Blue Zone regions identify demographic areas of the world where people have long life
spans. This study was conducted in a Blue Zone region where vegetarians consume 3.5
servings of meat substitutes per week. There is a paucity of information on the association
between vegetarian diet and male fertility. The premise was that semen parameters
were affected by diet. The objective was to compare sperm characteristics of male
infertility patients on vegetarian and non-vegetarian diets.
