Summary

Story summary

Scientists report rejuvenating human eggs using Shugoshin 1 protein, boosting in vitro fertilization (IVF) success for older women.
In treated eggs, chromosomal abnormalities dropped from 53% to 29%, indicating improved genetic quality.
The approach aims to improve egg quality but does not extend fertility beyond menopause, though it could help more women conceive in IVF.
Findings will be presented at British Fertility Conference and shared as a preprint on Biorxiv.
