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.

The Gut-Brain Axis: How Diet May Influence Parkinson’s Disease

Updated Apr 11, 2026 | 02:00 PM IST

SummaryGut-targeted interventions are promising adjuncts to conventional Parkinson's therapy, improving patients' quality of life. Changes in the gut microbiome may influence inflammation, α-synuclein aggregation, and symptom progression.

Parkinson’s Disease is traditionally characterized by motor symptoms such as tremor and dyskinesia, although non-motor symptoms, in particular gastrointestinal (GI) symptoms such as constipation and incomplete emptying, are often the first markers of the disease and may precede the motor symptoms by years.

GI dysfunction is reported in approximately 70-80 per cent of Parkinson’s patients, mediated in large part through the gut-brain axis (GBA).

Speaking to HealthandMe, Dr Paresh Doshi, Director of Neurosurgery and Stereotactic and Functional Neurosurgery at Jaslok Hospital and Research Center, GBA, is an established two-way network that links the GI tract and the central nervous system (CNS). The connection is multifaceted, involving the vagus nerve, the enteric nervous system (ENS), the immune system, and a vast number of microbial metabolites and neuroendocrine signals.

“Constipation is seen in 66 per cent of Parkinson’s patients, attributed to disordered central and peripheral parasympathetic disruption, and can lead to alteration of the gut microbiome, which in turn worsens constipation, starting a feedback loop,” the doctor explained.

What Parkinson’s Patients Must Eat

Dr Sudhir Kumar, Neurologist at Apollo Hospitals Hyderabad, told HealthandMe that changes in the gut microbiome may influence inflammation, α-synuclein aggregation, and symptom progression.

Practical dietary principles for Parkinson’s patients include:

  • Prefer fiber-rich, plant-based foods (vegetables, fruits, whole grains), which support gut microbiota
  • Include fermented foods (curd, buttermilk), which may improve microbial diversity
  • Reduce ultra-processed and pro-inflammatory foods
  • Ensure adequate hydration (helps reduce the risk of constipation, a common non-motor symptom)
  • Protein timing matters: Levodopa competes with amino acids for absorption.
Hence, lowering protein intake at breakfast and lunch and shifting the bulk of protein to dinner can improve drug response in selected patients with motor fluctuations.

These gut-targeted interventions are promising adjuncts to conventional Parkinson's therapy, and improving patient quality of life.

Parkinson’s Treatment With Dance, Art

Beyond gut-brain axis, research has proven that unconventional therapy, like dance and art, can improve Parkinson’s treatment.

A 2024 study published in the Scientific Reports found that tango, particularly Argentine tango, improved Parkinson's symptoms like thinking problems or balance issues. It also led to a significant improvement in recognizing emotions on people's faces.

Dr Kumar said dance therapy improves balance, gait, and coordination; provides rhythmic cueing, which enhances motor performance, and improves mood and motivation (dopamine-related pathways).

Similarly, art therapy has been shown to improve overall visual-cognitive skills and visual exploration strategies as well as general motor function in patients with Parkinson’s. The changes in brain connectivity highlight a functional reorganization of visual networks, as revealed by a study published in Parkinsonism & Related Disorders.

Dr Kumar said art and creative therapies are also helpful in enhancing cognitive engagement. It may help with executive function and emotional well-being and provide a non-verbal outlet for expression. However, these therapies work best as adjuncts, not replacements, to standard treatment, the expert noted.

World Parkinson’s Day 2026

World Parkinson's Day is observed annually on April 11 to raise global awareness of Parkinson’s disease, the world's fastest-growing neurodegenerative disorder.

It highlights the need for early diagnosis, research, and support for the nearly 10 million people living with the condition. The day marks the birthday of Dr. James Parkinson, who first described the disease in 1817.

The theme of World Parkinson's Day 2026 is "Bridge the Care Gap." It reflects a critical challenge that persists despite advances in medical research: many people living with Parkinson's still lack consistent access to specialist care, affordable treatment, and integrated support systems.

Parkinson's disease affected 11.9 million people in 2021 and will affect 25.2 million people globally by 2050, representing an alarming 112 per cent rise.

Why Early-Onset Parkinson’s Can Be Missed In Young Working Professionals?

Updated Apr 11, 2026 | 01:48 PM IST

SummaryIn younger individuals, Parkinson’s Disease often develops slowly and remains mild in the beginning, which makes it harder to recognize. The exact cause may involve a mix of genetic factors and environmental triggers.

For most working professionals, Parkinson’s disease still feels like something that happens much later in life. It’s not something people in their 30s or even early 40s actively think about. But this scenario is changed with early onset Parkinson’s disease (EOPD). This can affect people between the ages of 21 and 50.

The problem is not just the condition itself, but how it subtly integrates into everyday life. Despite this shift, early symptoms in working professionals often go unnoticed or are misattributed to stress, fatigue, or demanding work schedules.

What Is Early-Onset Parkinson’s Disease?

Parkinson’s disease is a neurological condition that affects movement and coordination due to a reduction in dopamine-producing cells in the brain. When it occurs between the ages of 21 and 50, it is referred to as early-onset Parkinson’s disease (EOPD). In younger individuals, the condition often develops slowly and remains mild in the beginning, which makes it harder to recognize. The exact cause may involve a mix of genetic factors and environmental triggers.

Symptoms can include both movement and non-movement changes. Movement-related symptoms may involve muscle stiffness, slowed movements, mild balance issues, tremors at rest, while non-movement symptoms such as constipation, unexplained pain, sexual dysfunction, and sleep disturbances like insomnia may appear early.

In day-to-day life, these changes often show up subtly as slight hand shaking at rest, taking longer to complete routine tasks, stiffness in the neck or shoulders, a softer or less expressive voice, and disturbed sleep patterns, signs that are easy to overlook or dismiss.

What are the symptoms that working professionals may miss?

1. Symptoms Overlap With Lifestyle Issues: In fast-paced work environments, fatigue, body aches, and sleep disturbances are common. Early Parkinson’s symptoms, such as stiffness, low energy, or poor sleep, are often dismissed as burnout or long working hours.

2. Lack of Awareness in Younger Age Groups: Both patients and even healthcare providers may not immediately suspect Parkinson’s in someone in their 30s or 40s. This leads to delays in seeking medical advice and diagnosis.

3. Absence of Classic Tremors Initially: Tremors are widely recognized as a hallmark of Parkinson’s, but they may not appear in the early stages. Instead, symptoms like reduced arm swing while walking or slight slowness in movements may be present but overlooked.

4. Attribution to Mental Health or Stress: Subtle changes such as anxiety, low mood, or difficulty concentrating can be early indicators. However, these are often attributed to workplace stress rather than a neurological cause.

5. Gradual Onset of Symptoms: Parkinson’s develops slowly. Changes in handwriting, posture, or speech may happen over time, making them difficult to notice unless specifically looked for.

How Can Parkinson’s Be Diagnosed and Managed?

Because early signs are often overlooked, the condition is often recognized only when it begins to affect daily life. Diagnosis typically involves a detailed assessment along with blood tests and imaging, such as MRI, and in some cases, specialized scans like a dopamine transporter (DAT) scan may also be advised to support the diagnosis.

Management focuses on improving quality of life through physical therapy to support movement and balance, occupational therapy to make daily activities easier, and speech therapy to address communication changes. In more severe cases, deep brain stimulation (DBS) surgery may be considered to help manage symptoms more effectively.

Parkinson’s at a younger age is often easy to overlook, especially when early signs blend into everyday stress and fatigue. Paying closer attention to overall well-being can help. Staying physically active, following a balanced diet, maintaining good sleep habits, and managing stress levels all play an important role in supporting brain health. Being mindful of small but persistent changes and not brushing them off as routine can go a long way in ensuring timely attention and better long-term.

World Parkinson’s Day is observed every year on April 11 to raise awareness about the progressive, neurodegenerative movement disorder caused by the loss of dopamine-producing brain cells.

People suffering from Parkinson’s face problems in motor movement, tremors, stiffness, and impaired balance. As symptoms progress, people may have difficulty walking, talking, or completing other simple tasks.

The condition primarily affects people over 60, but is now increasingly being seen in young adults. Apart from motor loss, the disease also causes cognitive decline, depression, anxiety, and swallowing problems.

World Parkinson's Day 2026: Origin

Parkinson's Day is observed on the day that marks the birthday of James Parkinson (born in 1755). The London-based doctor was the first to describe Parkinson as a medical condition in 1817, in his famous ‘Essay on the Shaking Palsy’. In 1997, the day was officially established by the European Parkinson’s Disease Association.

World Parkinson's Day 2026: Theme

The theme of World Parkinson's Day 2026 is "Bridge the Care Gap." It reflects a critical challenge that persists despite advances in medical research: many people living with Parkinson's still lack consistent access to specialist care, affordable treatment, and integrated support systems.

The day also aims to raise awareness about neurodegenerative diseases by educating the public about Parkinson's symptoms, causes, and available care.

Global Burden of Parkinson’s

Parkinson's disease affected 11.9 million people in 2021 and will affect 25.2 million people globally by 2050, representing an alarming 112 per cent rise.

According to a 2025 study released by The BMJ, this rise is mainly due to population aging and hence ranks as one of the most rapidly growing neurological disorders based on prevalence and disability. This alarming increase necessitates immediate global health interventions, research innovation, and policy reform to counteract its effects on people and health systems globally.

In addition, lifestyle differences, genetic susceptibility, and environmental exposures can also lead to regional variation in prevalence.

What Happens To Your Brain In Parkinson's Disease?

Parkinson's Disease affects various brain regions, but the primary symptoms arise from the degeneration of neurons in the substantia nigra, a region near the brain's base. This area is crucial for producing dopamine, a chemical messenger essential for smooth and purposeful movement. Research indicates that by the time Parkinson's symptoms become evident, patients have typically lost 60 to 80% or more of these dopamine-producing neurons.

Additionally, individuals with Parkinson’s disease experience a reduction in nerve endings that produce norepinephrine, a neurotransmitter responsible for regulating many involuntary bodily functions, such as heart rate and blood pressure. This loss may account for some non-movement-related symptoms of Parkinson’s, such as fatigue and fluctuations in blood pressure.

How to Prevent Parkinson's

Though there is no cure for Parkinson's disease yet, studies indicate that some lifestyle elements have the potential to shape its incidence and progression.

  • Physical Activity – Engaging in regular exercise has been linked to a reduced risk of Parkinson’s, potentially due to its neuroprotective effects.
  • Diet and Nutrition – A balanced diet rich in antioxidants, omega-3 fatty acids, and plant-based nutrients may support brain health.
  • Environmental Factors – Exposure to pesticides, heavy metals, and air pollution has been associated with an increased risk, suggesting a need for improved public health measures.
