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 is often feared as a silent disease, but in many cases, the body does give early warning signs. The challenge is that these signals are either ignored, misunderstood, or detected too late.
A large number of cancer cases are diagnosed at advanced stages—not because symptoms were absent, but because they were overlooked or diagnosis was delayed.
Understanding the early signs and the reasons behind delayed detection can help save lives.
Speaking to HealthandMe, Dr Siddharth Sahai, Director & Unit Head - Medical Oncology, Max Super Speciality Hospital, Dwarka, shared seven signs of cancer that should not be neglected.
1. Unexplained weight loss
Losing weight without trying—especially more than 4–5 kilos in a short time—can be an early sign of cancers such as stomach, pancreas, or lung cancer.
2. Persistent fatigue
Feeling unusually tired despite adequate rest could signal underlying issues like blood cancers or colon cancer. This kind of fatigue does not improve with sleep.
3. Changes in bowel or bladder habits
Chronic constipation, diarrhea, blood in stool, or changes in urination patterns should not be ignored. These may point toward colorectal, bladder, or prostate cancer.
4. A lump or thickening in the body
Any new lump—especially in the breast, neck, or underarms—needs medical evaluation. Not all lumps are cancerous, but it’s important to rule it out early.
5. Persistent cough or hoarseness
A cough lasting more than 2–3 weeks, or voice changes, could be early signs of lung or throat cancer, especially in smokers.
6. Unusual bleeding or discharge
Bleeding between periods, after menopause, blood in urine, or unusual discharge can be warning signs of cancers such as cervical, uterine, or bladder cancer.
7. Non-healing sores or skin changes
Sores that do not heal, changes in moles, or new skin growths could indicate skin cancer or oral cancer (especially in tobacco users).

Dr Sahai also mentioned six common causes of delayed cancer diagnosis
Factors that contribute to late detection include:
1. Lack of awareness
Many people are not aware that these symptoms could be linked to cancer. They often dismiss them as minor issues like acidity, infection, or weakness.
2. Ignoring symptoms due to busy lifestyles
In both urban and rural settings, people tend to delay doctor visits due to work commitments, family responsibilities, or simply hoping the problem will resolve on its own.
3. Fear and denial
The fear of being diagnosed with cancer leads many individuals to avoid medical consultation. Denial becomes a major barrier, especially when symptoms are mild initially.
4. Limited access to healthcare in some areas
In smaller towns and rural regions, access to diagnostic facilities and specialists is still limited. This leads to delays in proper testing and referrals.
5. Financial constraints
Concerns about the cost of investigations and treatment often prevent timely medical attention. Many patients wait until symptoms worsen significantly.
6. Misdiagnosis or delayed referral
In some cases, early symptoms may mimic common illnesses. Without timely screening or specialist referral, diagnosis can be delayed.
Dr Sahai stressed that early detection significantly improves cancer outcomes. Most cancers, if identified in the initial stages, are treatable and even curable. The key lies in listening to your body and acting without delay.
Simple steps like regular health check-ups, cancer screening (such as mammography, Pap smear, or oral screening), and timely consultation can make a crucial difference.
Ignoring symptoms may seem convenient in the short term—but early action can save not just time, but life itself.

Amid the growing burden of hypertension and related heart disease in India, a team of experts has suggested switching to potassium-enriched low-sodium salt substitutes (LSSS).
In India, more than 1 in 4 people have hypertension, and cumulatively, more than 90 per cent of adults with hypertension are either undiagnosed, untreated, or treated but live with uncontrolled hypertension. This burden needs to be tackled on an urgent basis
In view of this, experts from clinical medicine, public health, and nutrition released a consensus statement recommending potassium-enriched LSSS as an effective intervention to reduce hypertension and cardiovascular disease in India.
Current estimates show that Indians consume between 8 and 11 grams of salt (equivalent to 3.2–4.4 grams of sodium) per day, nearly double the WHO’s recommended limit of 5 grams (2 grams of sodium).
High sodium intake is a key driver of elevated blood pressure. At the same time, potassium plays a complementary role by helping counteract sodium’s effects—yet potassium intake in India remains below optimal levels.
With nearly 80 per cent of sodium intake in India coming from salt added during cooking at the household level, experts emphasized that interventions focused on reducing salt use at home can have the greatest impact.
“High-quality research shows India’s high sodium and low potassium intake is a key driver of hypertension and cardiovascular disease. Low-sodium salt substitutes address both—cutting sodium and restoring potassium, which is key to lowering blood pressure. With no change in taste and appropriate safeguards, this is a safe, scalable solution for India’s NCD prevention strategy,” Prof. Vivekanand Jha, Executive Director of The George Institute for Global Health India.
The low-sodium salt substitutes are composed of approximately 70–75 per cent sodium chloride and 25–30 per cent potassium chloride. It reduces sodium intake while increasing potassium consumption, thereby helping to lower blood pressure and reduce cardiovascular risk.
The World Health Organization (WHO), in January 2025, released guidelines recommending potassium-enriched salt to combat hypertension and related heart risks.
The WHO's guideline suggests using K-salt or potassium chloride instead of regular table salt, rich in sodium. It may reduce noncommunicable diseases (NCDs) such as cardiovascular diseases (CVDs) and chronic kidney disease by lowering blood pressure.

It also lowers the risks of other conditions associated with high sodium intake, such as gastric cancer. As per the WHO, every year 80 Lakh people die due to poor diet. Of these, 19 lakh deaths are attributable to high sodium intake.
These alternative salts contain less sodium than regular salt and often include potassium chloride (KCl), with or without other agents, to achieve a flavor similar to regular salt.
Evidence shows potassium - enriched low-sodium salt substitutes are a practical, effective, and scalable solution. The new consensus also marks an important shift from evidence to action, aligned with the Government of India’s commitment to reduce population-level salt intake.
India has committed to a global goal of reducing the average population level sodium intake by 30 per cent by 2030 to help prevent and control non-communicable diseases (NCDs).
While the WHO guidelines urged people to partially replace table salt with potassium, concerns have been raised about the safety of LSSS that contain potassium, because too high a level of blood potassium (hyperkalemia) may be harmful, especially to individuals with impaired kidney function.
Experts noted that potassium is safe for most people, including many with early-stage kidney disease, but maintained that caution is primarily necessary for individuals with advanced stages of kidney disease or when potassium levels are already high.
"While we have enough scientific data supporting the benefits of Low-Sodium Salt Substitutes, the evidence-to-action gap must be closed by treating LSSS as a ' dietary vaccine' to treat hypertension. It is the 'low-hanging fruit' of cardiology, a passive intervention that provides 24/7 cardiovascular protection without requiring patients to actually sacrifice the taste of their traditional diet," said Prof. Ambuj Roy, Department of Cardiology, AIIMS, New Delhi.

Dr. Sandeep Mahajan, Professor, Nephrology, AIIMS, New Delhi, added, “The potential risks of low-sodium salt substitutes are often overstated relative to their population-level benefits. While a small subset of patients—particularly those with advanced kidney disease or on specific medications—require caution, this group is clearly identifiable and can be guided through simple screening and labelling measures".
The expert noted that "nearly 90 per cent of the population can safely benefit from this intervention".
The Consensus recommends priority actions such as:

Every month, millions of women endure painful periods and convince themselves that it is normal. However, the statistics tell a different story. Endometriosis affects about 247 million women worldwide, and nearly 42 million of those are in India alone. Yet, most of them suffer in silence for years before they get diagnosed.
Endometriosis occurs when tissue similar to the uterine lining grows outside the uterus, on the ovaries, fallopian tubes, bowel, or nearby pelvic areas. India accounts for nearly 25% of the global burden of this condition. Even with this staggering number, it remains one of the most underdiagnosed issues in women’s health.
- Pain severe enough to disrupt daily activities, work, or school
- Cramping that starts days before your period and continues after it ends
- Pain during or after intercourse
- Painful bowel movements or urination around your cycle
- Heavy or irregular bleeding
- Unexplained fatigue, bloating, or lower back pain
These are your body's warnings, not signs of weakness or something to just endure.
The Cost of Waiting
The statistics on diagnostic delays are alarming. On average, there is a 7 to 9-year delay between the first symptoms and a confirmed endometriosis diagnosis worldwide. Endometriosis affects 10–15% of all women of reproductive age and up to 70% of women with chronic pelvic pain, yet many spend nearly a decade seeing multiple doctors before anyone identifies the true cause.
This delay leads to serious consequences. The monthly natural conception rate in women with endometriosis drops to just 2–10%, compared to 20% in women without the condition. Longer delays are directly linked to more severe disease, greater psychological distress, and tougher fertility challenges.
Too many women come to me after years of being told their pain is normal. By the time they reach us, many are already dealing with advanced-stage disease.
Your pain is real, and it deserves a real answer. Do not wait, consult a specialist. Early diagnosis truly changes everything.
If your periods are affecting your quality of life, your body is asking you to listen. The sooner you seek help, the better your outcomes. Consult a specialist today. Take the first step towards a pain-free life.
