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.

Heart attacks are often associated with severe chest pain, but health experts warned that many cases present with unusual symptoms such as jaw pain and nausea that are frequently ignored or mistaken for less serious conditions.
Ischemic Heart Disease (IHD) or heart attacks is the leading cause of death worldwide, responsible for roughly 9 million deaths annually
Speaking to HealthandMe, the experts highlighted unusual symptoms that may indicate a heart attack — particularly in women, elderly people, and individuals with diabetes. These include:
Dr. Prasanthi Ganji, HOD - Emergency Medicine at Manipal Hospital, Gurugram, called these “referred symptoms”, where pain from the heart travels through shared nerve pathways and is felt in other parts of the body, including the jaw, neck, shoulders, or back.
The expert explained that nausea may occur because reduced blood flow and stress on the heart can affect the nervous system and digestive response.

According to her, many patients mistake these symptoms for acidity, fatigue, or muscle strain, leading to dangerous delays in treatment.
“Recognizing these warning signs during the critical golden hour can significantly improve survival and reduce long-term heart damage,” Dr. Prasanthi told HealthandMe, adding that symptoms lasting more than a few minutes should never be ignored.
Dr. Saifa M. Latheef, Associate Professor and Clinical Head – Emergency Medicine at ShardaCare-Healthcity, said public awareness about silent or unusual heart attack symptoms remains low.
“Many people believe that a heart attack always causes severe chest pain. However, this is not true in every case,” she said.
Dr. Saifa noted that some patients may experience heaviness in the jaw, vomiting sensation, breathlessness, or extreme weakness without chest pain, causing them to delay emergency care.
“A heart attack occurs when blood flow to the heart suddenly gets blocked, making immediate medical attention crucial to save heart muscle and prevent complications,” the doctor told HealthandMe.
The health experts also flagged the delaying attitude of patients, which increases the risk of poorer outcomes.
Dr. Nitin Jagasia, Regional Director Emergency, Western Region, Apollo Hospitals, said the biggest mistake patients make is waiting too long before seeking help.
“As an emergency doctor, I meet patients every day who say, ‘Doctor, I thought it would go away,’” he told HealthandMe.
Dr. Jagasia warned that heart attacks do not always begin with crushing chest pain and that unusual symptoms like nausea, sweating, stomach discomfort, or unexplained fatigue are often mistaken for acidity or stress.
“A simple rule to remember is this: if a symptom is sudden, severe, or frightening, do not wait for it to pass,” he said.

The experts emphasized that timely treatment, CPR awareness, and rapid emergency response remain the strongest defences against sudden cardiac emergencies.
They also highlighted the importance of preventive measures such as regular exercise, healthy eating, stress management, quitting smoking, and controlling diabetes and blood pressure.
Obesity is indirectly associated with stroke risk. (Photo credit: AI generated)
Obesity is a very significant modifiable risk factor for brain stroke, which is an extremely dangerous illness caused by an insufficient or lack of blood supply to the brain. Stroke leads to disability, memory impairment, paralysis, and sometimes death. As obesity is related to many illnesses, regulation of weight can considerably decrease the probability of suffering a brain stroke.
Dr Bhupesh Kumar Mansukhani, Director of Neurology at Neuromet Wellness Care & Diagnostics, in an interview with Health and Me, said, "Obesity is an excessive accumulation of fat in the body, which causes damage to health. Obesity is determined using the BMI index. Those who suffer from obesity are more prone to illnesses like hypertension, diabetes, and elevated cholesterol levels, all of which put people at a higher risk of suffering a brain stroke. Excessive fat, particularly abdominal fat, affects the arteries, leading to their constriction."
Hypertension, or high blood pressure, is yet another major connection between obesity and stroke. Obesity causes stress on the cardiovascular system and elevates blood pressure levels. Such a state poses a risk of injury to the blood vessels in the brain, causing their rupture or blockage. Obesity usually results in diabetes, and both conditions harm the walls of the blood vessels and increase the risk of blood clot formation. Besides, the increased concentration of cholesterol contributes to plaque accumulation in the arteries.
The presence of obesity in the body stimulates inflammatory reactions and reduces the rate of circulation, which may cause the formation of blood clots. As a result, these clots are delivered to the brain and prevent blood from delivering oxygen to it, and ischaemia becomes the trigger for an ischaemic stroke, which is the leading type of stroke.
The advantage here is that obesity is a modifiable risk factor, which can actually be avoided or managed. Proper nutrition, physical exercise, adequate sleep, and the absence of negative behaviours will enable an individual to maintain a healthy body weight. It is also important to take part in preventive measures, such as having regular medical examinations and testing one’s blood pressure, glucose levels, and cholesterol.
To conclude, it can be noted that obesity contributes significantly to increased risks of developing a brain stroke due to many reasons, including hypertension, diabetes mellitus, and vascular diseases. Being a modifiable risk factor, it can be easily avoided.

Cancer is, without a doubt, one of the most feared diseases known to man. According to the Indian Council of Medical Research - National Cancer Registry Programme (ICMR-NCRP), India gets 1.5 million new cases of the disease every year, with one in nine people likely to develop cancer in their lifetime. On the other hand, the American Cancer Society (ACS) and National Cancer Institute (NCI) expect about 2,114,850 new cases in the United States this year alone.
A new study claims that the weight loss drug, glucagon-like peptide-1 (GLP-1), may help slow the spread of some cancers. The research was done by the Cleveland Clinic and claimed that the medications may slow down the spread of several obesity-related cancers, including lung, breast, colorectal, and liver cancers.
The official press release by the Cleveland Clinic mentions their research being included 12,112 patients with the following types of obesity-related cancers, ranging from stage 1 to stage 3, and half of these participants started a GLP-1 medication after their cancer diagnosis. The others were taking a DPP-4 inhibitor comparator, "gliptins," a different class of diabetes medications.
The comparison between the two groups clearly shows that the patients who took GLP-1 have a much lower progression to stage 4 disease for four types of cancers.
The study author, Mark David Orland, MD, of the Taussig Cancer Institute at Cleveland Clinic, said, "Our study found that use of GLP-1 drugs, compared to DPP-4 inhibitors and other antidiabetic drugs, was associated with a meaningful reduction in cancer progression across four solid tumor types."
