Bacon can harm a man's fertility - Half portion a day of processed meat 'significantly harms sperm quality' - 

Men who eat just one rasher of bacon a day could be reducing their chances of becoming fathers.
Half a portion of processed meat such as a rasher or a small sausage can significantly harm sperm quality, scientists believe.
Those who want to boost the odds of having a child should eat fish instead – with species such as cod or halibut appearing to have a particularly dramatic effect on fertility.

The findings add to the growing evidence that a couple’s chances of having children is strongly governed by their lifestyle – with smoking, alcohol and stress having a detrimental effect and exercise and diet enhancing it.
Experts are still unclear why certain foods can harm or promote fertility, but red meat is thought to contain high levels of pesticides and other substances that can interfere with hormones. White fish is rich in zinc, which is believed  to boost fertility.

In a study to be presented this week at a meeting of the American Society for Reproductive Medicine in Boston, Harvard University researchers compared the eating habits of 156 men undergoing IVF treatment with their partners. 
They were each questioned how often they ate a range of foods including processed meat, white meat, red meat, white fish and tuna or salmon. Men who consumed just half a portion of processed meat a day had just 5.5 per cent ‘normal’ shaped sperm cells, compared to 7.2 per cent of those who ate less.
Men who had dishes containing white fish at least every other day – or half a portion daily – had far better sperm quality than those who ate it rarely.
