Cheese May Decrease Male Fertility

eating cheese decrease male fertilityAs a dairy product, cheese is a good source of calcium, which is needed by the body to maintain strong bones and teeth. But a new study suggests that too much consumption of cheese may decrease fertility in men.

According to a study conducted by researchers from Harvard School of Public Health in the US, young men who eat more than three slices of cheese a day may be risking their ability to reproduce.

In the study, the researchers compared the diets of 189 men aged 19 to 25 who were fit and did exercise at least one and a half hour’s a week.

Each of the participants filled out a questionnaire answering how often they ate dairy products, fruit, meat and other types of food during a typical week.

The researchers also looked at their sperm, including how fast it traveled and its shape. They found that the sperm of men who ate more than three portions of full-fat dairy food per day were 25 percent lower quality than those who had less.

A portion included an ounce of cheese (28g), a glass of full-fat milk, a teaspoon of cream, or a scoop of ice cream.

“While it has been suggested that full-fat dairy products may negatively affect semen quality, very few studies have actually examined this question directly,” said Myriam Afeiche, who led the study.

Dr. Allan Pacey, fertility expert at the University of Sheffield and Chairman of the British Fertility Society advised men not to give up on dairy purely on the basis of this study. He pointed out that although male fertility had gone down, they won’t have any problems conceiving.

“Although it goes down, it doesn’t go into the red. A change of that magnitude for a man in a fertility clinic, we wouldn’t worry about that,” Pacey said, as reported in the dailymail.

“What I would say about diets is we don’t understand it well enough. I wouldn’t want to scare men out of drinking milk,” he added.
