Popis: The C57BL/6 mouse is commonly used to produce transgenic and knockout strains for biomedical research. However, the motility and fertility of its sperm decrease markedly with freezing. Short-term preservation of sperm without freezing can avoid this. Furthermore, such samples can be transported safety without the special skills or equipment needed for the transportation of live animals or frozen products. We evaluated the motility and fertility of sperm collected from cauda epididymides after preservation or transportation at 4 degrees C. Oocytes with the zona pellucida subjected to laser-microdissection were used to assist fertilization in vitro. Although the motility of sperm gradually decreased with storage (P
