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.

If you believe having a healthy body mass index (BMI) means you have a low risk of heart disease, you may be wrong. A new study suggests that abdominal fat may predict cardiovascular disease risk better than BMI alone.
The study, published in the Journal of the American College of Cardiology (JACC), found that failing to account for waist circumference (WC) or waist-to-hip ratio (WHR) may lead to misclassification of cardiovascular disease risk.
“Indeed, it appears that WC and WHR reclassify risk defined by traditional BMI thresholds,” said Michael J. Blaha, director of clinical research at the Johns Hopkins Ciccarone Center for the Prevention of Cardiovascular Disease.
“We saw individuals with clinically determined normal weight who had elevated central adiposity and high WHR, associating them with higher risk across most outcomes,” Blaha added.
BMI is calculated by dividing weight in kilograms by height in meters squared and is commonly used to diagnose overweight and obesity. However, BMI does not show where body fat is distributed.
The study examined whether adding WC and WHR to BMI could better predict future cardiovascular risk. Researchers looked at more than 260,000 people over an average of 20 years. They found that central adiposity could identify cardiovascular risk that BMI alone may miss.
Among people classified as having normal weight by BMI:
People with normal weight or overweight who had clinically defined high WC or WHR had a 15%–50% greater risk for most heart problems.
People with obesity and low WC did not have a significantly different risk of outcomes compared with those who had normal weight and low WC, except for all-cause mortality, for which their risk was significantly lower.
“Our findings emphasize the critical role of identifying elevated central adiposity, even in individuals with a normal BMI or with a BMI in the overweight range. Relying solely on BMI may result in misclassification of cardiovascular risk across a wide range of cardiovascular outcomes,” said Zeina A. Dardari, lead author of the study.
“We encourage clinicians to consider central adiposity distribution across the entire BMI spectrum when evaluating cardiovascular risk in primary prevention settings,” she added.
The researchers did not have information on several factors that can influence cardiovascular disease risk, including:
The study also included only one assessment of waist circumference and waist-to-hip ratio. This limited the researchers' ability to understand how changes in abdominal fat accumulation over time may influence cardiovascular disease risk.

Organ donation is one of the most profound ways in which we can give the gift of life to another person. To raise awareness about organ donation, it is important address common myths and encourage more people to consider pledging their organs.
India has a large number of patients waiting for organ transplants, including transplants of the liver, kidney, heart, pancreas, intestine and other organs and tissues.
Despite the significant need, organ donation rates remain low, with lack of awareness and several misconceptions continuing to be major barriers. One organ donor can potentially save multiple lives. However, for this to happen, it is important that people understand the process and make an informed decision about organ donation during their lifetime.
For most organs, donation after brain death is possible when the brain has permanently stopped functioning, but the heart is still beating, which generally occurs in an intensive care setting. Corneas can also be donated after death within a limited time period. This is why pledging your organs during your lifetime and discussing your decision with your family is important.
Organ retrieval is performed by trained medical specialists in an operating theatre. The surgical incision is carefully closed after the procedure, and the body is not mutilated.

A healthy person who is found suitable for living kidney donation through the required medical evaluation can generally continue their normal life after donation. The remaining kidney is capable of maintaining normal kidney function.
Kidney donation does not mean that a healthy donor has to take lifelong medication simply because they have donated a kidney. Some pain medication may be required during the initial recovery period, while the remaining healthy kidney continues to perform its function.
According to the source material, kidney donors do not generally need specific dietary restrictions solely because they have donated a kidney, as the remaining kidney continues to maintain normal kidney function.
Both men and women who donate a kidney can have children. For women, the source recommends waiting one year after donation before becoming pregnant to allow the body to recover completely.
Age alone does not determine whether someone can donate. The health of the donor and the condition of the organs are important considerations, and suitability is determined through medical evaluation.

• Consider pledging your organs during your lifetime and communicate your decision clearly to your family.
• Talk to your family, friends and colleagues about organ donation and help dispel common myths.
• Encourage community organisations to participate in creating awareness around organ donation.
• Do not assume that you are medically unfit to donate. A team of medical experts evaluates the donor and determines suitability.
• Organ donation is a completely voluntary decision. No individual should be pressured into donating an organ.
• Patients waiting for an organ transplant should approach a licensed transplant hospital and complete the necessary registration formalities, including through the NOTTO system.
Organ donation is ultimately about giving someone another chance at life. We should not take our organs with us; they can be used to save lives and give hope to those waiting for a transplant.

Anemia remains one of the least talked about threats to a safe pregnancy in India. The National Family Health Survey-5 data shows that 52.2% of pregnant women in India were anemic. This translates to at least one in two expectant mothers entering pregnancy with insufficient hemoglobin to meet her own and her baby’s needs.
Pregnant women with iron-deficiency anemia may feel unusually tired, weak or short of breath. Some women may suffer from dizziness, headaches, palpitations or reduced ability to concentrate. However, symptoms can be subtle and this is why routine antenatal screening is important even if the woman feels well.
Left unaddressed, it raises the risk of preterm birth, low birth weight, postpartum haemorrhage, and maternal fatigue severe enough to affect daily functioning and recovery after delivery.
Severe anaemia can also reduce a woman's ability to tolerate blood loss during delivery, making even an otherwise uncomplicated birth potentially more challenging.
Why pregnancy makes it worse? Well, blood volume expands by nearly 50% during pregnancy, and the growing fetus draws heavily on maternal iron stores, especially in the second and third trimesters. Most Indian women begin pregnancy with iron stores already depleted by poor dietary intake, frequent pregnancies, or heavy menstrual blood loss. So, the added demand tips many into overt anaemia.
1. Start Antenatal Care early. You should get a baseline haemoglobin test at your first antenatal visit, and repeat this each trimester or more if needed.
2. Iron and folic acid tablets must be taken in accordance with the prescription given. It is best to start with them before conceiving or as soon as possible in the pregnancy process, preferably in discussion. The dietary consumption may not always be sufficient to cater to the increased demands during pregnancy.
3. Pair iron-rich foods with vitamin C. A squeeze of lemon with dal or leafy greens meaningfully improves absorption. Indian gooseberry (amla), guava, oranges and tomatoes improve absorption of non-heme iron from plant based foods.
4. Include iron-dense foods regularly like leafy greens, jaggery, dates, legumes, eggs. If non-vegetarian, eat lean meat or fish, meat or poultry.
5. Treat underlying causes. Get heavy periods, worm infestations or unexplained fatigue evaluated before conception if possible.
6. Ask about your ferritin level, not just haemoglobin, since ferritin reveals depleted iron stores earlier.
Anaemia is not always caused by iron deficiency. B12 or folic acid deficiency, problems with haemoglobin production, infections, and many other medical conditions can also be contributing factors.

1. Do not stop iron supplements simply because you feel better. Treatment usually needs to continue for the recommended period to replenish iron stores.
2. Don't take iron tablets with tea, coffee or milk. These block absorption. Space them at least an hour apart.
3. Do not skip supplements because of nausea or constipation. Ask your doctor for alternate formulations instead of foregoing the supplements.
4. Don't assume fatigue is ‘normal pregnancy tiredness’ without a haemoglobin check. Persistent breathlessness, dizziness or a racing heart need evaluation.
5. Don't self-medicate with over-the-counter iron doses. Both too little and too much iron can cause harm.
6. Don't ignore mild anaemia on the assumption that it will ‘sort itself out’. It typically worsens as pregnancy progresses and has to be actively treated.
Anemia in women is mostly preventable and treatable early. Regular antenatal check ups, proper supplementation, balanced diet and timely treatment can go a long way in reducing its impact on the mother and baby. The key message is simple, really. Screen early, do not wait for symptoms, treat appropriately and maintain adequate iron stores throughout pregnancy.
