Women with infertility history at greater risk of cardiovascular disease after assisted conception
2025-05-09
(Press-News.org) Women who experience infertility are more likely to develop heart and blood vessel conditions later in life, with younger women and those who undergo fertility treatments at a greater risk. The findings, presented at the first Joint Congress between the European Society of Paediatric Endocrinology (ESPE) and the European Society of Endocrinology (ESE), highlight the importance of considering a woman’s reproductive history when assessing her long-term heart health.
Approximately one in every six people of reproductive age worldwide is estimated to experience infertility in their lifetime. Treatment of infertility often involves in-vitro fertilisation (IVF) and other types of assisted reproductive technology (ART). While previous studies have shown infertility may be an early marker of cardiovascular risk, the data have been conflicting and no comprehensive review has yet provided a broad assessment of the possible impact of medically assisted reproduction.
In this study, Greek researchers from the National and Kapodistrian University of Athens looked at 21 studies, involving 178,828 women with infertility and 3,398,781 women without fertility issues, that associated female infertility with cardiovascular disease later in life. The researchers found that women with infertility have a 14% increased risk of developing conditions affecting the heart or blood vessels, a 17% increased risk of heart disease and a 16% increased risk of a stroke when compared to women without an infertility history. In addition, the risk of cardiovascular disease increased by 20% in younger women with infertility, especially those under 40, and by 4% in women who underwent assisted reproductive technology treatments.
“This is the largest meta-analysis to not only examine the potential link between a history of infertility in women and cardiovascular risk but also the impact of assisted reproductive technologies on their likelihood of developing future cardiovascular events,” said lead researcher Dr Elena Armeni. “By gathering data from many studies, our work adds strong evidence to a growing field and suggests that infertility could be an early warning sign for future heart health issues.”
Dr Armeni added: “Recognising infertility as a potential early marker for cardiovascular disease could help doctors identify women who may need closer monitoring or preventive strategies earlier in life. It also raises important questions about the long-term effects of fertility treatments like assisted reproductive technology (ART) treatments.”
“Some earlier studies did not find a strong association between infertility and heart disease, so in our meta-analysis we addressed this by including only high-quality studies and performing sensitivity analyses based on study design and participant age,” said Dr Armeni.
The researchers now plan to follow women with and without infertility over time to improve understanding of how fertility history impacts their heart health. “We aim to create a well-designed prospective study that will closely examine the relationship between different causes of infertility, exposure to assisted reproductive technologies and long-term cardiovascular outcomes,” said Dr Armeni.
“We hope to clarify the biological mechanisms behind these associations and identify which groups are at greatest risk. Ultimately, this will help shape future guidelines for early prevention strategies and improve cardiovascular care for women with a history of infertility.”

Computer simulations help materials scientists and biochemists study the motion of macromolecules, advancing the development of new drugs and sustainable materials. However, these simulations pose a challenge for even the most powerful supercomputers.
A University of Oregon graduate student has developed a new mathematical equation that significantly improves the accuracy of the simplified computer models used to study the motion and behavior of large molecules such as proteins, nucleic acids and synthetic materials such as plastics.
The breakthrough, published last month in Physical Review Letters, enhances researchers’ ability to investigate the motion ...

MAY 9, 2025, NEW YORK – A Ludwig Cancer Research study has identified a key mechanism by which advanced ovarian cancers suppress anti-tumor immune responses and resist immunotherapies. Led by Ludwig Princeton’s Lydia Lynch and reported in the current issue of Science Immunology, the study details how ascites fluid—produced in large quantities as ovarian cancer spreads from the ovaries into the abdomen and its organs—sabotages cytotoxic lymphocytes, a class of immune cells that kill cancer cells.
“Although ascites fluid has long been known to be immunosuppressive, it has not been clear what precisely gives it that property,” explained Lynch. “We discovered ...

Millions of kilometres of rivers around the world are carrying antibiotic pollution at levels high enough to promote drug resistance and harm aquatic life, a McGill University-led study warns.
Published in PNAS Nexus, the study is the first to estimate the scale of global river contamination from human antibiotics use. Researchers calculated that about 8,500 tonnes of antibiotics – nearly one-third of what people consume annually – end up in river systems around the world each year even after in many cases ...

Most scientists look at DNA behavior in isolation, without considering how matter within a cell interacts with DNA
Researchers observed DNA strand separation preceding replication and repair suppressed by molecules pushing strands together
Findings challenge the standard in biochemical practice of heating DNA to separate strands
EVANSTON, Ill. --- By creating a more true-to-life representation of DNA’s environment, researchers at Northwestern University have discovered that strand separation — the essential process a “resting” double helix undergoes before it can initiate replication or make repairs — may take more mechanical force ...

What happens when trailblazing engineers and industry professionals team up? The answer may transform the future of computing efficiency for modern data centers.
Data centers house and use large computers to run massive amounts of data. Oftentimes, the processors can’t keep up with this workload because it’s taxing to predict and prepare instructions to carry out. This slows the flow of data. Thus, when you type a question into a search engine, the answer generates more slowly or doesn’t provide the information you need.
To remedy this issue, researchers at Texas ...

New research led by Irish scientists has uncovered how lipid-rich fluid in the abdomen, known as ascites, plays a central role in weakening the body’s immune response in advanced ovarian cancer. The findings offer new insights into immune suppression in ovarian cancer and open promising avenues for future immunotherapy approaches.
Over 70% of patients with ovarian cancer are diagnosed at an advanced stage, often presenting with large volumes of ascites. This ascites fluid not only supports the spread of cancer throughout the abdominal cavity but also ...
