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.

Breastfeeding is important not only for babies' health and nutrition but also for protecting mothers from serious diseases, the World Health Organization (WHO) said.
It urged governments to strengthen access to services and interventions that support breastfeeding as part of World Breastfeeding Week, observed annually from August 1–7.
The 2026 theme, "Breastfeeding for a Sustainable Start in Life: Strengthen What Works," focuses on tracking progress, evaluating impact, and scaling proven approaches that improve breastfeeding outcomes.
"Scaling up breastfeeding could prevent almost 400,000 child deaths and around 140,000 maternal deaths each year," said UNICEF Executive Director Catherine Russell and WHO Director-General Dr. Tedros Adhanom Ghebreyesus in a joint statement.
"Every US$1 invested in breastfeeding promotion generates an estimated US$59 in economic returns through lower health-care costs, improved cognitive development, higher educational attainment, and increased lifetime earnings," they added.
The experts noted that breastfeeding is one of the simplest and most powerful ways to protect a child's health. It provides infants and young children with essential nutrition, boosts immunity, helps protect against serious illnesses, and supports cognitive development.
For mothers, breastfeeding also offers significant health benefits by reducing the risk of noncommunicable diseases such as breast and ovarian cancers, and type 2 diabetes.
The WHO said breastfeeding rates have improved globally due to sustained investments in policies and programs supporting mothers and families.
Exclusive breastfeeding during the first six months increased from around 37 per cent in 2012 to more than 47 per cent today. Over the past five years, the prevalence of breastfeeding up to two years of age has risen from 38 per cent to 50 per cent.
Despite these gains, the WHO said many countries continue to lag behind global targets.
"Coverage of services supporting breastfeeding remains low, policies are inconsistently enforced, and service quality is often inadequate, especially in low-income, fragile, and humanitarian settings," the WHO said.
The agency noted that cost-effective interventions include skilled breastfeeding support within health systems, community-based counselling, maternity protection policies, and protection from the exploitative marketing of commercial milk formulas.
WHO and UNICEF called on governments, health systems, workplaces, communities, civil society organizations, and families to strengthen the "Warm Chain of Support" for breastfeeding.
During World Breastfeeding Week, the agencies urged countries to:
"Breastfeeding is vital. By investing in proven solutions, we can give every child the best possible start in life and ensure every mother gets the care and services she needs," the agencies said.

A new study published in The Lancet Regional Health–Southeast Asia has found that India accounts for 68% of all childhood cancer cases in the SAARC region.
While the country's large child population contributes to the high numbers, experts say underdiagnosis and incomplete cancer registration may mean the actual burden is even greater.
An international team of researchers, including from the US, India, and Canada, estimated that nearly 37,700 children aged up to 14 years were diagnosed with cancer across South Asia in 2022, with 17,700 deaths reported. India alone accounted for an estimated 25,939 cases and 12,028 deaths.
The researchers noted that because cancer registration remains incomplete, particularly in rural areas, the true number of childhood cancer cases in India could exceed 50,000 annually.
India is home to more than 380 million children, accounting for nearly 69% of the child population in the SAARC region. This naturally contributes to the country's higher share of childhood cancer cases and deaths.
However, experts emphasize that population size is only part of the explanation. Delayed diagnosis, limited access to specialized treatment, and gaps in cancer registration continue to affect both disease estimates and patient outcomes.
Dr. Narendra Agrawal, a leading Hematologist and Bone Marrow Transplant Physician and Senior Consultant and Unit Head of Haemato-Oncology at Rajiv Gandhi Cancer Institute & Research Centre, told HealthandMe that childhood cancer remains a major public health concern in India.
"Current estimates suggest that around 70,000–80,000 children and adolescents develop cancer each year, although the exact number remains uncertain due to expanding cancer registration systems". The most common childhood cancers in India include:
Unlike many adult cancers, most childhood cancers do not have a clearly identifiable or preventable cause. Dr. Agrawal explained that, in most children, cancer develops because of genetic changes that occur during early development. These changes are usually not linked to lifestyle factors or inherited from parents.
Although the causes of most childhood cancers remain unclear, some well-established risk factors include:
Dr. Agrawal said India's substantial childhood cancer burden is largely driven by its population size. However, improving outcomes requires addressing several systemic challenges.
Key issues include:

A small spot on a lung CT scan can be alarming, with many people immediately fearing the worst. However, doctors say that a lung nodule is a common finding and, in most cases, is not cancer. On , specialists explain what lung nodules are, why they appear, which features may warrant closer evaluation, and how timely diagnosis can help detect serious conditions early and prevent unnecessary anxiety.
Dr. Gyanendra Agrawal, Senior Director - Interventional Pulmonology & Pulmonary Intensive Care, Max Super Speciality Hospital, Noida, told Health and me, "It is essential to talk about one of the most serious concerns of the patients who have undergone a CT scan on World Lung Cancer Day, oftentimes linked with the description of a spot/nodule found in the lungs. Some people see this term in the report and are gripped by fear; unfortunately, not all spots in the lung signify lung cancer."
According to Dr. Vinayak Maka, Senior Oncologist, Department of Oncology, Ramaiah Memorial Hospital, "A lung nodule is a small, round or oval-shaped growth in the lung, typically less than 3 cm in size, most often discovered incidentally during a chest X-ray or CT scan done for an unrelated reason."

Notably, nodules are extremely common; many people carry one without ever knowing it, and without it causing any symptoms. They can form due to a wide range of causes, including old infections, inflammation, scar tissue, or benign growths. In a smaller proportion of cases, a nodule may represent an early cancerous growth, which is why understanding its characteristics matters.
"A lung nodule finding on a CT scan often triggers panic, but the reality is reassuring: over 95% of lung nodules are benign, arising from old infections, scars, or inflammation. Still, understanding when a nodule warrants concern can be lifesaving." Dr. Vinayak Maka added.
Size is the key factor when assessing a lung nodule, alongside the patient's overall health. Nodules smaller than 6 mm have a very low cancer risk (under 1%) and usually only need routine follow-up. Those measuring 6–8 mm carry a slightly higher risk (1–2.5%) and are typically monitored with a repeat CT scan after 6–12 months.
On the other hand, Dr. Shyam Krishnan, Lead Consultant, Clinical & Interventional Pulmonology, CMRI (CK Birla Hospitals), Kolkata, told Health and me, "This World Lung Cancer Day, my message is simple. Do not ignore the shadow on your scan — but do not be paralysed by it either. Get it checked by people who can tell you exactly what it is. In lung cancer, a precise and early answer is the single most powerful thing we have. And that answer is now closer, gentler, and faster than most people realise."
Finding a lung nodule does not automatically mean a diagnosis of lung cancer. Experts stress that the size, appearance, and a person's medical history all play a role in determining the next steps.
