Can Damaged Sperm Lead To Pregnancy Complications?
Pregnancy is usually a time of happiness and hope, but it also brings in the unexpected. While there is much talk placed on the health of the expectant mother, the quality sperm coming from the father could dramatically change the outcome of pregnancy. The latest study suggests the risks of sperm DNA damage, even increasing the risks of complications preeclampsia and birth prematurity.
In a groundbreaking research study conducted by scientists from Lund University in Sweden, scientists discovered that DNA damage in sperm increases the risk almost up to double that of preeclampsia, this is a dangerous condition that may arise during pregnancies characterized by high blood pressure. In addition, DNA anomalies also increase the risk of premature births, and this further entails increased related adverse health outcomes for infants born through such conditions.
The next step would be to find out which group of men respond best to methods to prevent and treat sperm DNA damage, and to test these methods to prevent pregnancy complications," said Dr. Amelie Stenqvist, a lecturer at Lund University. According to this study, a significant message is put forward that paternal health assumes an important role in a successful pregnancy.
It focused its research on men, specifically whose sperm contained high levels of DNA fragmentation. For instance, some 20% to 30% of babies born via in vitro fertilization have fathers whose sperm contains damaged DNA. The DNA fragmentation index, an indicator to assess the percentage of DNA damage in sperm, indicated that when the percentage of sperm with a DFI above 30% was observed, they had almost no chance of resulting in natural conception. Even a DFI greater than 20% showed that the chances of getting pregnant are highly risky as the risk factor for pregnancy complications like preeclampsia is much high.
Uncommon Complications during Pregnancy
The most alarming complication during pregnancy is preeclampsia. It affects approximately 5% to 8% of pregnancies worldwide, which can cause fatal conditions for both the mother and the baby. The new findings now point out that sperm DNA damage may contribute to this condition, especially if it is due to assisted reproductive techniques such as IVF pregnancies. The research found that a DFI above 20% doubled the risk of preeclampsia from a mere 5% to almost 11% per.
Apart from causing preeclampsia, DNA fragmentation in sperm is also known to increase the risk for prematurity. Most premature babies experience respiratory, neurological, and developmental complications. Therefore, some degree of early intervention might be important for prospective parents.
Some of the rarer, though serious complications include placental abruption, which is the separation of the placenta from the uterine wall and intrauterine growth restriction, a condition by which the baby does not grow normally in the womb. These conditions though rare are potentially catastrophic both to the mother and the child. Results from this study may help in establishing the contribution of the father in such pregnancies.
Further study into sperm DNA damage is of urgent interest with regard to its consequences for pregnancy outcomes. According to Professor Aleksander Giwercman of Lund University in the field of Reproductive Medicine, "the analysis of DFI should be introduced as routine test in all fertility clinics.". "It could give answers to couples who are having difficulties with infertility, but our latest result also shows that DFI analysis can be a method to identify high-risk pregnancies, explained Giwercman.
For many, DNA fragmentation in sperm is often treatable. Common causes are oxidative stress, age, smoking, being obese, and infections. Addressing these elements will likely reduce DNA damage in sperm for men, raising the chances for a healthy pregnancy and baby.
Overall, the study importance should take into consideration paternal as well as maternal health towards reaching for a healthy pregnancy. Though DNA fragmentation in the sperm is supposed to increase the risk factors for complications in pregnancies, the advances into novel treatment approaches and tests are likely to alleviate complications in many families. Thus the findings of this study offer optimism and pave a pathway to more holistic fertility treatments in the future.

Infections accounted for an estimated 2.3 million new cancer cases worldwide in 2024, or about 12% of all cancers diagnosed that year, according to a September 2026 study published in The Lancet Oncology. Among these, Helicobacter pylori (H. pylori), a bacterium that infects the stomach, was associated with an estimated 760,000 cancer cases.
A 2025 study by the International Agency for Research on Cancer (IARC), part of the World Health Organization (WHO), estimated that 76% of the 15.6 million stomach cancer cases expected over the lifetimes of people born between 2008 and 2017 could be attributable to H. pylori infection if prevention efforts do not improve.
Although infections can contribute to cancer development, they are not the only cause. Genetics, age and non-infectious factors also play a role, Dr. Vivek Kaul, Professor of Medicine in the Gastroenterology & Hepatology Division at the University of Rochester Medical Center, told HealthandMe in an exclusive interview.
“I think, generally speaking, I think H. pylori is a well-known carcinogen, mostly responsible for the development of gastric cancer,” Kaul said.
Is Cancer Increasingly Linked To Infections?
The findings highlight the contribution of infectious agents to the global cancer burden. However, Kaul cautioned against concluding that cancer is increasingly being driven by infections.
“But I don't think it's fair to say that, you know, we are moving towards a more infectious etiology for cancer,” he said.
“Cancer is a multifactorial disease state that develops, most commonly develops from genetic and from non-infectious causes,” Kaul added.
He explained that cancer development also depends on the ability of cells to defend themselves against external threats and genetic mutations.
“In many cases, cancer development comes primarily from genetic and age-related issues and boils down to the individual cell's ability, you know, to fight external attacks, such as from H. pylori type of agents or from genetic mutations,” he said.
Kaul also noted that other infectious agents have been implicated in cancer development.
H. pylori is a bacterium that infects the stomach lining and can persist for years. The infection can cause chronic inflammation and damage to stomach tissue, increasing the risk of gastric cancer.
According to scientists at the International Agency for Research on Cancer (IARC), part of the World Health Organization (WHO), H. pylori infection is responsible for an estimated 76% of stomach cancer cases worldwide. The infection often causes no noticeable symptoms, although some people may experience digestive complaints.
The bacterium can spread through contaminated food or water and close contact with infected individuals. In some cases, the infection can cause stomach ulcers. Because many infected people have no symptoms, testing may be needed to identify it.
The World Gastroenterology Organisation's global guidelines state that eradicating H. pylori before precancerous changes develop can help prevent gastric cancer. This evidence supports test-and-treat screening programmes for young adults in countries with a high disease burden and sufficient resources.
Testing can involve blood, breath or stool tests, depending on the clinical context. People diagnosed with the infection can receive treatment to eradicate the bacterium. Follow-up testing can then confirm whether treatment has worked.
Nobel laureate and gastroenterologist Dr Barry Marshall has also highlighted the potential for early treatment to reduce cancer risk.
“H. pylori is much more than an ulcer organism. If the infection persists for many years, it can cause chronic inflammation in the stomach and increase the risk of gastric cancer. That gives us an opportunity because this is a potentially preventable cause of cancer,” Marshall told PTI.
He stressed the need for wider testing, appropriate treatment and follow-up to ensure the infection has been cleared.
Beyond infection-associated cancers, Kaul highlighted the rising incidence of several digestive cancers.
“We know that esophageal squamous cancer is another example where we will be close to a million cases by 2035,” he said, pointing to the burden in East Asia, sub-Saharan Africa and South America, including India.
Kaul also identified liver cancer as a growing concern and noted the rise in colorectal cancer among younger people in Western countries. The increase in colorectal cancer among younger adults in the US contributed to recommendations to begin average-risk screening at age 45 rather than 50.
These trends underline the need to address infectious causes of cancer alongside other risk factors, while improving access to prevention, early detection and appropriate care.

With the increasing use of smartphones, laptops and other digital devices, neck pain and back discomfort are becoming common concerns among people of different age groups. Long working hours, improper sitting positions and excessive screen time are putting additional pressure on the spine. What may begin as mild stiffness in the neck or shoulders can gradually develop into persistent discomfort if ignored.
Poor posture and prolonged screen use are among the common lifestyle factors contributing to neck and back pain.
Many people complain of neck stiffness or back pain despite not being involved in physically demanding activities. On examining their daily routine, we often find that they spend several hours working on computers or looking at their mobile phones without taking adequate breaks. Maintaining the same posture for extended periods can put unnecessary stress on the spine.
The spine is a complex structure made up of vertebrae, intervertebral discs, joints, ligaments and muscles. It supports the body, helps maintain balance and allows movement. However, prolonged sitting and incorrect posture can affect the normal functioning of these structures.
One of the growing concerns associated with digital device usage is ‘text neck’, a term commonly used to describe neck pain and discomfort linked to repeatedly looking down at smartphones and tablets. When the head moves forward from its natural position, the muscles of the neck and shoulders have to work harder to support it. Over time, this may lead to stiffness, muscle fatigue and recurring pain.
Children and teenagers are also vulnerable to posture-related problems because of extended screen time, online learning and gaming. Encouraging them to take regular breaks and participate in outdoor activities can help promote better musculoskeletal health.
The effects of an inactive lifestyle extend beyond the spine. Reduced physical activity can contribute to weight gain, poor muscle strength and an increased risk of metabolic and cardiovascular health problems. Regular movement is therefore important not only for spinal health but also for overall well-being.
Preventing posture-related pain does not necessarily require complicated exercise routines. Small changes in everyday habits can help reduce strain on the neck and back.
Taking short breaks during working hours instead of remaining seated continuously. Standing up, walking around or performing gentle stretches every 30 minutes can help reduce prolonged static loading on the spine.
Workstation ergonomics also plays an important role. People should keep their feet comfortably supported on the floor, maintain a relaxed shoulder position and avoid bending their neck forward for extended periods. The computer screen should be positioned at a comfortable viewing height, while laptop users can consider an external keyboard and mouse to improve their working posture.
Regular physical activity can further support spinal health. Exercises such as bridges, planks and bird dogs can help strengthen the muscles that support the spine when performed correctly. Walking, swimming and cycling are also useful ways to remain active. The World Health Organization recommends that adults undertake at least 150 minutes of moderate-intensity physical activity each week.
People with obesity, diabetes or a family history of spinal disorders should pay particular attention to their daily activity levels and seek medical advice when necessary. Parents should also encourage children to balance screen time with physical activity and healthy movement habits.
Occasional discomfort that improves with movement or a change in posture may not necessarily indicate a serious problem. However, persistent or worsening pain should not be ignored.
Consulting a doctor if neck or back pain continues for several weeks, radiates into the arms or legs, or is accompanied by tingling, numbness or muscle weakness. Pain associated with fever or unexplained weight loss also requires prompt medical evaluation.
Do not rely on painkillers for prolonged periods without professional guidance. Pain relief alone may not address the underlying cause, making an appropriate assessment important when symptoms persist.
Most cases of neck and back pain do not require surgery. Many can improve with appropriate treatment, physical activity and changes in daily habits. The important thing is to identify the cause of the pain and avoid ignoring recurring symptoms
As digital devices become an essential part of modern life, protecting spinal health requires greater awareness of posture, regular movement and healthy screen habits. Simple preventive measures adopted today can help people maintain better mobility and comfort in the long run.

Beyond weight loss and diabetes control, GLP-1 drugs may offer mental health benefits by reducing the need for psychiatric hospital care among people with schizophrenia and type 2 diabetes (T2D), according to a new study published in The Lancet Psychiatry.
The findings showed that treatment with glucagon-like peptide-1 receptor agonists (GLP-1s) was associated with lower risks of psychiatric hospitalization and emergency department visits among people with both conditions.

Researchers from Deakin University and the University of Queensland in Australia analyzed US health records of more than 70,000 adults with schizophrenia and T2D who received treatment between January 2018 and October 2026.
The researchers found that people taking GLP-1 drugs were:
GLP-1 use was also associated with fewer psychiatric emergency department visits. Compared with the same groups, users were:
Further, when the researchers analyzed individual drugs, the association was observed with semaglutide, liraglutide, and tirzepatide, but not dulaglutide.

The researchers cautioned that the observational study cannot establish that GLP-1 drugs directly reduce the need for acute psychiatric care.
They said the medications should not be considered primary psychiatric treatments or prescribed solely to reduce psychiatric hospitalizations and emergency visits.
Instead, the findings point to a potential additional benefit when GLP-1 drugs are prescribed for appropriate metabolic indications as part of integrated cardiometabolic and mental health care.
“The findings suggest that lower psychiatric acute-care use could be a favourable secondary benefit when GLP-1-based therapies are clinically indicated for metabolic management,” the researchers said.
They added that randomized clinical trials and mechanistic studies are needed to determine whether the drugs have a direct effect on psychiatric outcomes. Further research should also investigate their potential benefits in people with schizophrenia who do not have T2D.
Schizophrenia is a serious psychiatric disorder associated with disability, other health conditions, and premature mortality. Cardiometabolic diseases, including T2D, contribute substantially to this burden.
Studies suggest that diabetes may be up to five times more common among people with schizophrenia than among those without the condition. Approximately one in five people with schizophrenia may also have diabetes.
Several factors may contribute to this increased risk, including:
GLP-1 receptor agonists are an established class of medications used to manage T2D and, in some cases, obesity. Their potential role in people with schizophrenia is of growing interest because of the high burden of metabolic disease in this population.
However, whether these medications directly improve psychiatric outcomes remains uncertain.
The latest findings suggest that GLP-1 treatment may be associated with reduced use of acute psychiatric care among people with schizophrenia and T2D. Further clinical trials are needed before any direct mental health benefit can be established.
