Sperm slows the ageing process


A new study by scientists at Graz University found that spermidine, a compound that is found in sperm, slows ageing processes and increases longevity in yeast, flies, worms and mice, as well as human blood cells, by protecting cells from damage.

Cell ageing happens when a natural process called autophagy – a sort of cellular cannibalism whereby damaged cells or parts of cells are recycled – goes wrong.

Spermidine concentration has been shown to decline with age.

Adding spermidine suppressed various processes associated with ageing, as well as reducing free radicals and increasing lifespan. Treated fruit flies lived 30 per cent longer than untreated ones, while worms lived 15 per cent longer.
