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.
From childhood, many girls are taught to be agreeable, responsible and perfect in everything they do. They are praised for being obedient, hardworking and emotionally controlled. Over time, this expectation can shape behavior in ways that may quietly harm mental and physical health.
This pattern is often referred to as “Good Girl Syndrome”. While it is not a formal medical diagnosis, doctors say the effects of constantly trying to live up to expectations can be very real. The pressure to appear composed and capable all the time can lead to emotional suppression, chronic stress and eventually hormonal disturbances.
To understand how this pressure affects the body, NDTV Health spoke with Dr. Y. D. Meherprasad, Senior Consultant in Endocrinology and Preventive Healthcare at MGM Malar Hospital, Chennai, who says he has observed this pattern among many young women in his clinical practice.
Good Girl Syndrome describes a behavioral pattern where individuals, often women, feel compelled to meet expectations without showing weakness or stress. This can translate into people pleasing behaviour, fear of conflict and difficulty setting boundaries.
Dr. Meherprasad explains that constantly trying to maintain this image can create a persistent stress response in the body.
“Hormonal imbalances are being noticed in young Indian women associated with the Good Girl Syndrome, where women are always trying to meet expectations and are continuously successful, all without showing any signs of stress,” he told NDTV Health.
According to him, the problem arises when emotions are suppressed for long periods. “When women suppress emotions for long periods, the body remains in a state of constant stress response,” he said.
Emerging research in the field of psychoneuroendocrinology suggests that emotional stress can directly influence hormonal regulation in the body.
At the centre of this process is cortisol, the body’s main stress hormone. Normally, cortisol rises briefly during stressful situations and then returns to normal levels once the threat passes.
However, when stress becomes constant, cortisol levels can remain elevated for long periods.
Studies have shown that chronic high cortisol can disrupt reproductive hormones. One effect described in research is sometimes called “progesterone steal,” where the body prioritizes producing stress hormones instead of reproductive hormones.
Low progesterone levels can contribute to irregular menstrual cycles, acne and other hormonal symptoms that many young women experience.
Dr. Meherprasad says chronic stress may also contribute to metabolic changes. In some cases, it can mimic or worsen conditions such as Polycystic Ovary Syndrome (PCOS).
When cortisol levels remain high, the body releases more glucose into the bloodstream to provide energy for a perceived threat. If that energy is not used through physical activity, insulin levels rise to regulate blood sugar.
Over time, this can lead to insulin resistance, which is a key factor associated with PCOS. Women may experience abdominal weight gain, irregular ovulation and difficulty managing their weight.
The effects of prolonged stress do not appear overnight. They often show up gradually through subtle changes in the body.
Dr. Meherprasad says menstrual irregularities are one of the early warning signs. Some women may experience delayed cycles or even a temporary halt in ovulation.
Sleep disturbances are also common. Many women report difficulty falling asleep because their minds remain constantly active, leading to fatigue the next day.
Other symptoms may include mood swings, persistent anxiety, brain fog and difficulty losing weight despite maintaining a careful diet.
Dr. Meherprasad says addressing these hormonal issues requires both medical evaluation and lifestyle changes.
Regular hormone screenings can help detect issues related to thyroid function, insulin levels and reproductive hormones such as LH and FSH. Early treatment is important if conditions such as PCOS or thyroid dysfunction are present.
Equally important is addressing the emotional component of chronic stress.
“Hormonal imbalance is not only physical but also closely linked to emotional health,” said the doctor.
He recommends prioritizing adequate sleep, regular physical activity and practices such as yoga that help calm the body’s stress response. Creating space for emotional expression through journaling or therapy can also help reduce long term stress.
In a culture that often rewards perfection, doctors say it may be time to rethink the idea of the “perfect girl”. Sometimes, protecting one’s health begins with allowing space for imperfection.
Cancer deaths in the United Kingdom have dropped to their lowest recorded levels, according to new data from the charity Cancer Research UK. The figures show that cancer death rates have fallen by 11 per cent in the past decade, reflecting progress in early detection, screening, treatment and prevention.
Researchers estimate that around 247 people in every 100,000 in the UK now die from cancer each year. This is a significant decline from the peak recorded in 1989, when about 355 people per 100,000 died annually from the disease. Overall, that represents a 29 per cent reduction over the past few decades.
Experts say this steady improvement is the result of sustained scientific progress, improved healthcare systems and public health measures that target risk factors such as smoking.
The new data highlights falling death rates across several major cancers. Ovarian cancer deaths have dropped by 19 per cent over the past ten years, up to 2024. Lung cancer deaths have fallen by 22 per cent during the same period, reflecting the long-term impact of reduced smoking rates and better treatment options.
Deaths from stomach cancer have seen one of the most dramatic improvements, dropping by 34 per cent in the past decade. Bowel cancer deaths have decreased by six per cent, while breast cancer deaths have fallen by 14 per cent.
Other cancers have also seen notable declines. Cervical and prostate cancer deaths have both dropped by 11 per cent. Deaths from leukemia are down by nine per cent, while esophageal cancer deaths have fallen by 12 per cent.
Experts say improved diagnosis, new therapies and better awareness are playing a key role in these trends.
One of the biggest public health successes has been the decline in cervical cancer deaths. Since the 1970s, deaths from cervical cancer have fallen by around 75 per cent in the UK. Health experts attribute much of this progress to the national cervical screening programme run by the NHS.
Screening helps detect abnormal cells early, allowing treatment before cancer develops or spreads.
Another major contributor is the human papillomavirus vaccine, commonly known as the HPV vaccine. The vaccine protects against the virus responsible for most cervical cancer cases. It is routinely offered to schoolchildren in the UK, and since its introduction in 2008, at least 6.5 million young people have received it.
Public health experts believe the vaccine will continue to reduce cervical cancer rates in the coming decades.
Despite the overall progress, the data also shows worrying increases in deaths from certain cancers. Gallbladder cancer deaths have risen by 29 per cent, while deaths from eye cancer have increased by 26 per cent.
Liver cancer deaths are up by 14 per cent, and kidney cancer deaths have risen by five per cent. Meanwhile, death rates for thyroid cancer, pancreatic cancer and melanoma have remained largely unchanged.
Another important trend is that the total number of people dying from cancer continues to rise. This is largely due to population growth and an ageing population, as cancer risk increases with age.
Experts say the long-term decline in cancer deaths reflects decades of medical research and innovation. However, they stress that continued investment is necessary to sustain progress.
Cancer Research UK researcher Dr Sam Godfrey said the figures show the impact of scientific breakthroughs over many years. He has called on the government to support more clinical trials and ensure that NHS staff have enough time and resources to take part in life saving research.
Public health policies such as smoking bans, along with screening programmes and vaccines, are also credited with helping drive down cancer deaths across the country.

Are you in the habit of catching up on social media or news updates while sitting on the pot? A new study shows you may be "unintentionally" spending extra time and increasing your risk of developing painful hemorrhoids by 46 percent.
The study, published in the open-access journal PLOS One, explained that getting distracted by news or social media can increase pressure on sensitive anal tissues, which leads to hemorrhoids.
Hemorrhoids, also called piles, are swollen and inflamed veins around your anus or in your lower rectum.
"Using a smartphone while on the toilet was linked to a 46 percent increased chance of having hemorrhoids. We're still uncovering the many ways smartphones and our modern way of life impact our health,” Trisha Pasricha, from the Beth Israel Deaconess Medical Center in the US.
“It's possible that how and where we use them -- such as while in the bathroom -- can have unintended consequences," she added.
For the study, the researchers examined data from colonoscopies of 125 adults in America, and conducted an online survey to understand their lifestyle habits and behavior while using the toilet.
Two-thirds of the participants reported using their smartphones while on
the toilet. Compared with those who did not, endoscopists found that they had a 46 percent higher risk of hemorrhoids.
More than a third of bathroom smartphone users reported spending more than five minutes there during a single visit -- reading news (54.3 percent), or browsing social media (44.4 percent).
In comparison, just 7.1 percent of non-users reported staying that long.
"Smartphone use may unintentionally extend the time people spend sitting on the toilet. Sitting for longer periods could increase pressure on tissues in the anal region, which may contribute to the development of hemorrhoids,” the researchers said.
Pasricha suggested individuals leave smartphones outside the bathroom to understand the actual time it takes for a bowel movement.
"If it's taking longer, ask yourself why. Was it because having a bowel movement was really so difficult, or was it because my focus was elsewhere?" she said, calling for more studies.
Studies estimate that hemorrhoidal disease affects 40% of people all over the world, and it is one of the most common diseases in the anorectal region.
The two types of hemorrhoids are:
