Milk butter can help men avoid pregnancy?

A new study by experts from Harvard School of Public Health found that men who consumed 3 servings of dairy products every day had poorer sperm quality and were therefore reduced. fertility loss. So the new advice for the eyebrow is: instead of using a condom, try drinking a few cups of milk.

Although many reproductive health studies often focus on the effect of diet on the ability of women to conceive, the scientific community is increasingly concerned about the effects of diet and nutrition. men's lifestyle for their ability to produce healthy sperm.

The researchers found, eating / drinking more than 3 servings of dairy
Daily fat was reduced by 25% quality of sperm.

Researchers at Harvard University analyzed the diet of 200 healthy, fit men between the ages of 19 and 25 and participated in physical training for at least 1.5 hours per week. . These subjects then went to a multiple choice questionnaire to record how often they ate, drank dairy products, vegetables, meat and other foods. In it, 1 part of dairy food is calculated as the sum of 28g of cheese, 1 teaspoon of butter cream and 1 tablespoon of ice cream or with a cup of non-fat milk.

The team also analyzed the shape and speed of sperm produced by these men. As a result, men who consume more than 3 servings of whole-fat dairy daily have a 25% reduction in sperm quality compared to their peers who consume less milk.

Scientists believe that estrogen - the female hormonal hormone that is naturally present in cow's milk - is the "culprit" that reduces the quality of men's soldiers. The Daily Mail quoted the research team member Myriam Afeiche, who said: "This solidarity may be due to the high concentration of naturally occurring reproductive hormones in naturally occurring dairy products on the market. school ".

Ms. Afeiche also mentioned the possibility that residual pesticide chemicals, heavy metals, . found in dairy products can affect male fertility.

However, Allan Pacey, a reproductive health specialist at the University of Sheffield and president of the British Breeding Association, advises men not to stop eating dairy products because of the results of the study. Even when sperm quality and sperm production decline, he said, consumption of dairy products ultimately does not affect fertility.

Previous studies have linked fertility decline in men to excessive carbohydrate absorption and obesity.
