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.

Higher temperatures in the US could increase heat-related heart disease by 200 per cent by 2050, according to an alarming study.
The research, published in JAMA Cardiology, predicts rising temperatures driven by climate change will dramatically increase heat-related heart disease in the US.
It is already known that extreme heat is detrimental to heart health and can potentially trigger heart attacks and other cardiovascular events.
"But this study is the first to map out exactly how bad the problem could get—county by county, across the US. It also highlighted how states with lower median household incomes are likely to face higher heat-related heart disease burden," said Gokul Parameswaran, research associate at the Case Western Reserve School of Medicine's Cardiovascular Research Institute and the study's lead author.
Researchers analyzed heart disease data in each county in the contiguous US from 2010 to 2016 to develop projections through 2050.
They found that the Pacific Northwest has the highest heat-related heart disease rate in the country. Southern states, however, are projected to see the steepest increases by 2050.
"Climate change is not just an environmental issue—it is a health equity crisis, and prioritizing vulnerable communities must be at the center of any heat mitigation strategy," said Salil Deo, associate professor in the Department of Surgery.

The study also found that aging — independent of temperature increases — will contribute an additional 34 per cent increase in heat-related heart disease by 2050, simply because there will be more older adults by then.
The study comes amidst more frequent heat events in the US, which is also lasting longer, and the temperatures during heat events are going up.
The past 10 years, from 2015 to 2024, were the hottest on record globally. But in cities across the United States, the average rate of extreme heat events increased from two per year in the 1960s to 10 per year between 2010 and 2020, according to Center for Climate and Energy Solutions (C2ES), a Washington-based NGO.

Additionally, as of 2024, the average length of heat-wave season in the US has increased by 46 days since the 1960s.
According to the Centers for Disease Control and Prevention, when temperatures rise, the heart must work harder to keep the body cool, and the likelihood of developing sudden clots in the bloodstream increases.

This extra stress on the heart due to high heat may lead to heart attacks or sudden worsening of heart disease, especially in the elderly or those with prior heart conditions.
"Climate change is not a distant, abstract threat," said Sanjay Rajagopalan, director of the Cardiovascular Research Institute and chief of Cardiovascular Medicine at University Hospitals Harrington Heart & Vascular Institute.
"It is a present and growing danger to the hearts of every American, and it is coming for the most vulnerable among us first. The choices made today about greenhouse gas emissions, urban planning, and health care policy will determine whether tens of thousands of Americans live or die from heat-related heart disease by 2050," he added.

Diabetes is not only a disorder affecting blood sugar levels, but it also increases the risk of heart disease. People who have diabetes are more prone to get affected by heart attack, stroke, high blood pressure, and blockage of arteries than people without diabetes. Because of this strong link, diabetes care needs a focus on both blood sugar control and heart care.
One of the biggest improvements in diabetes care is the use of GLP-1 receptor agonist therapies. These medications not only help to control sugars but also reduce the risk of heart disease. When a person combines GLP-1 treatment along with a healthy lifestyle, they can improve their overall well-being and lead a good quality of life.
Type 2 diabetes and heart disease are interlinked. Diabetes increases heart disease risk by 2 to 4 times. Over a period of time, when the sugars are chronically high, blood vessels and nerves that support the heart get damaged. Many individuals with diabetes also have additional risk factors, such as:
These conditions can make a person vulnerable to a heart attack and stroke. Studies show that people with Type 2 diabetes are nearly twice as likely to develop heart disease compared to those without diabetes.
GLP-1 receptor agonists are medications to control high blood sugar in people with type 2 diabetes. These therapies help by:
GLP-1 therapies help control blood sugar. Beyond this, these treatment regimens provide many more benefits. Research shows that these medications can reduce the risk of major cardiovascular events such as heart attack and stroke.
In addition, GLP-1 therapies help in weight reduction. Obesity is also linked to diabetes and heart disease. Hence, GLP-1 therapies help to reduce weight and the risk of developing heart diseases.
Medications are important in controlling blood sugars. However, the medication therapies need to be combined with a healthy lifestyle, which can remain the foundation of diabetes and heart disease care.
A balanced, healthy plate can improve blood sugar, cholesterol, and blood pressure levels. Individuals with diabetes are encouraged to include:
Whole grains
Vegetables and fruits
Lean proteins
Nuts and seeds
Healthy fats
By restricting sugars, processed and ultra-processed foods, extra salt, and unhealthy trans-fats, one can reduce weight and support heart health.
Regularized physical activity routines help improve insulin sensitivity and strengthen the heart. Activities like walking, cycling, swimming, yoga, and strength training can help reduce the risk of heart disease. Experts generally recommend at least 150 minutes of moderate exercise every week.
Even small amounts of weight loss can improve blood sugar control and reduce stress on the heart. The combination of GLP-1 therapies, healthy lifestyle, controlled eating, and regular exercise gives better long-term results.
Type 2 diabetes and heart disease are closely interlinked, making complete diabetes care essential. GLP-1 therapies are changing diabetes management by offering benefits beyond glycemic control, including heart protection and weight reduction.
However, tablets and medicines alone cannot do all the work. Healthy lifestyle changes, such as balanced nutrition, regular physical activity, and proper weight management, must contribute equally. GLP-1 therapies and lifestyle changes can significantly reduce heart-related risks and improve overall well-being in individuals with Type 2 diabetes.

Multiple Sclerosis (MS) is a chronic neurological condition in which the immune system attacks the central nervous system, leading to symptoms such as fatigue, chronic pain, bladder disturbances, gait imbalance, and blurry vision, among others. These symptoms fluctuate, progress over time, become life-limiting, and are not always outwardly visible.
Growing evidence shows that early diagnosis and timely initiation of high-efficacy therapies (HETs) can slow disease progression, reduce relapses, and preserve long-term neurological function. For many individuals living with MS, the struggle goes beyond simply managing their condition. It is also about whether the full impact of the disease is adequately recognized and understood by policymakers, healthcare systems, and the public at large.
Although MS is recognized as a disability under the Rights of Persons with Disabilities (RPwD) Act, 2016, people living with MS (PwMS) continue to face difficulties accessing disability-related support because their symptoms are not always consistent, visible, or measurable during assessment. This is particularly relevant in a condition like MS, where some of the most disabling symptoms remain invisible.
The effects of MS extend far beyond mobility issues alone. Fatigue, brain fog, memory problems, neuropathic pain, bladder dysfunction, visual disturbances, and emotional strain can significantly hinder a person's ability to work, engage socially, manage responsibilities, and fully participate in everyday activities.
One of the less understood aspects of MS is cognitive impairment, which affects a significant proportion of PwMS. MS causes inflammation in the brain and contributes to brain volume loss, thereby slowing processing speed, affecting concentration, impairing memory, and making planning or multitasking increasingly difficult. Even routine activities such as maintaining conversations, remembering instructions, or completing everyday tasks may become mentally exhausting.
Because many of these symptoms are episodic, variable, or invisible, PwMS may sometimes delay seeking specialist care, while the impact of the disease may also be underestimated by those around them. Yet, MS disease activity can continue even when symptoms appear intermittent or mild.
In MS, treatment decisions regarding the early initiation of the appropriate therapy (platform disease-modifying therapy versus high-efficacy therapy) can meaningfully influence long-term outcomes and quality of life.
Because slowing disease progression often requires highly potent intervention, evaluating a drug’s long-term safety profile becomes just as critical as its efficacy. Certain therapies may carry a risk of progressive multifocal leukoencephalopathy (PML)—a rare and potentially fatal viral brain infection that occurs under severe immunosuppression. Therefore, choosing a high-efficacy treatment with a favorable long-term safety profile is paramount.
MS is inherently unpredictable. A person may appear physically stable during one evaluation but experience significant neurological difficulties during a relapse or disease flare-up.
In clinical practice, neurologists evaluate MS through disease progression, relapse patterns, imaging findings, and the EDSS scale (a standardized method used to quantify and measure the level of disability in PwMS).
Improving understanding of invisible symptoms in MS is important not only for social awareness but also for enabling patients to access timely care. Greater clarity, consistency, and sensitivity in approaches to chronic neurological conditions can help ensure that PwMS are better supported across healthcare, workplace, and social settings.
Earlier diagnosis, timely intervention, and stronger recognition of the day-to-day realities of living with MS can together help patients preserve dignity, maintain independence, and achieve better long-term outcomes.
