Some parts of your body are inherently sensitive. So, it is understandable if the idea of using something called "low-intensity shockwave therapy (LISWT)" to treat erectile dysfunction (ED) makes you squirm. However, research has shown that this method is emerging as a potential treatment for ED, targeting the root cause of vascular issues that impede blood flow to the penis. It is pertinent to note that although this therapy is promising, it is not yet FDA-approved and remains experimental.

Here's How LISWT Works

Shockwave therapy is a non-invasive treatment that uses sound waves to help heal damaged tissues. In the case of ED, this therapy stimulates and strengthens blood vessels in the penis, improving blood flow and supporting erections. Initially developed to treat kidney stones and chronic wounds, LISWT’s use in ED is relatively new but has shown positive results in treating vascular ED.

This treatment is effective ...

• For individuals with mild to moderate vascular ED.
• For patients who respond well to ED medications like sildenafil (Viagra)
• It is not suitable for ED caused by nerve damage or psychological factors.

Around 75% of patients report satisfactory improvements. This procedure involves multiple 15-minute sessions over a month and results last one to two years, and the treatment is pain-free for most patients. However, this treatment is costly, averaging over $3,000, and is often not covered by insurance due to its experimental status. At-home devices are not effective, as they typically use radial wave therapy, which lacks the energy needed to address ED.

What Is Erectile Dysfunction?

Erectile dysfunction, also named impotency or impotence, is a penile disorder that affects an individual’s ability to get or hold an erection during sexual intercourse. During intimate moments, one's feelings share a pivotal role in getting and keeping an erection firm.

For this, one may feel confident, relaxed and aroused. While problems with erection are normal sometimes, they can occur due to causes such as psychological conditions, prescription drugs, and underlying health conditions. Excessive smoking or drinking can also trigger the condition.

Symptoms of Erectile Dysfunction (ED)

Occasional Erections: Difficulty achieving an erection consistently before sexual intercourse.

Erection Maintenance Issues: Ability to achieve an erection but difficulty maintaining it during intercourse.

Complete Inability: Inability to achieve an erection at all.

Dependence on Stimulation: Constant need for external stimulation to maintain an erection.

Reduced Libido: Decreased sexual desire experienced by some individuals with ED.

Can ED Be Prevented?

Yes, ED is preventable. Adopting a healthy lifestyle can help to prevent erectile dysfunction. Additionally, changes such as quitting smoking, limiting alcohol intake, engaging in cardiovascular exercises (jogging, running, swimming or bicycling), consuming a low saturated fat diet (fruits, whole grains and vegetables), maintaining a healthy weight and getting quality sleep can be immensely beneficial in the prevention journey.

As artificial intelligence becomes a go-to source for quick answers, a new University of Oxford-led study on AI chatbots and medical advice is raising serious concerns about how safe it is to rely on these tools for health guidance.

The research suggests that while AI chatbots can provide medical information, their advice is often inaccurate, inconsistent, and difficult for users to interpret, potentially putting people at risk—especially when dealing with symptoms that need urgent care.

What the Oxford Study Found

The study involved 1,300 participants who were given realistic health scenarios, such as experiencing a severe headache or being a new mother feeling constantly exhausted. Participants were divided into two groups: one group used AI chatbots to understand their symptoms and decide next steps, while the other did not.

Researchers then assessed whether participants correctly identified what might be wrong and whether they made appropriate decisions, such as seeing a GP or visiting A&E.

The results were troubling. People who relied on AI frequently failed to identify the severity of their condition and were often unsure about when to seek professional medical help.

Why Chatbot Advice Can Go Wrong

According to the researchers, one major issue is that people don’t always know what to ask. The study found that chatbot responses varied widely depending on how questions were phrased. Even small changes in wording could lead to completely different answers.

The AI often produced a mix of helpful and misleading information, leaving users to decide which advice mattered. Many participants struggled to distinguish between reliable guidance and unnecessary or confusing details.

As one of the study’s authors explained, when an AI lists multiple possible conditions, users are left guessing which one applies to them—precisely the moment where mistakes can happen.

A Dangerous Gap in Symptom Interpretation

Dr Rebecca Payne, lead medical practitioner on the study, warned that asking chatbots about symptoms could be “dangerous”, particularly when users delay seeking professional care based on AI responses.

Dr Adam Mahdi, the study’s senior author, noted that while AI can share medical facts, people often share information gradually and leave out key details—something chatbots struggle to manage effectively.

Bias, Data, and the Limits of AI

Experts also point out that chatbots are trained on existing medical data, which means they may repeat long-standing biases baked into healthcare systems. As one psychiatry expert put it, a chatbot is only as accurate as human clinicians—and humans are far from perfect.

That said, not everyone is pessimistic.

What Comes Next for AI in Healthcare

Digital health experts argue the technology is evolving. Health-specific versions of general AI chatbots have recently been released by major developers, and these could perform differently in future studies.

The consensus among experts is clear: AI in healthcare should focus on improvement, regulation, and guardrails, not replacement of doctors. Used responsibly, it may support healthcare—but without safeguards, it risks doing more harm than good.

This common pregnancy drug could be linked to cancer. Wes Streeting has been urged to launch a public inquiry into a miscarriage drug called Diethylstilbestrol, which, reports say has "ruined and devastated" the lives of countless women. On Monday, the Health Secretary Streeting met victims of the pregnancy drugs, which has been linked to cancer, early menopause and infertility.

What Is Diethylstilbestrol?

Diethylstilbestrol, commonly known as DES, is a synthetic form of female hormone estrogen, which was prescribed to thousands of pregnant women from 1940 to 1970s.

The drug was used to prevent miscarriage, premature labor and complications of pregnancy. This was also used to suppress breast milk production, as an emergency contraception and to treat symptoms of menopause.

What Is The DES Controversy?

In 1971, Diethylstilbestrol (DES) was linked to a rare cancer of the cervix and vagina known as clear cell adenocarcinoma, prompting US regulators to advise that it should no longer be prescribed to pregnant women. Despite this, the drug continued to be given to expectant mothers across parts of Europe until 1978. DES has also since been associated with other cancers, including breast, pancreatic and cervical cancers, The Telegraph reported.

Campaign group DES Justice UK (DJUK) is now urging Health Secretary Wes Streeting to order a public inquiry and introduce an NHS screening programme to identify people who may have been exposed to the drug before birth.

Victims described DES as “one of the biggest pharmaceutical scandals this country has ever seen,” warning that “the impact of this terrible drug cannot be underestimated as it has ruined and devastated so many lives,” according to The Telegraph.

In November, Streeting acknowledged that the “state got it wrong” and issued an apology to those affected. He also advised anyone who believes they may have been exposed to DES to speak to their GP.

Susie Martin, 55, from Manchester, whose mother was prescribed DES during pregnancy, told The Telegraph she has undergone between 20 and 30 operations as a result of the drug’s effects.

“The impact of this terrible drug cannot be underestimated as it has ruined and devastated so many lives, including my own,” she said. “The physical and emotional pain has been unbearable. I live with a constant fear that I will need more surgery or develop cancer—and I am far from the only one.”

Calling DES a “silent scandal,” Martin said she hopes the government’s engagement will lead to concrete action. “While I welcome Mr Streeting meeting us, it will only matter if he commits to meaningful steps for victims of this shameful chapter in British medical history, including a screening programme and a full statutory public inquiry,” she added.

What Is Happening With The DES Victims?

The Telegraph reported that compensation schemes have been set up for DES victims in the US and Netherlands, however, UK does not have one yet.

"There are harrowing accounts of harm caused by the historic use of Diethylstilbestrol (DES). Some women and their relatives are still suffering from the associated risks of this medicine which have been passed down a generation, and haven’t been supported. The Secretary of State has been looking seriously at this legacy issue and carefully considering what more the government can do to better support women and their families who have been impacted. NHS England has alerted all cancer alliances to this issue so that healthcare professionals are aware of the impacts of DES and the existing NHS screening guidance which sets out the arrangements for those who show signs and symptoms of exposure,” said a Department of Health and Social Care spokesman to The Telegraph.

The World Health Organization (WHO)'s Montreal meeting focused on wearable technology like smartwatches and activity trackers as a reliable source of health tracking. The meeting discussed that wearables could in fact generate objective real-time data, which helps governments design targeted and evidence-based health interventions.

Physicians in the Montreal meetings discussed that wrist-worn devices are more reliable than traditional self-reported surveys. This is because the self-reported surveys could underestimate the levels of physical inactivity.

“Metrics such as step count, moderate-to-vigorous physical activity and sedentary time directly correlate with cardiovascular disease, diabetes and mental health outcomes. Having population-level data allows for early and preventive strategies,” said Dr Venkat Nani Kumar, consultant in internal medicine.

WHO Montreal Meeting: How Have Doctors Reacted The Shift To Wearables?

Doctors in India have welcomed this shift to wearable devices as a better way to generate data and make policies. Dr Kiran Madhala, professor at Gandhi Medical College, Secunderabad, said WHO’s shift reflects rapid advances in artificial intelligence and digital health tools, calling it a progressive step towards improved monitoring of physical activity worldwide.

City-based doctors also underlined the need for inclusive validation of devices. “Wearables must recognise varied movement patterns and step equivalents, especially in ageing populations,” a physician said, while stressing the importance of data privacy and ethical use of health information.

WHO Montreal Meeting: What Are Wearable Health Devices?

As per a 2022 study published in JMIR MHealth and UHealth, wearables refer to devices that are worn by individuals. In health care field, they assist with individual monitoring and diagnosis. Wearables are “seamlessly embedded portable computers...worn on the body," notes another 2018 study published in Telematics Informatics.

A 2018 study published in the journal Sensors noted that wearable health devices are increasingly helping people to better monitor their health status both at an activity/fitness level for self health tracking and at a medical level providing more data to clinicians with a potential for earlier diagnostic and guidance of treatment.

WHO Montreal Meeting: What Are Some Examples Of Wearables?

Blood Pressure Monitor
