This moderate to large effect size , showing lower ratings of depressed mood in treated patients compared with controls , implicated HRT as a potential treatment of or prophylactic for depression in menopausal women .
One can generalize from the studies review ed here only with great caution , but there is little evidence to support the use of estradiol to improve mood in nondepressed patients ( not surprisingly ) and some evidence to support the antidepressant efficacy of estradiol in perimenopausal but not postmenopausal women
BACKGROUND Controversy regarding the antidepressant efficacy of hormone replacement therapy ( HRT ) stems almost from its inception and reflects the same method ological inconsistencies that have compromised efforts to determine whether the perimenopause is accompanied by an increase in mood symptoms or depression .
Since this publication , multiple studies have aim ed to discern the relationship between HRT and menopausal mood .

Benefits and risks of postmenopausal hormone therapy when it is initiated soon after menopause.
The authors further analyzed results from the Women 's Health Initiative r and omized trials ( 1993 - 2004 ) of conjugated equine estrogens , with or without medroxyprogesterone acetate , focusing on health benefits versus risks among women who initiated hormone therapy soon after menopause . Data from the Women 's Health Initiative observational study ( 1993 - 2004 ) were included in some analyses for additional precision . Results are presented here for incident coronary heart disease , stroke , venous thromboembolism , breast cancer , colorectal cancer , endometrial cancer , or hip fracture ; death from other causes ; a summary global index ; total cancer ; and total mortality . Hazard ratios for breast cancer and total cancer were comparatively higher ( P < 0.05 ) among women who initiated hormone therapy soon after menopause , for both regimens . Among these women , use of conjugated equine estrogens appeared to produce elevations in venous thromboembolism and stroke and a reduction in hip fracture .  Estrogen plus progestin results among women who initiated use soon after menopause were similar for venous thromboembolism , stroke , and hip fracture but also included evidence of longer-term elevations in breast cancer , total cancer , and the global index . These analyses provide little support for the hypothesis of favorable effects among women who initiate postmenopausal estrogen use soon after menopause , either for coronary heart disease or for health benefits versus risk indices considered
