Hormone sensor could streamline IVF process
A hormone sensor being developed in Australia could help reduce fertility treatment costs and patient pain during IVF.
When preparing for egg collection or an embryo transfer, IVF patients rely on clinicians to closely monitor hormone levels to ensure the procedure is timed precisely when progesterone, oestradiol and luteinising hormone levels are optimal, giving the patient the best chance at conception.
Currently, blood tests are the primary method of measuring progesterone levels, requiring patients to undergo multiple blood draws at a laboratory during certain stages of their menstrual cycle.
However, this approach has several limitations.
For example, if testing falls on a weekend, when most labs are closed, IVF providers are forced to choose a less optimal testing time, potentially affecting treatment precision.
University of Melbourne alumni Edgar Charry and Muhammad Umer, whose partners have lived experience of infertility, created a reproductive health solution by developing a biosensor that can detect progesterone and oestradiol levels using fluid found in the skin, rather than in the blood.
Their startup company Symex Labs has partnered with the University of Melbourne to translate their research into a commercial product.
“Previous research shows nearly all hormones that exist in blood, are also present in interstitial fluid,” said Symex Labs co-founder Charry.
“Interstitial fluid is clear fluid just under the skin that sits between cells, delivering nutrients and carrying away waste.”
“Our biosensor will eventually be worn as a patch and will work by penetrating the skin using small microneedles to attract progesterone molecules in the patient’s interstitial fluid.
“These molecules will bind to the surface of the probe, generating electrical activity. The technology then translates the electrical activity to progesterone levels, ultimately informing the IVF clinical team if the patient is ready for embryo transfer.
“This data will be sent directly to the clinic’s monitoring system, allowing IVF nurses to review the results and advise the patient.”
Monash IVF research director associate professor Mark Green said that, for Monash IVF, the investment in Symex Labs aligns with the company’s focus on innovation and improving the patient journey.
“This technology will save patients time and money as they can conveniently wear the patch in the comfort of their own home, resulting in fewer visits to the clinic and fewer painful injections,” associate professor Green said.
“The biosensor would also be a gamechanger for women living in regional areas, who often have to travel long distances for blood draws.”
As the exact amount of progesterone in interstitial fluid is not well understood, Symex Labs is conducting a world-first clinical study at Monash IVF to establish baseline levels by benchmarking them against concentrations measured in blood samples.
Researchers say their hormone tracking technology also has wider clinical applications beyond the IVF sector.
“Our wearable hormone biosensor has strong potential well beyond fertility care, particularly in PCOS management, perimenopause and menopause symptom management, where continuous hormone insight can replace today’s indirect, symptom-based tracking,” said Symex Labs co-founder Muhammad Umer.
“By integrating directly with consumer health apps, the technology can enable personalised, data-driven management of chronic hormonal conditions and life-stage transitions that currently lack real-time biomarkers.
“For example, if a woman’s oestrogen is going up and down constantly, that’s often a sign that she is getting into that stage, so having access to this health information could help women implement lifestyle changes earlier.”
The research has received A$2.5m in funding from the federal government, the University of Melbourne’s Genesis fund, Monash IVF, RMIT and Breakthrough Victoria.
The first in-human pilot study is expected to get underway within the next 12 months, with commercialisation plans slated for early 2028.
Onto Health has acquired Levy Health, a fertility software company providing precision diagnostics and patient intake for reproductive medicine.
The acquisition, fuelled by Onto Health’s US$20m Series A fundraise in April, supports its plan to build scalable, tech-enabled infrastructure for reproductive medicine.
Onto founder Roohi Jeelani, MD, called it the first of several moves in the company’s expansion strategy in a LinkedIn post, adding that there was “more coming soon”.
She said: “This isn’t just an acquisition, it’s proof of how we’re building Onto: physician-led, tech-enabled, and built to scale without losing the personal touch fertility patients deserve.”
Headquartered in Chicago, Onto Health combines evidence-based fertility care with artificial intelligence-driven diagnostics, clinical automation and longevity science.
AI-driven diagnostics use software to analyse patient information and support clinical decision-making, rather than replace clinicians.
Levy Health, founded in Berlin with US offices in San Francisco, helps medical providers identify endocrine disorders more quickly and helps clinics streamline fertility workups.
Endocrine disorders affect the body’s hormone system, which can influence ovulation, menstrual cycles and fertility.
Co-founder Caroline Mitterdorfer said joining Onto would expand Levy Health’s fertility care tools to more clinics and patients, helping physicians focus on patient care.
Onto opened its first clinic in Chicago in February, with plans for three more in the greater Chicago area.
The company said in April that it would use its new funding, led by Artis and Humania, to support additional operations in the US and expand into the Gulf Cooperation Council.
The Gulf Cooperation Council includes six Arab states bordering the Persian Gulf.
Softening ageing ovaries could help women remain fertile for longer, early animal research suggests.
Fertility declines with age for several reasons, including poorer egg quality, fewer ovarian follicles and the gradual stiffening of ovarian tissue.
Existing fertility treatments, including hormone therapy and in vitro fertilisation, mainly address hormonal imbalances or help eggs mature or become fertilised.
Scientists are now examining whether changing the physical structure of the ovaries could provide another route for future fertility treatments.
Stuart A. Cook, of the Cardiovascular and Metabolic Disorders Programme at Duke-National University of Singapore Medical School, published an accompanying commentary on the research.
Researchers led by Shixuan Wang at Huazhong University of Science and Technology in Wuhan, China, collected healthy ovarian tissue from younger, middle-aged and older women.
They also examined samples from patients with polycystic ovary syndrome, known as PCOS, premature ovarian insufficiency, or POI, and endometriosis.
PCOS is a hormonal condition that can disrupt ovulation. POI occurs when the ovaries stop working normally before the age of 40, while endometriosis causes tissue similar to the womb lining to grow elsewhere in the body.
Tests of protein levels and gene activity found higher levels of the inflammatory protein interleukin-11, or IL-11, in ageing and diseased ovaries.
In laboratory experiments, the researchers exposed ovarian fibroblasts to IL-11. Fibroblasts are cells that produce connective tissue.
The protein caused the cells to produce excess collagen, a structural material that can build up during scarring and make tissue stiffer.
The researchers then genetically modified mice so they could not respond to IL-11. The animals developed less ovarian stiffening and maintained better ovarian function as they aged.
Similar results were seen in mouse models of PCOS and POI caused by chemotherapy.
In the final part of the experiment, older mice and rats were injected with a nanoparticle treatment containing small interfering RNA, or siRNA, designed to switch off IL-11.
The treatment made the animals’ ovaries less stiff and improved fertility.
Pregnancy rates among older mice rose from 25 per cent to 50 per cent, while average litter sizes also increased.
More rats treated with the therapy became pregnant and produced larger litters.
The approach remains highly speculative and will require considerably more research before its safety or effectiveness in women can be established.
However, the researchers said blocking the inflammatory pathway could eventually form the basis of new fertility treatments.
They said: “We propose that anti-IL-11 therapy represents a promising translational strategy for delaying ovarian ageing.”
