Human eggs remain healthy for decades by putting ‘batteries on standby mode’

Researchers discovered that human egg cells skip a crucial metabolic reaction to maintain their reproductive capacity without losing energy, allowing them to remain dormant in ovaries for up to 50 years. This finding explains why some women with mitochondrial conditions linked to this reaction do not experience reduced fertility.
