Effect of transportation in vapour nitrogen on viability of bovine oocyte
Transporting vitrified oocytes using nitrogen vapour shipment between different places at a long distance is a common practice. However, achieving high viability of bovine oocytes during vapour shipping is a technique that has not been fully studied yet. In this study, the objectives were 1) to dete...
