Junk Food Shown To Cause Infertility In Younger Men

A joint American and Spanish study released this week shows that Junk food, especially foods with trans fats, can make healthy young men infertile by damaging their sperm.
Fertility experts from Harvard University and the University of Murcia, in southern Spain, analyzed sperm from hundreds of men aged between 18 and 22 and found those whose diet consisted more of junk food had lower quality sperm than those with a healthier diet.
The men were all assessed to ensure they were in good health and had no other issues that might effect their fertility and the sperm of those with "junk" diets seemed less likely to survive inside the womb so they could fertilize the egg and this was even the case if the men were at a balanced weight and took regular exercise.
Japanese scientists looking for similar traits focused more around exercise, showed that of the 215 men they studied those who took moderate exercise, even just brisk walking, had sperm with better swimming abilities than those who were less active.
