Many people with infertility use in vitro fertilisation (IVF), however the probability of having a baby following IVF is only approximately 30-40% per cycle and decreases significantly with age. It can be a lengthy and expensive process. Providers sometimes offer ‘add-ons’, additional treatments that they claim could help patients conceive, which are themselves also usually expensive. In Australia, New Zealand and the United Kingdom more than 70% of patients pay for at least one of these add-ons. A new review published in The Lancet Obstetrics, Gynaecology, & Women’s Health journal has found that evidence on the benefits of these add-on treatments is unclear. Claudia Hammond speaks to Dr Sarah Lensen, Senior Research Fellow in the Department of Obstetrics, Gynaecology and Newborn Health at the University of Melbourne. Joining Claudia from Ghana is genito-urinary consultant and HIV expert, Vanessa Apea. Claudia and Vanessa discuss a draft African Charter on Family, Sovereignty and Values, which claims that comprehensive sex education, as well as a range of sexual and reproductive health rights, are a threat to African families from foreign ideologies. They also discuss a report from the Office of Inspector General of US Agency for International Development (USAID) which reveals that President Donald Trump’s administration has spent hundreds of thousands of dollars in storage and transportation costs for $9.7 million worth of contraceptives that are being stored in Belgium rather than distributed to the various low-income countries they were intended for. Many of the withheld contraceptives are now expired or unusable due to their removal from temperature-controlled storage. We also hear from Health Check reporter Jane Chambers in the Chilean city of Valdivia, where wetlands are part of everyday life—and increasingly, part of people’s health. And we hear how faecal-microbiome transplants could improve the efficacy of some antidepressants in patients with major depressive disorder.

The American Food and Drug Administration (FDA) has just awarded fast track status to three companies developing psychedelic drugs as a treatment for addiction and other mental health issues. It comes after President Trump directed $50million dollars to increase their availability. Claudia Hammond is joined by BBC Brazil reporter Camilla Mota to discuss what claims are made for the effectiveness of these drugs. A novel house design, called “Star Homes”, which promote airflow, block insects, and feature rainwater collection systems, can reduce child mortality, demonstrated by a randomised controlled trial in Tanzania. We hear from Professor Lorenz Von Seidlein from the Mahidol-Oxford Tropical Medicine Research Unit in Bangkok about what makes these homes effective in lowering rates of malaria, diarrhoea and acute respiratory infections. We hear that the Russian health minister has called for 1 in 3 Russians to be tested for HIV annually. Russia has long had high rates of HIV, but it now has the highest prevalence in Europe, with particularly high rates among Russian troops since the beginning of the Ukraine war.

We learn about a new injectable microgel to help reduce bleeding in infants who require surgical care. In a mice model, it reduced bleeding by at least 50%. Ashley Brown, Professor of Biomedical Engineering at North Carolina State University and UNC Chapel Hill tells presenter Claudia Hammond more about this new material her team has designed. Joined by Professor of Global Health and Epidemiology at Boston University in the US, Dr Matthew Fox, Claudia hears about a mystery illness that is being investigated by health officials in Burundi, which has caused five deaths and sickened thirty-five people. So far lab analysis of the illness - which causes fever, vomiting, and diarrhoea - has been negative for Ebola and Marburg viruses, Rift Valley fever, and others. We hear about influential analysis from Cochrane which has concluded that "breakthrough" Alzheimer's drugs are unlikely to benefit patients. Researchers said the impact was "well below" what was needed to make a difference to dementia patients' lives. However, their report has also provoked a vicious backlash from equally esteemed scientists who label it as fundamentally flawed. We’re joined by health journalist Katie Silver in Mexico, who brings us the news that the President, Claudia Sheinbaum, has announced the details of a plan to introduce universal healthcare – no mean feat in country of 130 million people. And we hear about an experiment that was done by academics to see if they could trick AI chatbots into believing in an entirely fake disease. Presenter: Claudia Hammond Producer: Jonathan Blackwell

A minority of patients requiring blood transfusions are increasingly requesting ‘unvaccinated’ blood in the United States, per a new report published in the journal Transfusion. Our studio guest today, genito-urinary consultant Vanessa Apea, explains how this can lead to potentially dangerous delays and higher risks. Presenter Claudia Hammond speaks to Dr Angela Wu, from the Centre for Evidence-Based Medicine and Oxford Tobacco Addiction Group at the University of Oxford, about a new overview of the best available evidence worldwide for smoking cessation. The study, published in the journal Addiction, has found that nicotine‑containing e‑cigarettes appear to be more effective for stopping people smoking than other interventions. We hear how metabolic liver disease could affect nearly 1.8 billion people by 2050, according to new research published in The Lancet Gastroenterology & Hepatology journal. The growing number of cases means that many people are at risk of developing serious complications, however, the study also found that although more people are developing the disease, the overall impact on health has remained stable due to advances in treatment and care. We also hear from BBC World Service reporter Sen Nguyen in Vietnam as Hanoi plans to pilot a new low-emission zone from July to tackle air pollution. We hear what the proposed changes are and with the prevalence of diesel motorbikes in the city, how prepared are residents, workers and businesses for this change?

New research from Yale shows that aging doesn’t have to result in mental and physical decline. In fact, they found that nearly half of older adults actually improved in cognitive or physical ability over a 12-year period. Dr Graham Easton, a family doctor, discusses what this can teach us about what we can and can’t control when it comes to aging. Brain tumours can be notoriously difficult to treat because many therapeutic drugs are not allowed through the blood-brain barrier – an extremely selective system that controls access in and out of the brain. Now, researchers at the University of Southern California have shown that laser-induced tumour heating can open blood-brain barrier, improving the effectiveness of immunotherapy in brain cancer. Erika Benke reports from Finland, where the Winter Swimming World Cup is underway, looking at why winter swimming is growing in popularity and what researchers say about its real health effects and risks. A once‑rare form of organ donation is now transforming transplant care in the U.S and other countries, offering hope to thousands on waiting lists.

Many of us can empathise with that feeling of keeping stuff for years and years. We might keep treasured objects with real sentimental value, or we might have items for a long time - and yet we can't really explain why. For those of us who don’t like getting rid of our belongings, life can feel very full of stuff. But when does a tendency to hold on to things become more worrying? It can be difficult to put a figure on just how many people have what's known as hoarding disorder. So what causes this complex and little discussed issue – and is it more than just a problem of too much stuff? Claudia visits a woman who describes how hoarding has taken over her life to the extent that she doesn’t let anyone into her home. We also meet her psychologist to understand what underpins hoarding disorder and how it’s treated. And joining us in the studio is Catherine Loveday, Professor of Cognitive Neuroscience at the University of Westminster to look at whether our state of mind when we get vaccinated affects how well the vaccine works.

In the past decade there has been little progress in lowering malaria cases, with over half a million people still dying from the mosquito-borne disease every year. We look at the big ideas and innovations of the future that could help us eliminate malaria once and for all. What would happen if we got rid of the insect responsible for spreading the malaria parasite? Claudia heads to Imperial College London where she is joined by Dr Federica Bernardini and their 120 colonies of mosquitos to find out how revolutionary genetic technologies are aiming to do just that. Picking up on Imperial’s work in the field is Principal Investigator at Target Malaria in Uganda, Dr Jonathan Kayondo. His job is to understand what it would mean to release these modified mosquitos into the wild. Looking at the existing tools that need levelling up is Dr Rob Moon, from the London School of Hygiene & Tropical Medicine, and Dr James Tibenderana, Chief Executive at the Malaria Consortium. Alongside Claudia they look at the next generation of vaccines and the importance of accessible rapid diagnostic tests. But is all this going to be enough to eliminate malaria?

Malaria is still the third biggest killer on the planet and despite decades of serious investment it’s a disease that is still very much with us. But that investment is starting to pay off - 2025 has been a big year for new ways of tackling the disease. This week we’re reflecting on the progress made in 2025 – but also asking what impact unprecedented cuts to global health funding might have on whether children living in hot and humid regions of the world contract malaria. Our expert guide is James Tibenderana, an epidemiologist from Uganda. He is Chief Executive at the Malaria Consortium, an organisation that advises governments on best practice for tackling malaria as well as delivering their own programmes. We also hear from Nigeria, the country with the highest rates of malaria in the world. Dr Onyinye Echedike-Elekwa at The University of Port Harcourt Teaching Hospital on the south coast of the country tells us how it’s been in the clinic this year. The drug known as GamLun marks a huge breakthrough in the treatment of malaria. Abdoulaye Djimdé is Professor of Parasitology and Mycology at the Malaria Research and Training Centre University of Bamako, Mali. He led clinical trials of the medication and explains how it works. In September, the World Health Organisation announced conditional approval for indoor use of spatial emanators, a device which continually releases a mosquito toxin into the air for up to a year. Epidemiologist Ellie Sherrard-Smith from the Liverpool School of Tropical Medicine in the UK explains the potential benefits and concerns for this tool. Plus, we reflect on the progress made in the malaria vaccine roll out this year and how a new formulation of a pre-existing drug is offering hope to the very youngest patients And could we ever eliminate malaria completely? Next week, we consider the big ideas hoping to do just that. With thanks to Karina Igonikon Presenter: Claudia Hammond Producer: Hannah Robins

Do you look back on the past with rose-tinted spectacles, memories of the good old days accompanied by warm, fuzzy feelings? Or when you reflect on the past is it hard to do so without a tinge of sadness? Whether you fall on the more bitter or more sweet side, this is the bittersweet feeling of nostalgia. But nostalgia was not always just a feeling. Historian Agnes Arnold Forster tells Claudia and the panel that once it was viewed as a disease so deadly that it appeared on thousands of death certificates. And now this poignant emotion stirs political action, bonds us to others, and guides our very understanding of ourselves. Our expert panel of psychologists; Peter Olusoga, senior lecturer in psychology at Sheffield Hallam University, Daryl O’Connor, professor of psychology at the University of Leeds, and Catherine Loveday, professor of cognitive neuroscience at the University of Westminster, join Claudia in the studio to discuss how leaning into nostalgia can help us feel better, reduce pain, and even inject a bit of romance into life.
