What happens in the ovaries postmenopause?

Available for over a year

Perhaps contrary to popular belief, it is not all over for ovaries once a woman is post-menopausal. In a study published in Aging Cell, researchers studying the ovaries from 28 women found that even though their reproductive function ceases, the ovaries remain biologically active and continue to change in the decades after menopause. Francesca Duncan from the Department of Obstetrics and Gynaecology at Northwestern University and the Buck Institute for Research on Aging joins Claudia to discuss the findings. Joining Claudia from Ghana is Vanessa Apea, a genito-urinary consultant and HIV expert. Providing another piece of the food allergy jigsaw puzzle, they discuss new research which has found that eating eggs and peanuts in pregnancy and whilst breastfeeding does not protect infants from developing those allergies. Pooled tuberculosis testing could halve costs and help identify millions of missing cases, finds a new study published in The Lancet Global Health. The strategy involves testing combined samples from multiple patients and only individually retesting if a pooled test comes out positive. Joining Claudia to discuss are Mbuli Cyrille, technical assistant with the National Tuberculosis Control Program in Cameroon and Tom Wingfield, an infectious diseases doctor and researcher at the Liverpool School of Tropical Medicine. Claudia and Vanessa also discuss research just presented at the European Academy of Dermatology and Venereology (EADV) Congress 2026 in Vienna which has found that nail detachment and discolouration is more common among GLP-1, weight loss drug, users. Why might this be? And a new study, published in the journal Clinical Gastroenterology and Hepatology suggests that late-night eating has been found to be bad for your liver. Health Check examines these findings. Presenter: Claudia Hammond Producers: Helena Selby & Jonathan Blackwell
