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.

Fever is one of the body's most common warning signals. In most cases, particularly among children, it is caused by a simple infection and resolves within a few days. However, when fever keeps returning repeatedly, follows a pattern, or occurs alongside other concerning symptoms, it may signal an underlying health condition that requires medical attention.
Dr. Hemalata Arora, Director of Internal Medicine at Nanavati Max Super Speciality Hospital, Mumbai, told HealthandMe that a recurring fever refers to repeated episodes of elevated body temperature that are separated by days, weeks, or even months during which a person feels completely well.
While recurrent fevers can sometimes result from common viral infections, especially in children exposed to school environments, daycare settings, or seasonal illnesses, persistent or unexplained episodes warrant further investigation.
The expert stated that understanding the pattern of fever is often one of the most important clues in determining the cause.
Dr. Diksha Goyal, Consultant in Internal Medicine at Marengo Asia Hospitals, Gurugram, told HealthandMe that a recurrent fever can occur when body temperature rises to 38°C or higher and reappears after improving or occurs intermittently over time.
Several medical conditions may cause recurring fever, including:
1. Chronic Infections such as tuberculosis (TB), urinary tract infections
2. Autoimmune Diseases
3. Immune System Disorders
4. Cancers, particularly blood-related cancers
5. Certain Viral Infections

While recurrent fever is not always dangerous, the experts emphasize that certain accompanying symptoms require prompt medical evaluation.
Dr. Arora notes that urgent attention is needed if recurring fever is associated with:
Dr. Goyal added that persistent cough, swollen lymph nodes, and unexplained body pain can also indicate an underlying condition requiring medical treatment.
These symptoms may point toward serious infections, immune system disorders, blood-related diseases, cancers, or inflammatory conditions in which the body's defense system triggers repeated inflammation without a clear infection.
Another important warning sign is a fever that continues to recur despite treatment. According to Dr. Arora, repeated courses of antibiotics without a confirmed diagnosis should raise concern. In some cases, medications themselves can trigger fever, making a detailed medication history an important part of the evaluation.
The goal is not to panic but to seek timely medical assessment. Check for swollen lymph nodes, rashes, signs of infection, or evidence of systemic inflammation.
The experts noted that early medical evaluation can help identify the underlying cause, prevent complications, and ensure appropriate treatment. With timely diagnosis and proper management, many causes of recurrent fever can be effectively treated, allowing individuals to maintain their health and daily activities.

Tobacco use remains a global epidemic and one of the leading preventable causes of death worldwide. Despite a strong desire among many users to quit, relapse rates remain alarmingly high. A new study by researchers at the All India Institute of Medical Sciences (AIIMS), New Delhi, suggests that yoga could be a valuable tool in helping people quit tobacco.
To evaluate the effectiveness of yoga in tobacco cessation, researchers led by Dr Gautam Sharma, Department of Cardiology and Centre for Integrative Medicine and Research, AIIMS, conducted a meta-analysis of five randomized controlled trials (RCTs) published up to September 2024.
The review included adults aged 18 years and older who used any form of tobacco, excluding vaping products. Participants were randomly assigned to yoga either as a standalone intervention or alongside conventional cessation treatments.
The primary outcome assessed was the 7-day point prevalence abstinence (7PPA), a standard measure of smoking cessation. Secondary outcomes included quality of life, depression, anxiety, and mood states.
The findings suggest that “yoga may serve as a moderately effective intervention for tobacco cessation, with an estimated effectiveness of around 50 per cent”, the team said in the paper.

Researchers found that active yoga styles such as Hatha, Vinyasa, and Iyengar yoga improved abstinence rates by helping reduce stress, depression, and negative emotions often associated with tobacco withdrawal.
Pranayama, or yogic breathing exercises, was found to reduce cravings and negative affect, making it easier for participants to cope with withdrawal symptoms.
The review also highlighted the importance of addressing psychological factors linked to tobacco addiction, including perceived stress, anxiety, depression, and emotional distress—all of which are known contributors to relapse.
While some studies reported stronger psychological benefits than others, overall evidence suggests yoga may support emotional well-being during the quitting process.

Researchers believe yoga may help manage tobacco addiction through several biological mechanisms.
Nicotine stimulates nicotinic cholinergic receptors in the brain, triggering the release of neurotransmitters that produce pleasurable and rewarding effects. During withdrawal, stress-related hormones increase, leading to anxiety, cravings, and emotional discomfort.
Yoga appears to counter these effects by shifting the body from a state of sympathetic nervous system dominance ("fight or flight") to parasympathetic dominance ("rest and digest").

This shift may reduce activity in the hypothalamic-pituitary-adrenal (HPA) axis, lower cortisol levels, and decrease stress hormone production, helping individuals better manage cravings and withdrawal symptoms.
The team also noted that controlled breathing techniques can significantly influence emotional regulation, with voluntary breath control accounting for substantial variations in emotional states such as anger, fear, and joy.
India alone has more than 270 million active tobacco users. Given the widespread use of smokeless tobacco in the region—and the limited effectiveness of standard cessation medications for these users—yoga could offer an accessible, culturally familiar, and low-cost complementary approach, the researchers stressed.
While the results are encouraging, researchers also cautioned that larger and more standardized studies are needed.

Every day, hospitals care for patients whose survival depends on a simple yet irreplaceable resource—donated blood. A mother experiencing severe bleeding after childbirth, a child with thalassemia requiring regular transfusions, a cancer patient undergoing chemotherapy, or a victim of a road traffic accident may all rely on timely access to safe blood.
Despite medical advances, blood remains unique. It cannot be manufactured or artificially replicated. It can only come from healthy individuals who choose to donate. This makes blood donation one of the most vital contributions a person can make to healthcare and society.
It is important to understand that the impact of a single donation extends far beyond what most people imagine.
When a person donates whole blood, it is separated into components—red blood cells, platelets, and plasma. Each component serves a different purpose. Red blood cells carry oxygen and are essential in treating anemia and blood loss. Platelets help control bleeding and are critical for patients undergoing chemotherapy. Plasma contains proteins and clotting factors required for managing bleeding disorders.
Because these components can be used independently, a single donation has the potential to benefit multiple patients with different medical conditions. One act of donation can therefore support several lives.
A common misconception is that blood is needed only during emergencies or disasters. In reality, the demand for blood is constant. Patients with chronic conditions such as thalassemia require regular transfusions throughout their lives. Cancer treatments, major surgeries, organ transplants, complicated pregnancies, and trauma care all depend on a steady and reliable blood supply.
Unlike many medical resources, blood components have limited shelf lives. Platelets can only be stored for a few days, and red blood cells have a defined storage period. This means blood stocks must be continuously replenished. A stable blood supply cannot be created overnight—it depends on regular and voluntary donations throughout the year.
The safest and most reliable blood supply comes from voluntary donors who give blood without expectation of reward. However, maintaining this supply is an ongoing challenge. It requires not only recruiting new donors but also encouraging previous donors to return.
Many individuals who donate once do not return, often due to lack of awareness, time constraints, or fading motivation. Yet every regular donor begins as a first-time donor. A positive first donation experience plays a key role in building long-term commitment.
Hospitals, workplaces, and community organizations play a crucial role in promoting donation through awareness campaigns, outreach programs, and well-organized blood donation drives. Sustained engagement is essential to ensure that donors remain connected to this life-saving cause.
Blood donation is not just a medical act—it is a powerful expression of social responsibility. Most donors never meet the individuals they help, yet they donate willingly to support someone in need. This anonymous act of giving reflects compassion, empathy, and a shared sense of humanity.
People are motivated to donate for many reasons. Some are driven by altruism and the desire to help others. Others are influenced by personal experiences, community values, or encouragement from family and peers. Awareness campaigns and social engagement can also play a significant role in shaping attitudes towards donation.
Understanding these motivations is important because it helps design more effective strategies to encourage both first-time and repeat donors.
Despite its importance, many eligible individuals hesitate to donate due to fear or uncertainty. Concerns about pain, weakness, or safety are common. However, blood donation is a carefully regulated process conducted by trained healthcare professionals.
Donors undergo screening to ensure that the procedure is safe for both themselves and the recipient. The donation itself takes only a short time, and most people can resume normal activities soon afterward. Efforts to improve donor comfort and reduce anxiety have further enhanced the overall donation experience.
For many first-time donors, the greatest takeaway is a sense of satisfaction and pride in having contributed to saving lives.
One of the greatest challenges in maintaining a stable blood supply is ensuring a continuous flow of new donors. As regular donors age or become ineligible, new volunteers are needed to sustain the system.
Encouraging first-time donors is therefore critical. With the right experience and awareness, a first-time donor can become a lifelong contributor, potentially helping dozens of patients over the years. Simple follow-up communication and continued engagement can significantly improve donor retention.
Families, educational institutions, workplaces, and healthcare providers all have a role to play in encouraging individuals to take this first step.
Blood is more than a medical resource—it is a gift that cannot be bought, manufactured, or stored indefinitely. It represents hope, survival, and the generosity of one human being towards another.
Behind every successful surgery, every recovering patient, and every saved life, there is often an unseen donor whose contribution made that outcome possible.
A single donation may take only a few minutes, but its impact extends far beyond a single individual. It supports families, strengthens healthcare systems, and builds a culture of care and compassion within communities.
The message is simple: if you are eligible, consider donating. Your one unit of blood may help many—and could make the difference between life and loss for someone in need.
