of 27 to 38 percent while alcohol was detectable in the blood (Coutelle et al. 2004). This effect was observed during all phases of the menstrual cycle.For postmenopausal women, an increase of estrogens following alcohol consumption appears to depend on whether they use hormone replacement therapy (HRT) to treat menopausal symptoms. In women without HRT, estrogen increases were variable and depended on multiple factors. In women with HRT, the increase in estrogen levels was consistent and pronounced (Singletary and Gapstur 2001).
