Food affects the male seed in a few days

Nutrition has rapid effects on the quality of the male semen: it is enough to eat badly for a few days to see the 'health' of the sperm diminish.
This is the conclusion of a study by the University of Linköping in Sweden published in the journal PLOS Biology, in which young people consumed a sugar-rich diet for a week and the researchers observed immediate effects on the quality of their seed.
The study is based on similar research on mice and fruit flies: the animals that ate a lot of sugar and immediately mated became the father of overweight puppies. Hence the idea of ​​seeing whether food also has immediate effects on sperm in men. Experts involved a group of healthy, non-smoking young males who consumed all meals in the laboratory for two weeks; the first week a healthy diet and the second a diet with a huge quantity of sugars, equal to 450 grams of jam per day or 3 and a half liters of drinks per day. The quality of their sperm was measured at the beginning of the study and then again after the first and second weeks.
At the beginning, a part of the sample started with reduced sperm quality (a percentage similar to the percentage of males with low sperm quality present in the general population). After the first week of a healthy diet all males had better quality sperm than at the beginning of the study; after the second week, however, all had a reduced sperm quality.
"We have seen that diet affects sperm motility and we can link these changes to the appearance of specific molecules within them - says Anita Öst, coordinator of the work. Our study has highlighted the rapid effects of the diet," he adds. "The study shows that sperm motility can be changed within a short period - he concludes - and appears to be intimately related to diet. This has important clinical implications", for example in assisted fertilization. (ANSA).
