In breakthrough, Jerusalem lab says older human eggs can be made young again – Ova from women 40+ took on some characteristics of eggs from a 20-year-old after treatment with anti-viral medicine; Hebrew University team hopes method may boost fertility | Timesofisrael

A Jerusalem lab says it has “reverse aged” human eggs from women at the end of their child-bearing years to make them more like eggs from a 20-year-old.
In new peer-reviewed research published Tuesday, scientists from the Hebrew University of Jerusalem said that they identified a previously unknown aging mechanism, and say they can reverse it by administering anti-viral drugs to the egg in a test tube.
