Estrogen Helps Fight Pain

by Colette Bouchez

A woman's tolerance of pain may have more to do with the power of her reproductive hormones than the strength of her muscles.

That's the theory a group of Michigan researchers presented Feb. 18 at the annual meeting of the American Association for the Advancement of Science in Denver.

"Our studies have shown that although pain is influenced by both genetics and brain chemistry, it is clear that gender and hormones also play a role in our individual response to pain," says Dr. Jon-Kar Zubieta, lead researcher and a University of Michigan neuroscientist.
