UCI study helps identify one reason why women have lower stroke risk than men
Estrogen’s role as an inhibitor of toxic-free radicals in cerebral blood vessels may be a key reason why premenopausal women have a lower stroke risk than men.
According to UC Irvine School of Medicine researchers, estrogen has a powerful and positive influence on women’s health by increasing the energy production efficiency of mitochondria – the tiny power plants that provide cells the energy they need to function. And in doing so, the hormone inhibits the mitochondrial production of free radical oxygen molecules. Previous studies have shown that excessive amounts of these radical elements in the body, through a process called oxidative stress, can damage blood vessels and lead to stroke or degenerative disease.
