London: The level of physical activities may significantly affect men`s sperm quality, a new study has suggested.Researchers at Harvard School of Public Health (HSPH) found that healthy young men who were sedentary, as measured by hours of TV viewing, had lower sperm counts than those who were the most physically active."We know very little about how lifestyle may impact semen quality and male fertility in general so identifying two potentially modifiable factors that appear to have such a big impact on sperm counts is truly exciting," said lead author Audrey Gaskins, a doctoral student at HSPH.Gaskins and her colleagues analyzed the semen quality of 189 men between the ages of 18 to 22 participating in the Rochester Young Men`s Study during 2009 at the University of Rochester. The men were asked about their physical activity and TV-watching habits, in addition to health issues that may affect their sperm quality, such as diet, stress levels, and smoking.
