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.

Former US Senator Ben Sasse is battling Stage 4 pancreatic cancer that has spread around his body. According to his doctors, he now has four types of cancer: lymphoma, vascular, lung cancer, liver cancer, and pancreatic cancer.

Speaking to The New York Times’s “Interesting Times” podcast, the Republican Senator from Nebraska reflected on his life and impending death.

Sasse was diagnosed with Stage 4 pancreatic cancer in December 2025, which remained in the shadows for a long time. Until late October, Sasse had no symptoms. But it started with a lot of back and abdominal pain. Initially, he thought it was due to “some ab muscles pulled from stupid forms of training”.

His doctors thought Sasse had some undiagnosed celiac disease or some dairy allergy. However, a full body scan in December revealed that Sasse’s “torso is chock-full of tumors.”

“In mid-December, I got a three- to four-month life expectancy,” he was quoted as saying.

“They told me over the course of the next couple of days that I already have five forms of cancer: lymphoma, vascular, lung cancer, bad liver cancer, and pancreatic, where it originated,” the former senator added. “So, it was pretty clear that we’re dealing with a short number of months left to live.”

Sasse represented Nebraska in the Senate for eight years before resigning to become the president of the University of Florida in July 2024.

During the interview, Sasse said his condition has improved since last December -- his pain is 80 percent reduced.

"I’m at Day 99 or something since then, and I’m doing a heck of a lot better than I was doing at Christmas," he said.

However, the former senator noted that he deals with nausea, as well as bleeding on his face due to intake of the investigational new drug daraxonrasib.

During the interview, the former lawmaker’s face was covered in dried blood.

Death A Wicked Thief, Says Ben Sasse

Sasse, a father of three, said he felt a “heaviness” with respect to realizing he did not have much time left with his family.

“I didn’t like the idea of my 14-year-old son not having a dad around at 16,” he remarked. “I didn’t like the idea of my daughters, who are 22 and 24, not having their dad there to walk them down the aisle. I felt a real heaviness about that.”

However, the Nebraska Republican said he has “continued to feel peace about the fact that death is something that we should hate.”

“We should call it a wicked thief,” he continued. “And yet, it’s pretty good that you pass through the veil of tears one time and then there will be no more tears, there will be no more cancer.”

What Is Pancreatic Cancer? Know The Warning Signs

Pancreatic cancer has long been one of the toughest challenges in oncology. With a five-year survival rate hovering around 13 percent and recurrence rates approaching 80 percent after treatment, the odds have historically been stacked against patients.

The prevention and early detection remain vital.

Experts warn that pancreatic cancer often masquerades as common ailments, delaying diagnosis. Here are some early symptoms that should never be ignored:

  • Abdominal or back pain that worsens over time or eases when leaning forward.
  • Unexplained weight loss without changes in diet or exercise.
  • Jaundice, including yellowing of the eyes and skin, sometimes with intense itching.
  • Changes to urine or stool, such as dark urine or pale, greasy stools.
  • New-onset diabetes without obvious risk factors.
  • Persistent fatigue unrelated to poor sleep or lifestyle
These symptoms often appear in combination and warrant immediate medical attention — particularly for those with a family history of pancreatic cancer.

Want To Stave Off Dementia Risk? 3 Simple Lifestyle Changes May Help, Says Study

Updated Apr 10, 2026 | 07:31 AM IST

SummarySitting for more than eight hours a day increased dementia risk by almost 30 percent, at the same time being regularly active, even just going for a walk every day, decreased dementia risk by an average of 25 percent.

Three simple lifestyle changes, such as regular physical activity, cutting down sedentary time, and improving sleep duration, may significantly boost your brain's cognitive abilities and reduce the risk of dementia later in life, according to a new study.

Dementia is a neurodegenerative condition affecting an estimated 55 million people globally. It is characterized by a decline in memory, thinking, and social abilities.

Together, the three simple lifestyle changes cut down the risk of late-onset dementia by 25 percent.

Published in the open-access journal PLOS One, the systematic review and meta-analysis of over 69 prospective cohort studies involving millions of cognitively healthy adults aged 35 and above showed the potential benefits of lifestyle behaviors such as regular physical activity, cutting down sedentary time, and improving sleep duration.

According to the Alzheimer’s Association, a person’s overall risk for developing Alzheimer’s disease—the most common form of dementia—is about 11 percent. However, the study found that with the simple suggested lifestyle changes, the average person’s risk decreases to approximately 8 percent.

The study emphasized that people do not need elaborate and expensive longevity hacks to stay mentally sharp as they age.

The reduction is “fairly comparable to the effect sizes sometimes seen with medications for chronic diseases,” said Akinkunle Oye-Somefun, a researcher at York University in Toronto, who led the study, NBC News reported.

Sitting For Long Periods Worst For Your Brain

The findings showed that avoiding sitting for longer periods had the greatest effect and can have a long-term benefit for the brain.

Sitting for more than eight hours a day increased dementia risk by almost 30 percent, at the same time being regularly active, even just going for a walk every day, decreased dementia risk by an average of 25 percent.

Long sitting hours can also spike a person’s risk of other conditions such as cardiovascular disease, diabetes, and obesity, all of which in turn raise dementia risk.

Getting between seven and eight hours of sleep each night also had a greater benefit on the brain.

The risk of dementia increased by 18 percent among those who slept less than seven hours, while sleeping more than eight hours per night also raised the risk of the neurodegenerative disease by 28 percent.

Importantly, moderate physical activity “offsets dementia risks even when other risk factors are present,” said Oye-Somefun, NBC News reported.

However, “many people assume that being physically active cancels out the harm of sitting for long periods. It doesn’t,” Oye-Somefun said. “We shouldn’t do one of these things alone; we should do them all.”

What Is Dementia?

Dementia is an umbrella term used to describe a significant decline in mental function that is serious enough to affect everyday life. It commonly impacts memory, thinking, and reasoning skills.

Dementia itself is not a single disease but a collection of symptoms caused by underlying conditions such as Alzheimer’s disease or vascular dementia.

Common signs include

  • memory problems,
  • confusion,
  • difficulty finding words,
  • changes in mood or behavior,
  • trouble completing familiar tasks.

These symptoms usually worsen over time and are not considered a normal part of ageing. Although there is no cure, treatment options can help manage symptoms, and early diagnosis plays an important role in care planning.

Why A Persistent Cough Can Be An Early Warning Sign Of Lung Cancer: Doctors Explain

Updated Apr 10, 2026 | 12:01 AM IST

SummaryIf you are a non-smoker who is leading a healthy lifestyle and has no medical conditions other than a persistent cough, then you must visit your doctor right away, advised the experts.

It was during the COVID-19 pandemic that Annabelle Gurwitch, an American author, actress, and television host, developed a "a little persistent cough".

Suspecting it to be a COVID symptom, Annabelle went for a check-up. Her doctor alarmingly informed her about something suspicious on her lungs. Soon after, an X-ray and a biopsy confirmed her diagnosis of stage 4 cancer.

But, here's the catch. Annabelle is a non-smoker. She also lived a healthy lifestyle and exercised every day, and felt like she was in really good health, besides the persistent little cough.

HealthandMe spoke to health experts to understand how a persistent cough signals the risk of lung cancer.

If you, too, are a non-smoker who is leading a healthy lifestyle and has no medical conditions other than a persistent cough, then you must visit your doctor right away, advised the experts.

"A persistent cough can be an early warning sign of lung cancer, especially when it shows specific features rather than behaving like a routine respiratory illness," Dr Sameer Khatri, Principal Director - Medical Oncology, Max Super Speciality Hospital, Patparganj, told HealthandMe.

The doctor noted that the cough becomes suspicious when it persists beyond three weeks without a clear cause or fails to respond to standard symptomatic treatment such as cough syrups, bronchodilators, etc.

"A change in a pre-existing smoker’s cough—for example, becoming more frequent, severe, or different in character—is particularly important. In non-smokers, a new, unexplained chronic cough should not be ignored," Dr. Khatri said.

Certain associated symptoms further strengthen the suspicion of cancer. The most significant is hemoptysis, the coughing up of blood or blood-stained mucus, even if minimal.

Other red flags include

  • unintentional weight loss,
  • chest pain,
  • breathlessness,
  • hoarseness,
  • recurrent pneumonia in the same lung region.
  • age >40 years,
  • smoking history, occupational exposures.

Persistent cough: TB Vs Lung Cancer

Persistent cough also signals the risk of tuberculosis (TB) -- the world's most deadliest infectious disease. Understanding the differences between these two causes is critical for early diagnosis and timely treatment.

Dr Seema Jagiasi from MOC Cancer Care Center told HealthandMe that the cough in TB may sometimes produce blood-tinged phlegm, but it is usually associated with signs of infection, such as fatigue and a general feeling of illness.

TB is more common in younger populations and in individuals with weakened immunity or poor living conditions.

"In contrast, a cough associated with lung cancer tends to be more insidious. It may start as a dry, persistent cough that gradually worsens over time. Unlike TB, it may not initially present with fever or infection-related symptoms," the doctor explained.

One of the key differences lies in progression and response to treatment.

TB is treatable with a course of antibiotics, and symptoms often improve within weeks of starting therapy. However, a lung cancer-related cough persists or worsens despite routine medications.

Dr Jagiasi emphasized that any cough lasting beyond three weeks, especially when accompanied by alarming symptoms, should not be ignored.

"Early investigations, such as chest imaging and further diagnostic tests, can help distinguish between the two conditions," the doctor said.

While both TB and lung cancer may present with a persistent cough, their underlying causes, associated symptoms, and progression differ significantly.

The health experts called for more awareness and the need for timely medical evaluation for the effective management of the disease.
