Zoos are not only entertainment centers, but also play an important role in the maintenance of the species.
At a Dutch zoo, Thor, the male lion, did a very good job of maintaining the species because he also had five offspring last year. As a breeding animal, not only proved, but also fulfilled the plan, so the management of the zoo decided to render the lion infertile.
Thoron vasectomy was performed in order to maintain genetic diversity. In the case of vesectomy, there is no decrease in hormone levels, i.e. as a dominant male it will stand in the same way, only its offspring will not be born.
