With each passing year, the world's obese population is increasing. A bad diet, no time to eat, with excessive caloric intake, along with a lack of physical exercise make a large part of people overweight.
In the case of men, weight gain has a high implication in their fertility, as it can affect the sperm production in the testicles. This can lead to alterations in sperm concentration and mobility, as well as an increase in sperm DNA fragmentation. On the other hand, obesity also implies a decrease in the level of testosterone and a greater probability of suffering erectile dysfunction.
