Eating cheese may harm man’s fertility

Young men who eat more than three slices of cheese a day may be risking their chances of becoming fathers, a new Harvard study has claimed.

Researchers discovered that even small amounts of full-fat dairy food can impair fertility in men. They found that men who eat even three portions of cheese a day had poorer quality sperm compared to others, the Daily Mail reported.

A portion includes 28 gm of cheese, a teaspoon of cream, a scoop of ice cream or glass of full-fat milk.

Researchers believe that female hormones that occur naturally in milk may be interfering with men's ability to reproduce. Scientist from the Harvard School of Public Health in the US compared the diets of 189 men aged 19 to 25, all very fit and did at least one and a half hour’s exercise a week.

Researchers also looked at their sperm quality, including how fast it travelled and its shape.
