PARIS (AFP) - Men who watch television for 20 hours per week have almost half the sperm count of those who watch very little television or none at all, according to a study published on Tuesday.

United States researchers recruited 189 young men aged between 18 to 22, questioned them about their exercise, diet and TV habits and asked them to provide a sperm sample.

Men in the top quarter of TV-watchers - those who watched for 20 hours or more - had a 44 per cent lower sperm count than those who watched least, meaning they said they watched "none or almost none". Another big factor was exercise, according to the study, published online in the British Journal of Sports Medicine.

Men who exercised for 15 or more hours weekly at a "moderate to vigorous" rate had a 73 per cent higher sperm count than those who exercised less than five hours per week.
