OBJECTIVE: Isoflavones (ISO) present in soybean are named phytoestrogens because they show estrogen effect. The use of isoflavones has beneficial effect in disturbance of post-menopause, which is characterized by ovarian function suppression. Decreasing of estrogen secretion and consequent morphologic and metabolic disarrangements are observed in female hormonal decline. The aim of present work was to investigate the effect of ISO on the fat accretion of uterin endometric tissue, and HDL and glucose blood concentration from ovariectomized rats (OVX). METHODS: Female […]

To evaluate the benefit of phytoestrogens (PhE) in hormone replacement therapy of menopause (HRTM), the Department of Female Endocrinology of the Brazilian Society of Endocrinology and Metabolism convened a group of specialists to perform a bibliographic review. Only articles that met strict scientific methodological criteria were included. PhE exhibit both estrogenic and antiestrogenic actions, mainly on estrogen (E) receptors b, with much less estrogenic potency than estradiol. PhE content of vegetal sources varies, depending on cultivation, harvesting, storage and industrialization. […]
