On July 1, 1994, The Press of Atlantic City, NJ, had a headline reading, “Study: Female hormone makes mind keener” (p. A2). Here is part of the report:
Halbreich said he tested 36 post-menopausal women before and after they started the estrogen therapy. He gave each one a battery of tests that measured such things as memory, hand-eye coordination, reflexes and the ability to learn new information and apply it to a problem. After estrogen therapy started, he said, there was a subtle but statistically significant increase in the mental scores of the patients.
