In the first study to explore the role of estrogen in working memory function in premenopausal women, researchers at McGill University have documented a significant decrease in working memory among women whose estrogen levels were suppressed by chemicals, not age.

The prospective study, published online in the journal Psychoneuroendocrinology, monitored estrogen levels and working memory among 25 women between 25 and 40 years of age being treated for benign gynecological problems (fibroids, uterine polyps, endometriosis) in the Department of Obstetrics and Gynecology at the McGill University Health Centre.
