Lack of evidence most IVF ‘add-ons’ improve fertility

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.
