Nephron number varies widely in healthy adults. The extent to which this variation is due to differences in nephron endowment at birth and/or nephron loss with ageing is unclear. A recent study used a novel approach to identify a previously unappreciated high loss of nephrons with ageing in healthy kidneys.
