| Outline of Final Research Achievements |
The aim of the present study was to develop a new method to evaluate sperm molecular characteristics for identifying AI-subfertile males of livestock. In this study, we succeeded in the development of the method to evaluate molecular characteristics of bull (Japanese Black bull) cryopreserved and freshly ejaculated spermatozoa by the observation of acrosomal tyrosine-phosphorylated proteins. Moreover, we also showed that outcomes of AI and in vitro fertilization can be predicted by this evaluation for the spermatozoa.
