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.

Cancer treatment has long been thought to be unsuccessful among people of advanced age, and older adults are often left out of clinical decisions.
While they may face more surgical complications, a new study proved that even people aged over 80 can still safely have surgery and be cured. It showed that the overall health of a patient matters more and that age must not be the only criterion to rule out surgery.
The study, published in The Lancet Regional Health – Americas, showed that surgery for lung cancer is safe in elderly patients aged 80 and above, especially when the cancer is in an early stage.
Researchers at the Icahn School of Medicine at Mount Sinai and the Mount Sinai Tisch Cancer Center in the US found that they can recover like young cancer patients as well as live longer like them.
“As our population ages, more patients over 80 are being diagnosed with early-stage lung cancer, yet they are often not considered for surgery,” said Raja M. Flores, Chair of the Department of Thoracic Surgery at Mount Sinai Health System.
“Our findings show that when patients are carefully selected based on their overall health, not just their age, they can tolerate surgery well and experience excellent long-term outcomes,” he added.
The study findings are based on a study of 884 patients with early-stage lung cancer, including 114 people who were age 80 or older.
The researchers examined surgical outcomes and quality of life in patients with early-stage non-small cell lung cancer, comparing those aged 80 and older with younger patients.
The results showed that older patients lived just as long as younger patients after surgery. While some older patients had more complications right after surgery, most patients in both groups felt better over time, and their quality of life improved within a year.
The study noted that early detection in older patients may be key. The researchers called for screening guidelines to include patients who are over 80 years old based on these findings.
Lung Cancer is one of the most common and serious types of cancer. It is also the leading cause of cancer-related deaths worldwide, with approximately 2.5 million new cases and 1.8 million deaths reported in 2022.
According to the American Cancer Society, lung cancer mainly occurs in older people. Most people diagnosed with lung cancer are 65 or older; a very small number of people diagnosed are younger than 45.
The average age of people when diagnosed is about 70.
It is also the leading cause of cancer death in the US, accounting for about 1 in 5 of all cancer deaths.
In many cases, there are no symptoms; however, one must look out for these:
The two main types of lung cancers are:
Non-small-cell lung cancer (NSCLC): This is the most common form, making up about 80–85% of all cases. NSCLC includes three subtypes:

Cancer is not just a problem of elderly people anymore. In India, there has been an increased number of cases where individuals under the age of 40 are diagnosed with various forms of cancer. Even if there are fewer cases of this medical condition among younger people, this fact does not change the fact that one-fifth of all cancer patients in India are younger than 40 years.
Breast cancer, colorectal cancer, head and neck cancer, as well as blood cancer, are some types of cancer that become more common at a younger age. Among the most alarming statistics, the incidence of colorectal cancer in people aged 30-40 should be mentioned. Moreover, the fact that breast cancer becomes evident nine years earlier in Indian women in comparison with Western women must also be noted.
There is a wide variety of factors that contribute to this problem. These are the following:
Early detection saves lives. Some warning signs to look out for are:
Not only does it take time to diagnose cancer cases in young patients due to low suspicions, but these cancers also create an additional burden on people during their prime earning period.
There needs to be a paradigm shift in our understanding of this problem. First of all, we have to understand that cancer affects patients irrespective of their age, and therefore, when you experience some symptoms of cancer, do visit a doctor to get your condition checked out.
The key is maintaining healthy practices like balanced nutrition, exercising, not smoking, and limiting consumption of alcohol.

It often begins in the most ordinary way—someone sits down to enjoy a meal and suddenly feels a sharp swelling under the jaw or near the ear.
The pain intensifies with every bite, creating a strange pattern: eat, swell, hurt; stop eating, and the swelling slowly settles.
For many people, this puzzling cycle is caused by something surprisingly small—a salivary stone. Though typically no larger than a few millimeters, these tiny mineral deposits can cause significant discomfort and, if untreated, repeated infections. Fortunately, modern medicine has transformed how this condition is managed, replacing traditional gland removal surgery with a minimally invasive technique known as sialendoscopy.
Saliva is something most of us rarely think about, yet it plays a vital role in everyday life. It helps us chew and swallow food, begins the process of digestion, keeps the mouth moist, and protects teeth from decay. Salivary stones, medically termed sialolithiasis, develop when minerals—primarily calcium—gradually crystallize inside these ducts.
Over time, these crystals accumulate, forming hard, chalk-like structures that partially or completely block the flow of saliva. When saliva becomes concentrated—often due to dehydration, reduced fluid intake, or medications that decrease saliva production—minerals are more likely to settle and crystallize.
Slow flow or stagnation within the duct allows these tiny deposits to grow. Previous infections, inflammation, or minor scarring can narrow the duct, further encouraging stone formation. The process is gradual and often silent until the blockage becomes significant.
The symptoms are distinctive. Pain and swelling typically occur during meals, when the glands are stimulated to produce more saliva. If a stone is blocking the duct, saliva cannot escape into the mouth. Pressure builds within the gland, causing swelling and a throbbing ache. The swelling may reduce after some time as saliva slowly seeps past the obstruction, only to recur at the next meal.
In some cases, patients notice a dry mouth, an unpleasant taste, or even pus discharge if infection develops. Because the symptoms come and go, many people delay seeking medical help, assuming it is a temporary issue.
Diagnosis today is far more straightforward than it once was. A doctor may sometimes feel a stone during a physical examination inside the mouth or beneath the jaw. Ultrasound scanning is a simple and painless way to detect most stones, while CT scans are useful for identifying deeper or smaller ones.
However, the real breakthrough in both diagnosis and treatment has been sialendoscopy. This technique involves introducing a very thin endoscope—about the size of a delicate wire—directly into the natural opening of the salivary duct inside the mouth. The surgeon can then visualize the duct system from within, identify the exact location of the stone, and in many cases remove it during the same procedure.
Not long ago, treatment options were far more invasive. When stones were deeply lodged or infections recurred, surgeons often removed the entire affected gland.
For the submandibular gland, this required an incision in the neck, a hospital stay, and a recovery period that could last weeks. There was also a significant risk of nerve injury, which could affect tongue movement or lower lip function. While gland excision effectively eliminated the stone, it also meant permanent loss of that gland’s function.
For what is essentially a small obstructing stone, the operation was often disproportionate to the problem. Gland removal also meant a permanent scar on the neck, which can cause significant facial deformity.
The advent of sialendoscopy has dramatically changed this landscape. Through the natural duct opening inside the mouth, the surgeon gently widens the duct and introduces the miniature camera. Continuous saline irrigation keeps the view clear.
Once the stone is located, tiny micro-instruments such as baskets or graspers are used to retrieve it. Larger stones can sometimes be fragmented using a LASER before removal.
In addition to extracting stones, sialendoscopy allows the surgeon to dilate narrow ducts, wash out debris, and treat inflammatory conditions. The procedure typically takes less than an hour, is often performed as a day-care surgery, and leaves no external scar.
The benefits of sialendoscopy are substantial. The most important advantage is gland preservation. Instead of sacrificing an entire gland, the obstruction alone is addressed, allowing normal saliva production to continue. There are no visible scars because the procedure is performed entirely through the mouth.
Recovery is typically quick, with most patients resuming normal activities within a day or two. Complication rates are lower compared to open surgery, and success rates are high—often exceeding 90 to 95 percent in appropriately selected cases. Even when stones are larger or located deeper within the gland, sialendoscopy can often be combined with a small intraoral incision, still avoiding external scars and major surgery.
Sialendoscopy and its allied approaches can now tackle almost any stone, whether it’s in the duct or in the gland, with utmost precision, leaving behind a fully functional gland. Despite conventional learnings, even intraglandular stones, large stones, and patients with multiple stones can be effectively treated using this novel technique.
Prevention, while not always possible, can reduce risk. Staying well hydrated helps maintain healthy saliva flow. Good oral hygiene minimizes infection and inflammation within the ducts. Early evaluation of recurrent swelling can prevent chronic damage. Individuals who take medications that reduce saliva production should be particularly mindful of fluid intake and regular dental care.
The story of salivary stones is ultimately one of medical progress. What was once managed through the removal of an entire gland can now often be treated with a fine endoscope and delicate instruments. The transformation has reduced pain, shortened recovery times, minimized complications, and preserved natural gland function.
For patients, it means less anxiety and more confidence in seeking care early. For surgeons, it represents the success of innovation guided by a simple principle: treat precisely, preserve whenever possible, and restore normal function with the least disruption.
Salivary stones may be small, but their impact can be significant. Thanks to sialendoscopy and the expertise of pioneers in the field, patients today have access to safer, more conservative, and highly effective treatment options. In modern salivary gland care, the focus is no longer on removing the gland—it is on saving it.
