Four trials that were not combined in meta-analyses suggested that extracts with high ( > 30 mg/d ) levels of genistein consistently reduced the frequency of hot flushes .
BACKGROUND Vasomotor symptoms , such as hot flushes and night sweats , are very common during the menopausal transition .
Hormone therapy has traditionally been used as a highly effective treatment , but concerns about increased risk of some chronic diseases have markedly increased the interest of women in alternative treatments .
Some of the most popular of these treatments are foods or supplements enriched with phytoestrogens-plant-derived chemicals that have estrogenic action .
OBJECTIVES To assess the efficacy , safety and acceptability of food products , extracts and dietary supplements containing high levels of phytoestrogens when compared with no treatment , placebo or hormone therapy for the amelioration of vasomotor menopausal symptoms ( such as hot flushes and night sweats ) in perimenopausal and postmenopausal women .
Value of ovarian stromal blood flow velocity measurement after pituitary suppression in the prediction of ovarian responsiveness and outcome of in vitro fertilization treatment.
OBJECTIVE To evaluate whether ovarian stromal blood flow velocity after pituitary suppression is predictive of ovarian response and the outcome of IVF treatment in patients with normal basal serum FSH levels and to compare the predictive value of this test with age , early follicular phase serum FSH level , E2 level , and FSH : LH ratio . DESIGN Prospect i ve observational study of women undergoing IVF treatment .  SETTING A tertiary referral center for assisted reproduction . PATIENT(S ) Eighty-eight women who received the long buserelin acetate treatment protocol .  INTERVENTION(S ) Transvaginal color and pulsed Doppler measurement of the ovarian stromal peak systolic velocity ( PSV ) after pituitary suppression and measurement of the basal serum FSH level , E2 level , and FSH : LH ratio .  MAIN OUTCOME MEASURE(S ) Number of mature oocytes retrieved and pregnancy rate . RESULT ( S ) Ovarian stromal PSV was the most important single independent predictor of ovarian response in patients with a normal basal serum FSH level , when compared with age , basal FSH level , E2 level , or FSH : LH ratio . Patients in group 2 ( PSV > or = 10 cm/s ) had a significantly higher median number of mature oocytes retrieved ( 11 versus 5.5 ) and a higher clinical pregnancy rate ( 35.3 % versus 11.3 % ) than patients in group 1 ( PSV < 10 cm/s ) , even after controlling for age . CONCLUSION ( S ) Ovarian stromal blood flow velocity , after pituitary suppression is confirmed , is predictive of ovarian responsiveness and the outcome of IVF treatment
