Natural Cycles gets FDA clearance to integrate birth control app with Apple Watch data

Users who own an Apple Watch Series 8, 9, Ultra, or Ultra 2 will be able to import their temperature data from their watch

The fertility-tracking app Natural Cycles has received clearance from the US Food and Drug Administration (FDA) for its use of wrist temperature data from Apple Watch.

The Natural Cycles app is used to help women plan or prevent a pregnancy “naturally”. There are six days each cycle a woman can become pregnant and the app, its developers say, uses an algorithm that analyses daily hormone-driven temperature changes to confirm if the user is fertile that day or not.

To receive their daily fertility status, users can manually take their body temperature or sync temperature data from a wearable device.

With the latest Apple Watch integration, Natural Cycles says users who own an Apple Watch Series 8, 9, Ultra, or Ultra 2 will be able to import their temperature data straight from their device.

Dr Elina Berglund Scherwitzl, Natural Cycles co-founder and CEO, said: “Immediately following the addition of temperature-sensing capabilities to Apple Watch Series 8 and Apple Watch Ultra, our users began asking for this integration so our team began clinical evaluations to validate the quality of the wrist temperature data to determine whether we could deliver Natural Cycles birth control using data from Apple Watch.

“We were thrilled with the results, submitted them to the FDA, and with this clearance are excited to give our users the ability to seamlessly measure using a device many already own and love.

“At a time when birth control accessibility has never been more important, we’re excited to give millions of women who already own a supported Apple Watch access to deeper fertility insights.”

In September 2022, Apple introduced temperature-sensing capabilities to Apple Watch with the release of Apple Watch Series 8 and Apple Watch Ultra.

The smart watch uses the temperature-sensing capabilities to enable users to receive retrospective ovulation estimates and period predictions. However, Apple’s cycle tracking experience is not intended to be used as a form of birth control.

Natural Cycles is currently the only app that has been cleared by the FDA to be used and marketed as birth control.

It received clearance to be marketed as birth control in 2018 through the FDA’s de novo premarket review pathway and was certified in the European Union in 2017. In the UK, however, the NHS does not recommend the app as a birth control method.

While Natural Cycles claims a typical use effectiveness rate of 93 per cent and a perfect use effectiveness of 98 per cent, some argue that the body’s basal temperature must be taken carefully for the algorithm to be correct, and for the app’s result to be effective.

Jana Abelovska, a superintendent pharmacist at Click Pharmacy, encourages users to use the app alongside condoms for extra protection.

“If users miss a temperature reading close to their predicted fertility window, barrier contraception, such as condoms, should be used to avoid accidental pregnancy,” Abelovska told the Independent.

New pregnancy treatment shows promise for at-risk twins

Published

on

A high-powered ultrasound treatment could help identical twins affected by a rare and serious condition during early pregnancy, an initial study suggests.

Twin-to-twin transfusion syndrome, or TTTS, causes uneven blood flow between identical twins who share a placenta.

The imbalance can leave one baby dangerously small and the other too large, putting both babies’ survival at risk.

 

Brioney Garrett’s daughters were in danger before doctors used the world-first treatment to seal the blood vessels causing the problem without an operation.

Nancy and Margo were born healthy and, now aged four, are due to start school.

Researchers from Queen Charlotte’s and Chelsea Hospital tested the non-invasive procedure in 10 women from the UK and elsewhere in Europe after scans detected TTTS during early pregnancy.

Five women needed further treatment, while 12 of the 20 babies survived following the procedure.

The researchers described having a treatment that did not require a needle or telescope to be inserted into the mother’s abdomen as “extremely exciting”.

However, they said larger studies involving more pregnant women were needed before the procedure could be offered more widely.

Garrett described her daughters as “my miracle twins”.

She said: “We were in a very dire situation and I don’t forget that.

“It stays with me always how things could have been. Every day I still count my blessings.”

TTTS affects between 10 and 15 per cent of identical twins who share a placenta, representing around 300 to 400 pregnancies in the UK each year.

The uneven blood flow causes excess fluid to build up around the larger recipient baby, while leaving dangerously little fluid around the smaller donor baby.

Treatment usually involves inserting a needle into the womb to drain some of the fluid or using a laser to seal the connecting blood vessels.

Garrett’s procedure took about 20 minutes. She lay flat while a specially designed machine directed high-powered ultrasound waves at small blood vessels in her placenta.

She said: “It was very quick and pretty painless.”

Christoph Lees, head of fetal medicine at Imperial College Healthcare NHS Trust and professor of obstetrics at Imperial College London, described the research as “very promising”.

He said: “If this could work in a fully-fledged study, it could give hope to a lot of women who otherwise might have to have quite invasive treatment.”

Ultrasound is commonly used during medical scans to produce images of the body, but this procedure uses much more focused waves.

Heat generated by the waves can seal blood vessels about 2mm in diameter and located around 5cm to 6cm beneath the skin.

The procedure blocked blood flow in 90 per cent of the vessels treated during the study, with no unwanted side-effects reported.

Twins Trust, which supported the study, said the approach could make a significant difference for families affected by TTTS.

Helen Peck, head of healthcare engagement and research, said: “Any procedure that is non-invasive and can potentially identify TTTS earlier and improve outcomes for our families with this life-threatening condition could be a turning point.”

Scans carried out weeks after Garrett’s procedure showed that blood flow between the babies had been rebalanced, although other problems developed during the pregnancy.

Garrett said Margo, who had too little fluid around her, “was in a much better position” and that “the strain on Nancy’s heart had eased”.

Nancy and Margo were born at nearly 34 weeks, weighing 3lb 7oz and 3lb 3oz respectively.

Garrett said: “They were both healthy, and Margo wasn’t as small as we worried she was going to be.”

The twins are due to start primary school in September.

Garrett said: “They’re funny, smart, energetic little girls that just fit right in with their age group.”

New reporting tool targets maternal-fetal teams as pregnancy complexity rises

Published

on

A new reporting tool built specifically for obstetrics and maternal-fetal medicine has launched, aimed at teams managing increasingly complex pregnancies with limited time and resources.

Trice Imaging has released Trice Workspace Reporting, which connects imaging, reporting and longitudinal patient data in a single workflow to support faster clinical decision making.

Birth rates are falling worldwide, but pregnancies are getting more complicated. Advanced maternal age, IVF-assisted pregnancies, rising obesity rates and a higher prevalence of hypertension and diabetes mean more cases now require specialist monitoring, advanced imaging and multidisciplinary care.

At the same time, clinical teams are stretched and facing growing administrative demands.

Trice Workspace Reporting brings together customisable reporting, dynamic pregnancy dating and longitudinal patient history with an AI-ready, EHR-interoperable infrastructure, all inside the company’s Tricefy image management platform.

The company says it aims to accelerate standardised and synchronised report turnaround, support timely clinical decisions and improve operational efficiency for fetal medicine services.

“Maternal fetal medicine teams are managing increasingly complex pregnancies while being asked to do more with limited time and resources,” said Mark A. Samii, chief revenue officer at Trice Imaging.

“Trice Workspace Reporting is designed to remove unnecessary friction from reporting by creating a structured digital foundation that supports today’s need for connected clinical workflows.

“It also provides a digital foundation as practices prepare for tomorrow and the evolution of AI-enabled fetal assessment, anomaly detection and outcome prediction technologies.”

Trice Imaging describes its mission as transforming the women’s health journey by connecting physicians, patients and healthcare systems. From independent practices to large hospital ecosystems, it aims to reach the entire women’s health continuum, spanning IVF and reproductive health, maternal-fetal medicine and OB/GYN, and onwards to lifelong women’s health.

For more than 17 years the firm has worked on cloud-based storage, retrieval, display, organisation and exchange of ultrasound medical images and associated information across health environments.

Its wider platform now extends to dynamic clinical reporting, AI-driven workflow optimisation, data analytics and secure patient engagement.

Trice Imaging holds regulatory and data protection clearances in 40 countries. It has offices in Miami and Stockholm, alongside a growing network of global distributors.

Women’s Health has waited long enough for innovation

Published

on

By Dr Fran Conti-Ramsden, clinician at Guy’s and St Thomas’ NHS Foundation Trust, academic at King’s College London, and chief medical officer of MEGI Health.

A woman gives birth. A few days later she goes home, often with a bag of medication for her blood pressure, and then, very often, very little structured follow-up for her heart (cardiovascular) health.

In my clinical work, and through our collaboration with Action on Pre-eclampsia, I see and hear about this postnatal cliff edge again and again, and it still shocks me.

We invest a lot of medical care and attention whilst a woman or birthing individual is pregnant, then, at the very moment emerging evidence suggests we have a window of opportunity to modify long-term health, the support falls away.

That cliff edge is a symptom of a deeper issue: we have come to treat “women’s health” as a synonym for reproductive health. Pregnancy, periods and fertility, important as they are, have crowded out everything else.

Yet the conditions that do most to shorten and limit women’s lives are not reproductive at all.

Cardiovascular disease is the leading cause of death in women worldwide, and it is still too readily thought of as a man’s problem.

Heart disease in women is more likely to be missed and under-treated, in part because for decades women were under-represented in the research that built our knowledge.

Pregnancy makes this vivid.

Conditions such as pre-eclampsia are not only risks to be managed for nine months; they are early warnings about a woman’s future, markers that she is more likely to develop heart disease and high blood pressure in the years to come.

We have the knowledge to act on that. What we mostly do instead is discharge her and look away.

This is exactly the kind of problem better tools should help us solve: spotting risk earlier, supporting women and their clinicians through the vulnerable postnatal window, and providing continuity where the system currently provides a drop due to lack of capacity.

Artificial intelligence and digital health have real potential here; in risk prediction, in monitoring blood pressure at home, and in helping stretched clinicians know who needs attention and when.

And yet this is not where most of the energy is going.

It is far easier to build, fund and scale an app that tracks a cycle than a tool that changes the trajectory of a woman’s heart.

So, innovation clusters at the lighter, lower-risk end of innovation, while the conditions that actually kill and disable women, and moments like the postnatal cliff, stay under-served.

Closing the women’s health gap could add at least a trillion dollars to the global economy each year, the World Economic Forum estimates, but the bigger prize is women living longer, healthier lives.

None of this means technology is a cure in itself. It is a tool, and a tool built carelessly can do harm.

Because women have been under-represented in medical data, systems trained on that data can quietly carry the same blind spots forward, deepening inequalities rather than closing them.

Responsible innovation, with clinical-grade evidence, privacy and equity designed in from the start, and tools built around real clinical pathways rather than bolted on afterwards, is not a brake on progress.

It is the only version of progress worth having.

I am optimistic, because a serious community is forming around exactly these questions and the appetite to get it right is real.

It is why, at MEGI, we are bringing clinicians, researchers, founders, regulators and investors together for our AI × Women’s Health summit on 25 June.

If we keep our focus on the conditions that matter most to women’s lives, and build the tools to meet them responsibly, the postnatal cliff edge could become something else entirely: the moment the system finally catches her and delivers preventative healthcare.

AI × Women’s Health: Innovation, Challenges and Opportunities summit is taking place on Thursday 25 June 2026 at the London Institute for Healthcare Engineering. The event is free and is fully booked and operating a waiting list. Join the waiting list here.
