Molecular basis of fertility variation in cryopreserved bull semen: Functional evaluation and expression analysis of IZUMO1, PLCζ, and CatSper genes
Semen cryopreservation serves as a pivotal biotechnological tool implemented in artificial insemination programs to accelerate genetic progress in cattle breeding. However, the freeze-thawing cycle can heavily compromise fertilization efficiency due to sublethal cellular, functional, and molecular injuries. This study...
