Dr. Shanna Swan is a Reproductive Epidemiologist. She believes sperm counts are declining among men. Last year Dr. Swan did some research of her own, looking at university and college-aged males in Rochester, New York, and found that sperm quality was not great; in fact, 23 percent had counts that would be grounds for going to see the fertility doctor. Other scientists, however, believe that instead of worrying about the quality of sperm, we should be worrying about the quality.
