Womb lining linked to repeated miscarriages

Published

on

Problems with the womb lining before pregnancy may help explain why some women experience multiple miscarriages despite having healthy embryos, UK researchers have found.

The study, which analysed over 1,500 biopsies from more than 1,300 women, identified a recurring issue with a biological process called the decidual reaction.

This monthly transformation of the womb lining prepares it for potential pregnancy.

When the process is faulty or becomes dysregulated, it creates a less stable environment for implantation, increasing the risk of early pregnancy loss.

Researchers found that the abnormal response in the womb lining recurred across menstrual cycles far more frequently than would be expected by chance.

 Dr Joanne Muter, lead author from Warwick Medical School, said: “This is about identifying preventable miscarriages.

Many women are told they’ve just had ‘bad luck’, but our findings show that the womb itself may be setting the stage for pregnancy loss, even before conception takes place.

The findings also revealed that experiencing one miscarriage increases the likelihood of abnormal womb lining responses in subsequent cycles.

Around one in six pregnancies end in miscarriage, mostly before 12 weeks.

Professor Jan Brosens is professor of obstetrics and gynaecology at Warwick and UHCW NHS Trust and scientific director at Tommy’s National Centre for Miscarriage Research.

Brosens said: “It is well-established that chromosomal errors in embryos account for the rise in miscarriage rates in women older than 35 years.

“This study shows that each miscarriage increases the risk of an embryo implantation in an abnormal womb lining, regardless of age.

“Thus, the frequency of one of two events – abnormal embryo or abnormal decidual reaction – happening over hundreds of menstrual cycles determines the likelihood of miscarriage in each individual woman.

Importantly, we now have the tools to screen for the risk of preventable miscarriage and to evaluate treatments that improve the womb lining before pregnancy.

A diagnostic test has been developed to assess molecular signals in the womb lining, indicating whether the decidual reaction is functioning normally.

The test is being piloted at University Hospital Coventry and has already supported over 1,000 patients.

Onto Health acquires diagnostics software company Levy Health

Published

on

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 ovaries could extend fertility as women age, study suggests

Published

on

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.”
