THIS IS MY LAST QUESTION AND IS DUE IN 7 HOURS HELPP

After menopause many women take supplemental estrogen. There is some concern that if these women also drink alcohol, their estrogen levels will rise too high. Twelve volunteers who were receiving supplemental estrogen were randomly divided into two groups, as were 12 other volunteers not on estrogen. In each case, one group drank an alcoholic beverage, the other a non-alcoholic beverage. An hour later everyone’s estrogen level was checked. Only those on supplemental estrogen who drank alcohol showed a marked increase.
