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.

Mental health issues among doctors remain a serious but rarely discussed concern within the medical community, said Dr. Cyriac Abby Philips, popularly known on social media as the LiverDoc.
In an exclusive interaction with HealthandMe, the noted hepatologist highlighted the rising cases of burnout, depression, and suicide among healthcare professionals and the urgent need to address them.
He stated that doctors are among the major communities affected by mental health disorders, although the topic is often ignored within the profession.
“We have had very senior doctors die by suicide because of burnout,” he said, citing incidents involving highly successful doctors recently reported from parts of India, including Kerala.
Liver Doc stressed that addressing doctors’ mental health is as important as treating patients’ mental health.
“A doctor who has good mental health will be a much better ally for the patient when it comes to treatment,” he said.
He also urged the medical community and regulatory authorities to introduce more interventions and support systems to prevent burnout and mental health disorders among doctors.
According to him, the emotional burden of treating critically ill patients and witnessing deaths regularly can deeply affect healthcare professionals.
“It’s depressing to treat patients and see them die. It’s depressing to see another human die,” he said.
The expert noted that doctors should find ways to openly discuss and process emotional stress and mental health struggles.
Dr. Philips also addressed the issue in his recently released book, The Liver Doctor: Stories of Love, Loss and Regeneration.
He told HealthandMe that he has “very thoroughly and in very raw format addressed in the book” the mental health disorders affecting doctors, as it directly impacts patient care.
“Like every other doctor, I have also gone through that, and it's depressing to treat patients and see them die. I have this book to channelize that, and I feel less burdened when I do that, but other doctors also should find ways to do this. So this book also tells doctors to be more open about their mental health,” he said.
Doctors in teaching hospitals often endure long, unregulated shifts with little time for rest, especially during residency. Such exhausting work conditions not only increase the risk of medical errors but also significantly contribute to burnout, emotional exhaustion, and mental health problems among young doctors.
As per a recent nationwide survey on doctors’ mental health and morale, nine in ten doctors said they would not want their children to become physicians.

The study, conducted by the Debabrata Mitalee Auro Foundation, surveyed 1,208 doctors across metropolitan cities and smaller towns over six months and found deep levels of burnout, fear of violence, and rising medico-legal anxiety among medical professionals.
Further, the Parliamentary Standing Committee on Health and Family Welfare also raised concerns over “excessive continuous duty hours” for junior and senior resident doctors in April.
In its latest report, the panel warned that fatigue-driven errors and burnout could compromise care.
The Panel recommended that the government introduce and strictly enforce a formal “Clinical Duty Hours Regulation” policy. This would mandate fixed rest periods and monitored duty rosters, with oversight mechanisms to prevent violations.

India’s cell and gene therapy ecosystem is beginning to attract a different kind of attention that is driven not just by healthcare demand, but by proprietary science and platform-led innovation.
For investors, however, the larger story may not be the funding round itself. It may be the problem the company is trying to solve.
CAR-T therapies have transformed outcomes for several difficult-to-treat blood cancers globally. But despite strong initial responses, relapse remains one of the field’s biggest limitations. One reason is antigen escape, which means cancer cells can change the markers that therapies use to identify them, making them harder to detect over time.
In an analysis of 4,129 CAR-T treated patients, relapse remained a substantial issue after single-target therapy, with 42.1% of relapses associated with loss of the CD19 target itself. The finding points to a larger issue: precision may not be enough if therapies lose visibility over time.
The response increasingly appears to be a move toward multi-target and more durable platforms. A bispecific CAR-T platform designed to recognize more than one tumor marker, to reduce relapse is crucial.
The science itself is becoming increasingly platform-oriented. Beyond broader targeting, recent work explored why immune cells themselves lose effectiveness over time and identified pathways associated with stronger persistence and memory. While still early, the broader implication is that future therapies may need to be designed not only to attack disease, but also to remain active longer.
For India, that creates a larger opportunity. Historically, advanced therapies such as CAR-T have remained expensive and heavily dependent on technologies developed elsewhere. The aim is to significantly reduce treatment costs while building indigenous capabilities across design and manufacturing.
The shift matters because biotech investing is increasingly moving beyond services and generics toward intellectual property and platform science. The transition from bedside observations to translational platforms may be where the next phase of healthcare innovation and investment gets built.

Colon cancer, medically known as colorectal cancer, was historically typical for people aged 50 or older. However, in recent years, the cancer that forms in the tissues of the large intestine has been increasing in prevalence in young adults. As many as one in five colorectal cancer patients today falls into this younger age group.
Now, a study published by the American Society of Clinical Oncology shows that marathons, which are one of the most celebrated physical activities, may be increasing the risk of the disease.
The team at Inova Schar Cancer Institute in Virginia, US, initiated the study after observing multiple “ultramarathoners” present to their cancer center with advanced colorectal cancer.
To probe the link, they recruited 100 runners to undergo colonoscopies — the gold standard for screening and preventing colorectal cancer. The team then looked at runners ages 35 to 50, who had either completed at least five marathons or two ultramarathons (any runs of 50 kilometers or more).
Presenting the findings at the 2025 American Society of Clinical Oncology (ASCO) annual meeting, Dr. Timothy Cannon, an oncologist at the Institute, stated that

Almost always, colon cancers start as small growths called polyps or precancerous lesions on the inner lining of the colon or rectum.
Moreover, the study found that the rate of advanced adenomas nearly tripled among the marathon runners, compared to the general population, at 4.5 -6 per cent.
In general, running and other forms of exercise are known to reduce the risk of developing colon and other cancers. At the same time, exercise-induced gastrointestinal injury is also believed to be associated with reduced blood flow to the intestines during long-distance running.
Notably, to date there is no evidence that definitively shows running causes polyps.
The new study presents a correlation — an increasing relationship between long-distance running and advanced adenomas. It does not prove that running directly causes the adenomas.

The new results suggest that “intensive long-distance running is a risk factor for advanced adenomas of the colon", said Dr. Timothy, in the paper. The team also called for "refining screening strategies" for marathon runners.
It is because runners put their bodies through a lot, which can raise the risk of chronic inflammation, enabling cancerous cells to grow.

The American Cancer Society notes that colorectal cancer is a cancer that starts in the colon or the rectum. Colorectal cancer impacts around 1.9 million people every year, noted the World Health Organization (WHO) as per its 2022 data.
It is a disease of the large bowel and a type of cancer that originates from the rectum or colon. A person's colon, cecum, rectum, and anus make up the large intestine.
According to experts, if you are above 45 years of age or have high-risk factors, you need to take the initiative to be screened, as the symptoms appear late, impacting treatment outcomes.
The common red flags for colorectal cancer include:
