Study links body image to athletes' fertility

University Park, Pa. --- A Penn State study of female athletes has linked psychological stress resulting from a poor body image, along with inadequate diet and excessive exercise, to transient menstrual disturbances that could render a woman temporarily infertile.

Dr. Nancy I. Williams, assistant professor of kinesiology and director of the study, says, "Most people are comfortable with telling women athletes who experience menstrual abnormalities simply to eat more and exercise less but our research is beginning to show that eating and exercise aren't the only factors.

Only 19 percent of the non-athletes reported abnormal cycle lengths.

Williams notes, "What was surprising wa
