The link between a healthy diet and good sperm quality has been proven

The highest sperm concentration was recorded when following a vegetarian and rational diet. When choosing a Western diet, there was a 20% increase in the likelihood of producing poor quality sperm.

Danish scientists have found that with a healthy diet, men have better sperm quality and a higher total sperm count. The research results are published in the JAMA Network Open.

The study involved 2935 young Danes with an average age of 19 years. Based on the data obtained, scientists have identified four types of diets:

Western - the predominance of potatoes, red and processed meat, snacks, refined grain products, sugary drinks and sweets in the diet;

Rational - fish, chicken, fruits, vegetables occupied an important place in it;

· Sandwich - cold processed meat with whole grain bread, mayonnaise, spices, cold fish and dairy products;

· Vegetarian.

The researchers found that the amount of carbohydrates was similar across all groups, but the levels of fiber, total sugar, and added sugar intake varied significantly. For example, the Western diet had more added sugar and less fiber, the rational diet had less added sugar, the sandwich diet had more fiber, and the vegetarian diet had more added sugar.

Overall fat intake was also similar, but the balanced diet contained more long-chain omega-3 fatty acids, mainly due to fish.

Overall, 17% of participants had sperm counts below the lower limit of normal. The highest sperm counts were found in those who ate a rational diet (on average - 167 million), followed by supporters of the vegetarian (151 million), sandwich (146 million), and Western (122 million) diets.

The highest sperm concentration was recorded when following a vegetarian and rational diet. Supporters of a rational diet have a higher quality of sperm, a sandwich diet has a higher number of motile sperm, and a vegetarian diet has a higher percentage of normal sperm.

When choosing a Western diet, there was a 20% increase in the likelihood of producing poor quality sperm and an increased risk of decreased sperm production.

"If the associations reflect causality, then adherence to a Western diet can lead to a combined primary and secondary endocrine decline in spermatogenesis," the researchers noted.
