A recent study on medical treatment suggests that physicians need to pay more attention to gender when they diagnose and treat their patients for various conditions and ailments.

Physicians are now beginning to realize they have to treat and educate female and male patients differently. Angela Manieri is a good example. After her father's heart attack, she began taking a daily dose of aspirin, because her father told her to do so.  She says, "My Dad went through a bad quadruple bypass. I want to prevent that from happening to me."

Angela's cardiologist told her that was the wrong thing to do; only men took part in a study showing a daily dose of aspirin could prevent heart attacks. New research shows that taking aspirin daily could actually hurt, instead of help, women.  A report by the Society for Women's Health Research, shows more research is needed to determine how men and women respond differently to disease.

Sherry Marts, the group's vice president for Scientific Affairs says, "Biologically, we are very different. We are different on the genetic level."

NASA, the United States' space agency, is also studying the genetic and physiological differences in men and women. Scientists say studying the differing effects of space travel on male and female astronauts has led to new information about bone loss and cancer.
