#6. Underwear for dogs
A Cairo University wanted to test how undergarments could affect the sperm production. To perform such tests they used dogs which were dressed with a cotton and polyester underwear. Another group of dogs were left as the control and the experiments went on for 3 months in which regular tests were done on sperm production. There were no big changes in sperm production although dogs that wore polyester underwear showed some small decline in sperm production.
