For the food production, young bulls are castrated for the improvement of meat quality through the removal of male hormones. Importantly, these castrated testes are discarded because they are not suitable for food. Thus, over 99% of bull testes are “unused agricultural resources”, although they have a potential to produce numerous spermatozoa. If the method to produce spermatozoa in vitro from castrated testis are established, it will be an important agricultural technology for the future animal production. Additionally, although I am not expert of toxicology, I have received advice on what in vitro spermatogenesis using castrated bovine testes will be good model for the reproductive toxicity as an alternative method over animal experiment. In this meeting, I will show recent our study about bovine spermatogenesis and discuss its potential usefulness in the field of toxicology.
