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.

India is facing a growing burden of non-communicable diseases (NCDs), with hypertension and diabetes among the major health concerns.
Experts warned that the risk of both conditions rises after 40, often without noticeable symptoms. Increasing age, weight gain, reduced physical activity, stress, dietary habits, and metabolic changes can all contribute to the risk.
Having hypertension and diabetes together is particularly concerning, as their coexistence can increase the risk of heart disease, stroke, kidney damage, retinopathy, and other complications.
Dr. Santosh Gupta, Associate Director - CTVS, Paras Health Udaipur, told HealthandMe that several factors contribute to the rising risk after 40.
“After the age of 40, the risk of hypertension and diabetes increases due to factors such as changes in metabolism, reduced physical activity, weight gain, stress and dietary habits. What makes both conditions particularly concerning is that they can develop silently, without noticeable symptoms, while gradually affecting vital organs,” he said.
He added that uncontrolled hypertension can damage the heart, brain, kidneys, and blood vessels, while diabetes can affect the kidneys, eyes, nerves, and cardiovascular system.
"When both conditions occur together, the risk of heart disease, stroke and kidney complications becomes even higher,” Dr. Gupta added.
Because both conditions can remain silent for years, people may have high blood pressure or blood sugar without knowing it.

A recent hospital-based analysis found that hypertension and diabetes frequently occur together, with their coexistence rising sharply from around age 40 among Indians.
The study, conducted by the Department of Clinical Research and Preventive Health Program at Max Healthcare, analyzed health records of more than 56,000 adults who underwent preventive health check-ups between January 2021 and December 2024.
Nearly 5% of adults had both conditions. Their coexistence increased rapidly from around 40, continued rising until approximately 58 and gradually reached nearly 17% by around age 70.
People with diabetes were nearly four times more likely to have hypertension, while those with hypertension were about 2.5 times more likely to have diabetes.
Dr. Abhaya Indrayan, Biostatistics Consultant, Max Healthcare, said the findings support screening for both conditions rather than assessing them separately.

Experts said that preventive healthcare should go beyond checking for individual diseases. Adults over 40 should routinely assess key cardiometabolic risk factors, including blood pressure and blood sugar.
Screening can help detect hypertension, diabetes or prediabetes early, when lifestyle changes and treatment can help prevent or delay complications.
“This is why regular screening after 40 is important, even for individuals who feel completely healthy. A routine blood pressure check, fasting blood glucose or HbA1c test can help identify hypertension, diabetes or prediabetes at an early stage, when timely lifestyle changes and medical intervention can prevent or delay complications,” Dr. Gupta said.
“Screening should not be viewed only as a diagnostic exercise; it is an opportunity to understand one’s health risks and take corrective measures before the disease begins to cause irreversible organ damage,” he added.
Preventive care also involves addressing modifiable risk factors. Regular physical activity, maintaining a healthy weight, limiting salt, sugar and highly processed foods, getting adequate sleep and avoiding tobacco can help lower the long-term risk.
For those already diagnosed with hypertension or diabetes, regular monitoring and adherence to prescribed treatment are important to reduce the risk of complications.
With the risk of both conditions rising after 40, experts recommend making routine health checks part of regular healthcare—even when there are no obvious symptoms.

Amid the ongoing monsoon season, Delhi-NCR is seeing a rise in H1N1 influenza cases, with Delhi reporting 1,344 cases so far this season.
The figure is nearly six times higher than the 229 H1N1 cases recorded during the same period last year, The Times of India reported.
According to health officials, Delhi recorded around 4,000 influenza cases last year, most of them caused by H3N2. This year, H1N1 is the dominant strain. Both H1N1 and H3N2 are subtypes of Influenza A and spread mainly through respiratory droplets.
H1N1 is a subtype of Influenza A and can cause sudden fever, cough, sore throat, headache, body aches and fatigue. These symptoms can overlap with those of other seasonal influenza strains, COVID-19 and respiratory syncytial virus (RSV), making it difficult to identify the infection based on symptoms alone.
Dr Aijaz Ilmi, Senior Consultant – Metabolic Diseases, Pacific OneHealth Hospital, told HealthandMe that testing is particularly important when fever or respiratory symptoms persist or worsen, especially among older adults, young children, pregnant women and people with diabetes, obesity, heart or lung disease, or compromised immunity.
“With the current rise in H1N1 cases in Delhi, we are also seeing other seasonal respiratory infections, including Influenza A and B, COVID-19, RSV and other respiratory viruses. At the same time, the monsoon season brings an increased risk of mosquito-borne illnesses such as dengue.
“The key message is, don’t panic, but don’t dismiss a persistent fever as ‘just a viral’. Early recognition is particularly important in vulnerable individuals.”
H1N1 can be difficult to distinguish from other respiratory infections because many of them cause similar symptoms.
Dr Sharwari Sudhir Dabhade, Consultant - Internal Medicine, Diabetology & Endocrinology, Madhukar Rainbow Children's Hospital, told HealthandMe that prevention should focus on reducing exposure and maintaining good hygiene. Other measures to reduce transmission include:
Most viral respiratory infections recover with supportive care. However, should seek prompt immediate medical assessment in cases of

People with inflammatory bowel disease (IBD) may face a higher risk of depression, anxiety and other psychiatric disorders years before they are diagnosed with the gut condition, a new study has discovered.
The study, published in Clinical Gastroenterology and Hepatology, found that the risk of psychiatric disorders began rising two to three years before an IBD diagnosis, peaked shortly after diagnosis and remained elevated for as long as a decade.
Researchers from Karolinska Institutet and other Swedish institutions analysed data from 43,862 people with IBD, comparing them with nearly 179,000 individuals from the general population and more than 26,000 IBD-free full siblings.
The sibling comparison was key as it helped researchers examine whether shared genetic or early-life environmental factors could explain any association.

The study found that the risk of developing any mental health disorder was already 15% higher two years before IBD diagnosis. It increased further around the time of diagnosis, reaching a roughly 50% higher risk within the first six months.
Although the risk reduced afterwards, it remained about 19% higher even 10 years after diagnosis. Major depressive disorder, anxiety disorders and substance misuse accounted for much of the increase.
Antidepressant and anti-anxiety medication use also began rising around a year before the IBD diagnosis.
Researchers called for mental health screening to begin early, including during the initial gastroenterology evaluation.
“It is time to actively manage psychiatric conditions in patients with IBD,” said Jiangwei Sun, PhD, the study’s lead author.

IBD includes Crohn’s disease and ulcerative colitis, autoimmune conditions that cause inflammation in the digestive tract.
One possible explanation is the gut-brain axis, the two-way communication system connecting the digestive system and brain.
Inflammation, changes in gut bacteria and abnormal immune activity may affect brain function and overall mood. At the same time, stress and psychological distress can affect the gastrointestinal symptoms.
But researchers caution that the study merely shows an association, not proof that IBD directly causes depression or anxiety.
Some people may experience subtle or unexplained gastrointestinal symptoms before receiving an official diagnosis, while the uncertainty and disruption caused by chronic symptoms could also affect mental health.
The findings follow previous research that shows psychiatric symptoms can surface before the patient is diagnosed with IBD.
A 2023 study examining longitudinal health records found that anxiety and depression occurred more frequently among people who were later diagnosed with IBD.
In a 2024 systematic review and meta-analysis, it was observed that patients with a history of depression may have a small-to-moderate increased risk of subsequently developing IBD, suggesting that the relationship between the gut and mental health could work in both directions.
The new findings therefore signal that mental health symptoms may sometimes arrive years before IBD itself is formally diagnosed in patients.
For doctors, researchers say this highlights the need to treat IBD as more than a digestive disease, with psychological support and screening considered part of long-term care.
