Scientists have proven that fast food causes infertility

Scientists from Harvard University foundThat passion for fast food in adolescence can lead to infertility. If your diet is common pizza, chips and red meat, it is worth pondering.

The researchers examined the medical records of about three thousand Danish conscripts, whose average age was 19 years. Each of them had to be pointed out as he usually eats. All the young men had four options:

1. foods high in fat and processed foods.
2. Traditional vegetarian.
3. chicken, fish, vegetables and fruits.
4. processed meats, whole grains, cold water fish and dairy products.

The scientists found that those who prefer the first option, fared worst of all. They had the lowest concentration, volume and motility sperm. Moreover, supporters of such a diet have been depleted Sertoli cells - the ones that are responsible for sperm production.

According to the researchers, a diet change can increase sperm volume within three months. But the damage to Sertoli cells irreversibly.
