Another menopausal myth is challenged: Women with existing coronary disease do not realize improvement in their cognitive function as a result of taking the most common form of hormone replacement therapy, a UCSF study has found. Investigators followed more than 1000 women from ten US test sites for four years. Half took a placebo; the other half took hormone replacement therapy (HRT). Although other, smaller studies have shown an improvement, in the UCSF study the women who received HRT performed no better on standard tests of cognitive function than those who received placebo.
Excessive bleeding, a troublesome side-effect that causes many women to stop taking hormone replacement therapies (HRT), is less likely with progesterone than with more commonly used synthetic versions. Results from a national clinical trial published in the November issue of the Journal of Obstetrics and Gynecology, show that a combination of estrogen and micronized progesterone (MP) causes fewer days and less intense bleeding than the most commonly used combination. Previous studies have shown that unacceptable bleeding is the reason that most women discontinue HRT during the first year of therapy.
