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.

Eli Lilly's experimental weight-loss drug retatrutide, being referred to as ‘Godzilla’, continues to outperform its rivals like Ozempic.

According to a recent head-to-head Phase 3 clinical trial involving adults with type 2 diabetes, it delivered more than twice the average weight loss achieved with Ozempic.

Ozempic Vs Retatrutide

Participants who took the highest dose of retatrutide lost an average of 20.9% of their body weight over 80 weeks, compared to 9.4% among those receiving Ozempic's highest approved dose for type 2 diabetes.

The trial, called TRANSCEND-T2D-2, involved more than 1,000 adults with type 2 diabetes. It compared once-weekly injections of retatrutide at doses of 9 mg and 12 mg with semaglutide, the active ingredient in Ozempic, at 2 mg.

At the end of 80 weeks, participants taking retatrutide 9 mg lost an average of 44.3 pounds (20.1 kg), while those receiving the 12 mg dose lost 47.4 pounds (21.5 kg). The Ozempic group lost an average of 20.9 pounds (9.5 kg).

The findings mark the first Phase 3 head-to-head comparison of retatrutide with another medicine in this class.

Retatrutide Also Improved Blood Sugar

The trial found that retatrutide also resulted in produced greater reductions in HbA1c, a measure of average blood glucose over approximately three months.

At 80 weeks, participants taking either dose of retatrutide recorded an average HbA1c reduction of 2.2%, compared to 1.8 % among those receiving Ozempic.

The experimental drug also resulted in greater improvements in cardiovascular risk factors like non-HDL cholesterol, triglycerides and systolic blood pressure.

Side Effects Of Retatrutide

The most commonly reported side effects of retatrutide were gastrointestinal symptoms like diarrhoea, nausea, constipation, vomiting and indigestion.

Diarrhoea was reported in 28.3% of participants receiving the 9 mg dose and 32.7% receiving 12 mg, compared to 26.4% in the Ozempic group. Nausea occurred in 21.2%, 23.8% and 21.3% of participants, respectively.

Researchers also reported a higher incidence of dysesthesia, an abnormal sensation that can include tingling, burning or skin sensitivity, among participants taking retatrutide.

Treatment discontinuation because of side effects occurred in 4.8% of the 9 mg group and 7.9% of the 12 mg group, compared to 2.7% of the Ozempic group.

More About Retatrutide

Retatrutide is a once-weekly injectable drug that targets three hormone receptors involved in regulating appetite, blood sugar and metabolism. They are GLP-1, GIP and glucagon.

GLP-1 helps regulate appetite and blood sugar while slowing the process of stomach emptying. GIP also plays a role in glucose regulation and insulin release. Glucagon is involved in controlling blood glucose and energy metabolism.

Ozempic, manufactured by Novo Nordisk, acts on the GLP-1 receptor. Eli Lilly's Mounjaro and Zepbound, which contain tirzepatide, target both GLP-1 and GIP receptors.

Retatrutide remains an investigational drug and has not been approved by the US Food and Drug Administration (FDA) or other regulatory authorities.

Eli Lilly plans to submit the drug for FDA approval in early 2027. The company said detailed results from the trial would be presented at a future medical meeting and published in a peer-reviewed journal.

Could GLP-1 Drugs Help Prevent Rupture Of Abdominal Aortic Aneurysm? Study Finds 46% Reduction In Risk

Updated Nov 1, 2026 | 06:00 PM IST

SummaryA recent study in the Journal of Vascular Surgery found that aortic aneurysm rupture was recorded in about 1.6% of people taking GLP-1 drugs, compared to 2.4% of those who were not taking them.

The hype around GLP-1 weight loss drugs keeps growing due to numerous new benefits as well as side effects that are discovered every other day. A recent study found that the risk of aortic aneurysm rupture is significantly less among GLP-1 users. The study was published in the Journal of Vascular Surgery.

GLP-1 receptor agonists is a a class of medicines that is widely used to treat type 2 diabetes and obesity. Users have reported substantial weight loss results with the help of these medicines like Ozempic, Mounjaro, Zepbound and others.

Now, researchers have found that people with abdominal aortic aneurysms who used GLP-1 drugs had a 46% lower risk of rupture over five years compared with those who did not use these medicines. This means that GLP-1 drugs may also have cardiovascular benefit apart from diabetes and obesity.

The study analysed health records from 123 healthcare organisations in the US. It is based on more than 412,000 people diagnosed with abdominal aortic aneurysms who underwent imaging surveillance every six months.

After matching patients based on factors like age, sex, diabetes, high blood pressure, smoking, heart disease and kidney disease, the researchers compared 13,722 GLP-1 receptor agonist users with an equal number of non-users.

After five years, aortic aneurysm rupture was recorded in about 1.6% of people taking GLP-1 drugs, compared to 2.4% of those who were not taking them.

The researchers reported a hazard ratio of 0.538, indicating a 46.2% lower risk of rupture among GLP-1 drug users after adjustment.

The difference was also observed at the two-year mark, when rupture occurred in 1.1% of GLP-1 users compared to 1.8% of non-users.

People taking GLP-1 drugs also had fewer elective aneurysm repairs. At five years, 2.1% of users underwent elective repair compared to 3% of non-users.

The study further found lower rates of major cardiovascular events like heart attacks, strokes and heart failure, as well as lower all-cause mortality among GLP-1 users.

What Is An Abdominal Aortic Aneurysm?

An abdominal aortic aneurysm (AAA) occurs when a section of the aorta, the body's largest artery, becomes enlarged or bulges due to weakening of its wall. It develops in the part of the aorta that passes through the abdomen.

Many abdominal aortic aneurysms do not cause symptoms and are detected during tests. However, as the aneurysm enlarges, its risk of rupture increases.

A ruptured aneurysm is considered to be a medical emergency as it can cause severe internal bleeding. Symptoms may include sudden, severe abdominal or back pain, dizziness, fainting and a rapid heartbeat.

Smoking, older age, high blood pressure, atherosclerosis and a family history of aneurysms are among the risk factors.

GLP-1 Drugs & Lower Risk Of Aortic Aneurysm Rupture Risk

GLP-1 receptor agonists work by mimicking the naturally occurring GLP-1 hormone. They help regulate blood sugar by stimulating insulin release when glucose levels are high, slowing the emptying of stomach and reducing appetite.

Some of their effects may also impact blood vessel health. Abdominal aortic aneurysms develop through several processes, including inflammation, damage to vascular smooth muscle cells and changes in the proteins that maintain the artery wall.

GLP-1 drugs have shown anti-inflammatory and cardiovascular benefits in older research. The researchers suggest these effects may help explain the lower rates of aneurysm-related complications observed in the study.

The findings are promising but do not conclusively prove that GLP-1 medicines prevent aneurysm rupture. This was a retrospective observational study, meaning researchers examined existing health records rather than randomly assigning patients to receive the drugs.

One important limitation was that aneurysm size was not included among the matching variables. Since aneurysm size is a major determinant of rupture risk, differences between the groups could have impacted the findings.

When Missed Periods Are Not Just A Reproductive Issue: What Your Cycle May Be Saying About Your Bones

Updated Nov 1, 2026 | 04:30 PM IST

SummaryMissed or irregular periods may signal hormonal imbalances that affect more than reproductive health. Low oestrogen levels associated with menstrual disturbances can impair bone formation and increase the risk of bone loss.
When Missed Periods Are Not Just A Reproductive Issue: What Your Cycle May Be Saying About Your Bones

Credit: AI

When a woman misses her period, pregnancy is usually the first thing she thinks about. If that is ruled out, stress, weight changes or a hormonal imbalance may seem like the obvious explanations. But when periods become irregular or stop for several months, there may be more to the story.

In some women, these changes can also signal a risk to bone health. The menstrual cycle is controlled by a complex interaction between the brain and the ovaries. Oestrogen, one of the key hormones involved, is important not only for reproductive health but also for maintaining strong bones. It helps regulate the continuous process of bone breakdown and rebuilding.

When oestrogen levels remain low for a prolonged period, this balance can be disturbed, leading to a reduction in bone mineral density and, in some cases, an increased risk of fractures.

Menstrual health is not just about getting a period every month. It can offer important clues about what is happening elsewhere in the body.

Why Do Periods Sometimes Stop?

One possible cause is functional hypothalamic amenorrhoea, a condition in which the brain reduces the hormonal signals that stimulate the ovaries. It may occur when the body is under physical or emotional stress, particularly in the setting of inadequate food intake, rapid weight loss, excessive exercise or a combination of these factors.

In simple terms, the body may not be getting enough energy to support all its normal functions. Reproductive activity can slow down as a result. If this continues, the effects may extend beyond the menstrual cycle.

Low energy availability can affect hormones involved in bone formation and maintenance. Inadequate intake of protein, calcium and vitamin D may further compromise bone health.

The concern is particularly important in adolescents and young women, because these are the years when the body builds much of its peak bone mass. If this process is disrupted, they may not achieve their full bone-strength potential, which can have implications for bone health later in life. It can happen even when a woman is not underweight.

One common misconception is that only very thin women are at risk. In reality, a woman can have a seemingly healthy body weight and still not be eating enough to meet the demands of her daily activity.

A student under academic pressure may skip meals regularly. A working professional may combine long hours with restrictive eating, while a woman who exercises intensively may not increase her food intake to match her energy needs. In such situations, menstrual changes may be one of the first noticeable signs that something is wrong.

Persistent tiredness, declining exercise performance, poor recovery after workouts and recurrent bone or muscle injuries may provide additional clues.

These symptoms are easy to dismiss as the result of a busy lifestyle, but they deserve attention when they occur alongside irregular or absent periods.

Not Every Missed Period Has The Same Cause

Although inadequate energy intake and prolonged stress can affect menstruation, they are not the only explanations. Pregnancy must first be ruled out. Other possible causes include polycystic ovary syndrome (PCOS), thyroid disorders, raised prolactin levels, premature ovarian insufficiency, chronic illnesses and certain medications.

A woman should seek medical evaluation if her periods stop for three months without an explanation, if her cycles remain persistently irregular, or if menstrual changes are accompanied by significant weight loss, restrictive eating, excessive exercise, bone pain or a stress fracture.

The assessment usually begins with a detailed menstrual history and questions about diet, exercise, weight changes, stress and medication use. Depending on the findings, the doctor may recommend pregnancy testing, blood tests to assess thyroid function and reproductive hormones, prolactin levels and other investigations.

A bone mineral density scan may also be appropriate when periods have been absent for a prolonged period or when additional risk factors for bone loss are present.

Protecting Menstrual Health Also Means Protecting Bone Health

Treatment depends on the underlying cause. When inadequate energy availability is responsible, the priority is to restore a healthy balance between food intake, physical activity and recovery.

This may require nutritional guidance, changes to exercise routines and support for managing psychological stress. A gynaecologist may work with an endocrinologist, dietitian or mental-health professional, depending on the individual’s needs.

Adequate calcium, vitamin D and protein are important for bone health, but supplements alone cannot correct an ongoing energy deficit. Similarly, hormonal medication should not be prescribed simply to produce a period without first understanding why menstruation has stopped.

A menstrual cycle is more than a monthly reproductive event. Persistent changes can provide valuable clues about hormonal function, nutrition and overall health. Paying attention to these changes early can help identify underlying problems and, where necessary, protect bone health for the future.
