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.

Chronic obstructive pulmonary disease (COPD) has long been seen as a condition of older adults, typically tied to years of smoking. But across India, pulmonologists are increasingly diagnosing it in people in their 20s and 30s. This shift, experts say, reflects a deeper and more troubling change: young adults are growing up and living in environments where the lungs never truly get a chance to breathe clean air.
The biggest change is the cause itself. As Dr. Raja Dhar, Director & HOD, Pulmonology, CK Birla Hospitals, CMRI Kolkata, explains, “COPD is increasingly becoming an ‘exposure disease’ rather than a ‘smoker’s disease.’ In India, non-smoking COPD is numerically a much larger problem.”
This exposure begins early—sometimes in childhood.
Dr. Dhar highlights how even limited exposure can have lifelong consequences: “Severe airway obstruction can be traced back to just six to seven years of biomass smoke exposure in a poorly ventilated kitchen during a child’s formative years.”
Dr. Harshil Alwani, Consultant – Pulmonology, CK Birla Hospitals, Jaipur, also points to the changing risk profile. According to him, “newer epidemiological data show that non-smoking drivers—especially air pollution and occupational exposures—are playing a disproportionately large role in younger people.” He adds that rapid urbanisation means more young adults are chronically breathing polluted air from childhood onwards.
Improved diagnosis and greater awareness also mean younger patients with persistent symptoms are now being evaluated more often, he notes.
Both experts agree that polluted air is the biggest trigger today. Dr. Alwani explains that long-term exposure to PM₂.₅ is directly linked to lung decline and COPD. “Recent research shows that temperature and humidity modulate the harmful effect of PM₂.₅, making COPD risk worse under certain climatic conditions,” he says.
Dr. Dhar adds that India’s air quality is deteriorating nationwide: “Ambient outdoor air pollution is a severe risk, as air quality across 98% of India is worse than WHO standards.”
Household pollution remains a massive issue. Biomass fuel used for cooking is, as Dr. Dhar puts it, “the largest non-smoking contributor, resulting in numbers approximately three times that of smoking-related COPD.”
Young adults working in construction, mining, welding, or factory settings face daily exposure to dust, fumes, and chemicals. Dr. Alwani notes that such environments “carry a significantly increased risk.”
Recurrent infections can impair lung development and reduce lung reserve, making early-onset disease more likely.
Conditions like alpha-1 antitrypsin deficiency, though rare, still contribute when combined with environmental triggers.
Every winter, Delhi’s smog becomes a health emergency. According to Dr. Dhar, “High winter pollution, particularly hazardous levels of PM2.5, acts as a chronic, low-grade chemical burn on the young respiratory system.”
Dr. Alwani adds that winter inversion traps pollutants closer to the ground, amplifying PM₂.₅’s damage.
Vaping and e-cigarettes, widely perceived as harmless, have added a new layer of risk. Dr. Alwani warns, “Vaping is not benign. Its aerosols contain volatile compounds, heavy metals, and ultrafine particles that trigger inflammation and oxidative stress—central pathways to COPD.”
Dr. Dhar echoes this concern: “Any inhalation of heated chemical aerosols is a significant lung irritant and pro-inflammatory agent.”
Doctors urge young adults not to dismiss symptoms like:
Early spirometry can dramatically change outcomes. As Dr. Dhar puts it, “Early intervention allows us to remove the source of exposure and start therapy, which can effectively preserve the patient’s remaining lung function.”
Dr. Alwani adds that catching the disease early can “significantly slow further lung damage” and prevent long-term complications.

On International Men's Day, we shift our focus on men's health and why is it important to talk about it. Time and again experts, doctors, and studies have shared how men generally visit GPs less than women. As per the NIH, US, the consultation rate is 32% lower in men than women. The difference is often attributed to a combination of women being more willing to admit sickness and seek help, while cultural factors and barriers for men keep them away from seeking help. However, not anymore, because both sexes require help when they need, especially when it is about their health.

As per a 2024 study published in the Journal of Clinical Investigation, about 5.7 million men could be living with an autoimmune disease that they do not even know about. The disease in men are often overlooked, all thanks to the social barriers.
Sex chromosomes play a key role in predisposing men or women to an autoimmune disease. Females have XX chromosomes, while male have XY chromosome and each chromosome carries gene sequence, which means specific pieces of DNA. Since X chromosome carries a bunch of gene related immunity,, having two of them could explain why women often have a higher rate of autoimmune diseases.
However, men are less likely to book time with their doctors, which could impact the discrepancies between sexes. They could thus often be undiagnosed or could flag their symptoms only when the disease has progressed.
This is an inflammatory skin condition which affects both men and women. However, studies including the one published in 2023 in the International Journal of Women's Dermatology have suggested that men could develop this condition near their genitals and butt than women.

As happens due to the inflammation of the spine's joints and ligaments and could cause back pain and stiffness. While the condition is rare in itself, it could affect men more than women, that too at a younger age, usually below 40. A South Korean study from 2018, published in Scientific Reports, AS was 3.6 times more prevalent in men than women.
The 2018 report by the Centers for Disease Control and Prevention, (CDC), US, provides data that type 1 diabetes may be slightly more in common in men than women. Though, other studies have been a mixed bag. Unlike type 2 diabetes, type 1 is an autoimmune disease, which means, here immune system attacks are specialized. What men should know is that both types of diabetes could up their risk of erectile dysfunction (ED) due to persistently high blood sugar, which could harm their nerves and blood vessels.
A 2016 study published in the International Journal of Impotence Research found that nearly 60% of 151 men being treated for type 1 diabetes had mild ED.
The most common forms are Crohn's disease and ulcerative colitis, that take hold of digestive system. Chronic inflammation in the gut spikes the risk of colorectal cancer, which is one of the leading cause of death in men between 20 to 49 of ages. In fact, a 2023 study published in the journal Cancers noted that men with IBD faced a higher risk of developing colorectal cancer than women with IBD.

Not every medicine carries the same level of risk. Some drugs can trigger reactions that are severe or even life-threatening. When that possibility exists, the manufacturer is required to place a special notice inside the prescribing information. This highlighted section is known as a black box warning.
A black box warning is meant to draw clear attention to the most serious dangers linked to a drug. Many medicines fall under this category. Still, having the warning in place does not automatically make the treatment unsafe. When a drug is used correctly and monitored by a trained professional, the benefits may outweigh the risks.
The sections below outline what an FDA black box warning means, why a medicine might receive one, and how it may influence your treatment plan.
A black box warning is the strongest caution that the FDA can attach to a prescription drug. You might also see it described as a boxed warning.
The presence of this warning does not mean a person should never take the medication. Instead, it alerts doctors and patients to serious potential harm. This information helps clinicians decide who is an appropriate candidate and under what circumstances the drug should be used.
Many medicines with boxed warnings remain the best or only option for certain conditions.
A drug receives this type of label when it has been linked to outcomes such as permanent injury, hospitalisation, or death. These warnings should be read carefully, and patients should discuss them openly with their healthcare provider.
Doctors follow specific precautions when prescribing drugs that carry this label to minimize unnecessary risk.
The warning sits at the very top of the medication’s official package insert. Its placement is deliberate so it stands out immediately. The text is printed inside a bold black border, which is how the term “black box” took hold.
You may not always receive the full package insert from the pharmacy. However, you might receive a medication guide if the drug is considered high-risk. These guides describe proper use and highlight major side effects. You can also look up medication guides online.
Information about boxed warnings is available from multiple sources. The FDA website, the drug manufacturer’s website, and medical reference sites used by clinicians all include these details.
Every prescription drug must go through extensive testing before it reaches the market. During this process, researchers aim to uncover risks that could require a boxed warning from the start. Even so, some side effects only appear once large numbers of people begin using the drug in everyday settings.
Because of this, most black box warnings are added after a medicine has already been approved. The FDA continues to monitor safety reports through MedWatch, a program where patients, physicians, and companies can report problems.
These reports are gathered in a database called the FDA Adverse Event Reporting System. When the agency notices a pattern of serious reactions, they investigate. If needed, they update the prescribing information and add a boxed warning so that future users are clearly informed.
