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.

When Back Pain Isn’t Just Back Pain: Recognising Warning Signs of Kidney Cancer

Updated Jun 16, 2026 | 05:00 PM IST

SummaryWhen uncertainty exists, simple tests such as a urine examination and ultrasound can provide clarity. Early detection remains the key to effective treatment and significantly better outcomes.

Back pain is one of the most common health complaints worldwide, affecting a large proportion of adults at some point in their lives. In most cases, it is caused by benign musculoskeletal issues such as muscle strain, poor posture, or disc-related problems, and it tends to improve with rest, physiotherapy, or simple medication. However, not all back pain originates from the spine. In some situations, pain felt in the lower back or flank region may be linked to underlying kidney conditions, including kidney cancer. As renal cell carcinoma often progresses silently in its early stages, symptoms may be delayed, making it important to recognise when back pain is unusual.

Why Kidney Cancer Can Cause Back Pain

Dr Raj Nagarkar, Chief Surgical Oncologist at HCG Manavata Cancer Centre, Nashik, said, "The kidneys are located deep in the upper abdomen, on either side of the spine, just below the rib cage. When a tumour develops in this region, it can cause pain through several mechanisms. As the tumour grows, it may stretch the kidney’s outer fibrous capsule, leading to a persistent, dull ache in the flank area between the ribs and hip. In some cases, fragile tumour blood vessels may bleed internally or form clots that obstruct urine flow, resulting in sudden, sharp pain that can resemble renal colic. Larger tumours may also press on surrounding nerves or structures, producing discomfort that may be mistaken for back or abdominal pain."

Unlike musculoskeletal pain, which typically improves with movement or rest, kidney-related pain is often constant, may worsen at night, and does not respond well to routine pain relief or physiotherapy.

Red Flags When Back Pain Needs Further Diagnosis

While back pain alone is rarely a sign of kidney cancer, certain accompanying symptoms should raise concern. One of the most important warning signs is blood in the urine, which may appear pink, red, or dark brown and can sometimes be intermittent. Persistent flank pain associated with a palpable mass under the ribs may indicate more advanced disease. Unexplained weight loss, ongoing fatigue, or a general sense of weakness can reflect systemic illness. Some patients may experience intermittent fever without infection, new-onset high blood pressure, or swelling in the legs and ankles due to impaired venous drainage. Anaemia-related symptoms such as dizziness, breathlessness, or pallor may also be present. When back pain persists beyond a few weeks and is accompanied by any of these features, further medical evaluation is strongly recommended.

Differentiating Musculoskeletal Back Pain from Kidney Cancer Pain

It is also important to distinguish kidney-related pain from common musculoskeletal back pain. Mechanical back pain is usually localised to the lower back, may radiate to the legs, and often begins after physical strain or injury. It tends to improve with rest, heat application, or physiotherapy. In contrast, kidney cancer pain is typically one-sided, located higher in the flank below the ribs, and develops gradually without a clear trigger. It is often persistent, may disturb sleep, and is not relieved by standard pain management approaches. Unlike spinal pain, it is more likely to be associated with systemic symptoms such as haematuria, weight loss, or fatigue.

Who Is at Higher Risk?

Certain individuals are at higher risk of developing kidney cancer and should be particularly attentive to persistent flank pain. Risk factors include smoking, which significantly increases exposure to kidney-damaging toxins, obesity, long-standing hypertension, chronic kidney disease or dialysis, and a family history of kidney cancer or genetic conditions such as von Hippel-Lindau disease. Occupational exposure to industrial chemicals like trichloroethylene or cadmium may also contribute to risk. When multiple risk factors are present, even mild or persistent symptoms should not be ignored.

Diagnosing Kidney Cancer

If warning signs are suspected, doctors typically begin evaluation with simple and non-invasive tests. A urine analysis can detect microscopic or visible blood, while blood tests help assess kidney function, anaemia, and calcium levels. Imaging plays a crucial role, with ultrasound often used as the first-line investigation, followed by a contrast-enhanced CT scan for detailed evaluation of tumour size and spread. In selected cases, a biopsy may be performed, although it is not always required before treatment.

Treatment and Outcomes

Treatment outcomes for kidney cancer have improved significantly in recent years. In early-stage disease, partial nephrectomy allows removal of the tumour while preserving healthy kidney tissue, often using minimally invasive or robotic techniques that support faster recovery. In more advanced cases, targeted therapies and immunotherapy help control disease progression and improve quality of life, with many patients able to maintain daily activities during treatment. For small, slow-growing tumours in selected individuals, active surveillance may be an appropriate option.

Listening to the Warning Signs

While most back pain is benign and related to musculoskeletal causes, persistent or unusual pain, especially when accompanied by symptoms such as blood in the urine, unexplained weight loss, or systemic changes, should not be ignored. Kidney cancer often develops silently, and early signs can be subtle. Unlike muscular pain, which is typically movement-related and self-limiting, kidney-related pain is deeper, more persistent, and often associated with other warning features.

Vanessa Trump Begins Second Stage of Breast Cancer Treatment

Updated Jun 16, 2026 | 06:00 PM IST

SummaryBreast cancer is also the leading cause of cancer mortality among women worldwide and the most common cancer diagnosed overall, accounting for approximately 2.3 million new cases and 670,000 deaths annually, according to the WHO

Vanessa Trump, the former wife of Donald Trump Jr., has announced that she is beginning the second stage of her breast cancer treatment.

In an Instagram post, Trump said she has spent the past four weeks recovering from surgery.

She said she was “grateful to be healing and moving forward.” “Sending love, strength, and hope to everyone fighting this battle,” she wrote.

The 48-year-old mother of five first revealed her breast cancer diagnosis in late May, saying she was working closely with her medical team to develop a treatment plan.

However, Vanessa Trump has not disclosed the type of breast cancer she has been diagnosed with or provided details about the next phase of her treatment.

What Is Breast Cancer?

Breast Cancer occurs when abnormal cells in the breast grow uncontrollably, often beginning in the milk ducts or lobules. It remains the most commonly diagnosed cancer among women worldwide.

Breast cancer is also the leading cause of cancer mortality among women worldwide and the most common cancer diagnosed overall, accounting for approximately 2.3 million new cases and 670,000 deaths annually, according to the World Health Organization.

Every year, breast cancer accounts for about 30% of all new cancer cases in US women. The average risk of a woman in the US developing breast cancer sometime in her life is about 13 per cent.

A recent study published in The Lancet Oncology projected that global breast cancer cases could rise to more than 3.5 million annually by 2050.

Major Lifestyle Risk Factors

In 2023, 28 percent of the global breast cancer burden (6.8 million years of healthy life lost to disability, illness, and early death) was linked to six potentially modifiable risk factors.

These include:

  • High red meat consumption
  • Tobacco use and second-hand smoke exposure
  • High blood sugar levels
  • High body mass index (BMI)
  • Excessive alcohol use
  • Low physical activity

Breast cancer patients who are also obese or have type 2 diabetes experience more aggressive cancer growth and worse outcomes. Prior studies have shown that weight loss treatment and surgery following a breast cancer diagnosis are associated with improved heart health and increased survival.

Tips For Maintaining Breast Health

Regular checkups are the cornerstone of early breast cancer detection.

According to the World Health Organization (WHO), early identification of breast abnormalities greatly increases the chances of effective treatment and survival.

  • Women who ignore screenings may face delayed diagnosis, which can complicate treatment.
  • Schedule regular mammograms and clinical breast exams
  • Perform monthly self-examinations
  • Know your family medical history
  • Maintain a healthy weight and active lifestyle
  • Pay attention to hormonal health
  • Watch for physical changes such as persistent pain, swelling, or skin dimpling.

Heatwaves and Extreme Heat: Nearly two in three children worldwide (1.5 billion) are exposed to heatwaves that are becoming more frequent, longer-lasting, or more severe. Additionally, 1.2 billion children are exposed to extreme heat conditions.

Fires and Dust Storms: An estimated 206 million children are exposed to frequent and severe wildfires, while 123 million are exposed to sand and dust storms.

Malaria: More than two in five children globally—around one billion—live in areas with exposure to malaria, a climate-sensitive disease whose transmission is influenced by temperature and rainfall patterns.

Air Pollution: An estimated 2.3 billion children—almost all children worldwide—live in areas where air pollutants are detectable.

“These exposures pose serious risks to children’s health, learning and well-being, particularly where access to cooling, safe water and health care is limited,” the report noted.
