Study links diet to low sperm counts
Harvard Medical School in Boston have studied 99 men attending a US fertility clinic, questioning them about their diet and analysing sperm samples over the course of four years.
The study showed that compared with those eating the least fat, men with the highest fat intake had a 43 per cent lower sperm count and 38 per cent lower sperm concentration (number of sperm per unit volume of semen), and men consuming the most omega-3 fatty acids had sperm with a more normal structure than men with the lowest intake.
This was a relatively small study and there were other limitations, but commenting on the research, British fertility expert Dr Allan Pacey, of the University of Sheffield, said "... it does add weight to the argument that having a good healthy diet may benefit male fertility as well as being good general health advice."
