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.

Is Lemon Water Really Helpful for Preventing Kidney Stones?

Updated Oct 26, 2026 | 07:00 AM IST

SummaryLemon water may help reduce the risk of certain kidney stones by increasing citrate levels in urine, which can inhibit stone formation. However, its benefits depend on stone type and risk factors. Adequate hydration and medical guidance remain essential.

Lemon water may help reduce the risk of certain types of kidney stones, particularly calcium oxalate stones, but it is not a guaranteed preventive remedy. Lemons contain citrate, a naturally occurring substance that can bind with calcium in urine and help inhibit the formation and growth of some kidney stones.

Drinking lemon water can also support prevention by encouraging greater fluid intake. Adequate hydration increases urine volume, diluting substances such as calcium and oxalate that can crystallise and form stones. However, the benefit depends on the amount consumed, individual urinary chemistry and the type of stone a person is prone to developing.

What Are the Symptoms of Kidney Stones?

Common symptoms of kidney stones include severe pain in the back or flanks that may radiate to the groin, pain while urinating, blood in the urine, nausea and vomiting. Some small stones may pass without causing noticeable symptoms, while larger stones can obstruct the urinary tract and cause significant pain.

If kidney stone symptoms occur alongside fever, chills or difficulty passing urine, seek urgent medical attention. These symptoms may indicate an obstruction or infection that requires prompt treatment. A healthcare professional may recommend urine tests, blood tests or imaging to determine the stone's size and location.

How Much Lemon Water Should You Drink?

It is important to understand that lemon water is not a substitute for medical treatment or personalised dietary advice. Adding lemon to water without excessive sugar and salt is a practical option, but commercially prepared lemon drinks may contain added sugar, which is best limited. Lemon water may also aggravate acidity or heartburn in some individuals.

There is no universally established amount of lemon water that guarantees kidney stone prevention. The priority is to drink enough fluids to maintain adequate urine output, with individual requirements varying according to climate, physical activity and medical conditions. People who have been advised to restrict fluids because of kidney or heart conditions should follow their healthcare professional's recommendations rather than increasing their intake independently.

Who Should Take Extra Precautions?

People with a history of recurrent kidney stones should consult a healthcare professional to identify the stone type and understand their specific risk factors. Depending on the findings, they may need tailored fluid intake, dietary modifications or medication. A 24-hour urine test may also help identify substances that contribute to stone formation and guide preventive measures.

Adequate water intake remains the cornerstone of kidney stone prevention, while lemon water can be a useful addition to a balanced hydration routine. However, its effectiveness varies from person to person, and those at high risk of recurrence may need more targeted preventive strategies.

Woman’s Bleeding & Abdominal Swelling Linked To Rare Cancer After Being Mistaken For Perimenopause: What Is FATWO

Updated Oct 26, 2026 | 01:00 AM IST

SummaryAn Irish woman's unexplained bleeding, abdominal pain and swelling turned out to be a rare cancer called female adnexal tumour of probable Wolffian origin, commonly known as FATWO.
Woman’s Bleeding & Abdominal Swelling Linked To Rare Cancer After Being Mistaken For Perimenopause: What Is FATWO

A 43-year-old mother from Northern Ireland got diagnosed with an exceptionally rare cancer after months of pain, continual bleeding and abdominal swelling. She said that these symptoms were initially and inaccurately attributed to perimenopause, anxiety and constipation.

Nicola Crymble’s symptoms started in 2024 after she had a copper intrauterine device (IUD) inserted. The bleeding and pain became so severe that she had the device removed while she was in Kenya doing mission work. “I was constantly bleeding, there was so much pain,” Crymble said.

However, her symptoms persisted even after she returned home. She said doctors initially suggested that perimenopause and anxiety could explain what she was experiencing.

By December 2024, Crymble had noticed a lump in her abdomen. It continued to grow, making everyday activities challenging. She said people even thought she was pregnant because of the swelling. She eventually went to hospital and underwent scans, which revealed a mass near her cervix. Doctors initially thought it might be a cyst.

Crymble Got Diagnosed With FATWO, A Rare Cancer

Crymble underwent major surgery in February 2025 to remove the tumour. She also chose to have her ovaries and fallopian tubes removed during the procedure. A month later, she received the diagnosis that she had female adnexal tumour of probable Wolffian origin, commonly known as FATWO.

The tumour is believed to develop from remnants of the Wolffian duct, an embryonic structure involved in the development of the reproductive and urinary systems. Although these structures usually regress during female development, residual tissue can sometimes pave the way for tumour growth.

FATWO is an exceptionally rare form of cancer. There are only around 150 documented cases recorded worldwide. While many FATWO tumours do not metastatize, some can behave aggressively. In Crymble’s case, the cancer later spread to her liver and vaginal vault, the upper part of the vaginal canal.

She experienced intense pain beneath her ribs before a scan revealed that the cancer had spread. Further surgery was ruled out because the tumour growths were too close to other organs.

Chemotherapy As Surgery Was Not An Option

With surgery no longer an option, Crymble and her doctors decided to proceed with chemotherapy. She began treatment on October 13, 2026, and is expected to undergo six rounds, one every three weeks.

The family is also looking for specialist advice because there is limited information available about the rare disease and the best way to treat it. Her husband, Andrew Crymble, said doctors had little experience with the condition.

“They've never seen it before, they don't know how to treat it,” he said, explaining why the family decided to share her story publicly. They hope it will reach researchers or doctors who may have more information about FATWO.

Crymble has stopped working and has found it difficult to maintain her usual family routines while undergoing treatment. The family is also seeking financial support after discovering that their life insurance coverage will not cover the treatment.

Symptoms That Warrant Immediate Attention

Perimenopause can cause changes in menstrual patterns, like irregular periods. But unexplained bleeding, stubborn abdominal pain, lump or unusual swelling should not automatically be attributed to hormonal changes without seeking medical intervention.

These symptoms can occur due to many causes, and they do not necessarily indicate cancer. But worsening or unusual symptoms demand medical assessment, especially when they do not improve or when new symptoms develop.

Heatwaves, Noise & Air Pollution Can Harm Mental Health Too: New Global Commission Warns

The effects of heatwaves, air pollution, noise and overall climate change may extend beyond physical health. According to a new report by the Earth–Brain–Health Commission published in Nature Mental Health recently, they can have a significant impact on mood, cognitive function and overall psychological wellbeing.

The commission warns that environmental changes are altering the conditions in which people live. It also talks about consequences for brain health and mental wellbeing. It also calls for mental health to become a consideration in climate policy, urban planning and environmental decision making, rather than being treated only after symptoms develop.

The findings are relevant to low and middle-income countries, where exposure to environmental hazards can overlap with greater socioeconomic problems like poverty and limited access to healthcare.

“Heat and heatwaves, air and noise pollution, extreme weather and compound events, urbanization, and the loss of green and blue spaces are associated with depression, anxiety, cognitive decline, and impaired emotional and behavioral functioning,” the commission states.

Effects Of Environmental Conditions On Brain

From biological changes like neuroinflammation, disruption of hormones and the body's internal clock to psychological stress and due to isolation and displacement, the commission identifies several ways through which environmental conditions may impact mental health.

Heat exposure is one of the gravest concerns in current times. Heatwaves can disrupt sleep and contribute to physiological stress, while air pollution can lead to cognitive decline. Noise pollution and stressful urban environments may fuel anxiety and depression.

These exposures are compounded by people’s standard of living. A person living in poorly ventilated housing, for example, may face heat, air pollution, financial hardship and limited access to healthcare at the same time. These combined problems can be difficult to measure by studying each exposure separately.

Who Is At Risk?

Children, older adults, people with disabilities and marginalised communities may face greater exposure to environmental hazards while having fewer resources and help to cope with them.

The commission also highlights low and middle-income countries and small island developing states. These populations may face significant environmental risks but remain underrepresented in research on climate change and mental health.

Dr Vivek Benegal, senior professor of psychiatry and former head of department at the National Institute of Mental Health and Neuro Sciences (NIMHANS), Bengaluru, is among the commission's members. He said NIMHANS has been examining how climate change affects the human brain.

Benegal also pointed to a 2023 study conducted by researchers from NIMHANS and King's College London. The study found that even low levels of arsenic exposure, below World Health Organization thresholds, were associated with changes in brain structure and impaired cognitive abilities among children, adolescents and young adults.

Commission's Recommendations

The report recommends that governments should incorporate brain and mental health measures into environmental policies. Its recommendations include monitoring environmental exposures, identifying risks early in life, and designing healthier urban environments.

“The principal obstacles to action are organisational and financial rather than evidential,” the commission observes, noting that research cohorts, Earth-observation systems and environmental governance tools already exist but are often maintained separately.
