There is no evidence of effectiveness in the alleviation of  menopausal symptoms with the use of phytoestrogen treatments
BACKGROUND Vasomotor symptoms , such as hot flushes and night sweats , are very common during the menopausal transition .
Hormone replacement therapy has traditionally been used as a very effective treatment but concerns over increased risks of some chronic diseases have markedly increased the interest of women in alternatives .
Some of the most popular of these are treatments based on foods or supplements enriched with phytoestrogens , plant-derived chemicals that have oestrogenic action .
OBJECTIVES To assess the efficacy , safety and acceptability of foods and supplements based on high levels of phytoestrogens for reducing hot flushes and night sweats in postmenopausal women .
Benefits of soy germ isoflavones in postmenopausal women with contraindication for conventional hormone replacement therapy.
OBJECTIVE To evaluate the effects of isoflavones on vasomotor symptoms and blood lipids in postmenopausal women with contraindication for conventional hormone replacement therapy ( HRT ) . METHODS This prospect i ve , double-blind and placebo-controlled study included 50 postmenopausal women r and omly divided into two groups : 25 women on soy germ isoflavones ( 60 mg per day , capsules ) and 25 women on placebo .  Inclusion criteria included : non-vegetarian , non-asian women whose last menstruation date d at least 12 months prior to the beginning of the study , with FSH > 40 mIU/ml , hot flushes and contraindication for HRT , not using tamoxifen or antibiotic and no disease of the gastrointestinal tract . For 6 months , the Kupperman menopausal index ( KMI ) , the vaginal cytological maturation value ( MV ) and both hormonal and lipid profiles were assessed . The t-test and analysis of variance ( ANOVA ) were employed to compare the two groups . RESULTS In both groups , a decreased KI rate was observed . However , isoflavone was significantly superior to placebo in reducing hot flushes ( 44 % versus 10 % , respectively ) ( P < 0.05 ) . After 6 months , the isoflavone group showed increased estradiol levels with unchanged FSH , LH , and vaginal cytology , and a reduction of 11.8 % in LDL and an increase of 27.3 % in HDL ( P < 0.05 ) . In the placebo group , just a reduction in MV was observed after 6 months ( P < 0.05 ) . CONCLUSIONS Soy germ isoflavone exerted favorable effects on vasomotor symptoms and lipid profile , showing itself to be an interesting alternative therapy for the postmenopausal women with contraindication for conventional HRT
