Utility of the phytoestrogens in gynecologyIntroduction: Phytoestrogens are compounds of plant origin, nature of steroids, but with structural similarities to estrogen, both natural (17-stradiol) and synthetic. Major known phytoestrogens are lignans (enterodiol and enterolactone, secoisolariciresinol, matairesinol, nordihidroguairetico acid), the cumestans (coumestrol, metoxicumestrol), isoflavones (genistein, daidzein, biochanin A, glycitein and formononetin) and resorcinol derivates. Objective: Know the benefits of phytoestrogens and the evidence that exists on its use in clinical practice in gynecology. Methodology: We conducted a literature search of electronic databases, PubMed, Ovid, Elsevier, Interscience, EBSCO, Scopus, SciELO. Results: Meta-analysis were reviewed, randomized controlled trials as well as articles whit case series or descriptive, but everybody had a limited number of patients. Conclusions: Different studies have shown that an increased intake of phytoestrogens in foods, along with a regular diet and adding supplements phytoestrogenic, relates to an improved quality of life and health of women and relief significant signs and symptoms of the climacteric syndrome.
