates get time with the speakers and the Health Tech World editorial team, the kind of access that is hard to come by anywhere else.
It is shaping up to be one of the summer’s standout dates in health tech, and a launch worth being part of from the start. If you are planning to be there, now is the time to get it booked.

Immunotherapy may temporarily restore fertility in women with autoimmune premature ovarian insufficiency, a pilot study suggests.
Three of the 10 women who received treatment later gave birth to healthy babies.
Premature ovarian insufficiency, or POI, affects just over three per cent of women worldwide and occurs when the ovaries stop functioning before the age of 40.
The condition significantly reduces fertility and can have several causes, including autoimmune processes and genetics.
Researchers at Karolinska Institutet examined whether immunotherapy could make the ovaries temporarily responsive to hormonal stimulation in women with POI caused by autoimmunity.
The study included 12 women aged between 18 and 35 with autoimmune POI.
Two withdrew before treatment began. The remaining 10 underwent ovarian hormone stimulation before receiving rituximab and again four to six months after treatment.
Rituximab is an approved and well-established medicine used to treat several autoimmune conditions and cancers.
None of the women responded to ovarian stimulation before receiving the drug.
After treatment, six developed follicles that made it possible to retrieve eggs in response to ovarian stimulation.
Follicles are small sacs within the ovaries where eggs develop.
Professor Angelica Lindén Hirschberg, the study’s first author and a professor at Karolinska Institutet’s Department of Women’s and Children’s Health, said: “The results show that in some women there remains an egg reserve that can be activated when the autoimmune process is suppressed.”
In five women, mature eggs could be frozen or fertilised.
Three later had embryos transferred and all three gave birth to healthy babies.
For safety reasons, the embryo transfers took place no earlier than one year after treatment.
One serious side effect was reported and was linked to the hormone stimulation rather than the immunotherapy.
Women with autoimmune POI commonly have other autoimmune diseases.
All six women who responded to the treatment also had autoimmune Addison’s disease, a condition in which the immune system destroys the adrenal glands.
The study was a proof-of-concept investigation without a control group and involved a small number of participants, meaning the findings must be interpreted cautiously.
A proof-of-concept study is an early investigation designed to assess whether an approach could work before it is tested more widely.
Professor Lindén Hirschberg said: “This is a first step. To determine whether the method is effective and safe, larger, randomised studies are required.”
The research team has launched a larger randomised study.
The work was carried out by researchers at Karolinska Institutet, Karolinska University Hospital and the University of Bergen.
It was funded by organisations including the Swedish Research Council, the Knut and Alice Wallenberg Foundation, the Novo Nordisk Foundation and Region Stockholm.
The researchers reported no conflicts of interest.
POI is also linked to long-term health risks caused by oestrogen deficiency, including osteoporosis, an increased risk of cardiovascular disease, cognitive decline and poorer mental and sexual wellbeing.
Hormone replacement therapy can relieve menopausal symptoms and reduce many of these risks, but no treatment has been reliably shown to restore fertility in women with POI.
Egg donation was previously the only option for women with the condition who wanted to become pregnant.
