Effects of estradiol on biological age measured using the glycan age index
Jurić et al.
Aging (Albany NY)
Objective
Assess the impact of estrogen on biological aging in women.
Methods
Menopause was experimentally induced in 36 healthy young women by suppressing their natural estrogen production. Participants were then randomized to receive either transdermal estrogen therapy or placebo.
Results
Women who had their estrogen production suppressed showed an average increase of 9.1 years in their biological age. This increase was completely abolished in women who received estrogen supplementation.

Conclusion
Estrogen depletion, similar to what occurs in menopause, leads to a sharp rise in biological age. However, estrogen supplementation, as seen in hormone replacement therapy, counteracts this effect, highlighting its potential to reduce biological age.
