At the annual meeting of the Society of Neuroscience in San Diego, scientists suggested that estrogen is beneficial to both men and women. Declining estrogen levels in middle-aged women seems to effect cognitive skills such as remembering under stress according to an article published in the L.A. Times newspaper.

A study of 42 postmenopausal women at the health sciences campus of the University of Southern California found that women who were taking hormone replacement therapy did better at remembering words and judged the grammar of sentences more accurately following some tests.

The tests included putting their hands in icy water for three minutes and then twenty minutes later working with their memory and multitasking skills.

In studies of male songbirds, the researchers found that the males need certain levels of estrogen to help their brains function properly.
