Bacon and other processed meats decrease the sperm count whereas fish improves the sperm count, says study.

The findings showed that regular processed meat-eating males had radically lower amounts of normal sperm, as compared to those who ate less of bacon, sausages, hamburgers and ham.
Moreover, men who ate a portion of white fish every other day had better sperm count than those who ate foods such as cod more rarely.
Dr Myriam Afeiche, from the Department of Nutrition at Harvard School of Public Health, said that their study showed that processed meat intake was associated with lower semen quality and fish was to higher semen quality.
