Key Points
-
Estrogen has drawn some serious attention regarding its health benefits.
-
The fact that estrogen replacement therapy (ERT) may predispose women to a much higher incidence of breast and endometrial cancers has undoubtedly compromised or jeopardized its clinical application.
-
A plant-derived phytoestrogen, α-zearalanol (α-ZAL), has been proposed as a potential replacement for estrogen.
-
α-ZAL has shown beneficial effects on blood vessels, osteoporosis, and Alzheimer’s disease in animal models of menopause similar with estrogen.
-
It has less proliferating effects on uterus and mammary gland compared to estrogen.
