摘要： Provided are a diluent and a sperm preservation method using the diluent. The diluent is useful in preservation of sperm with high fertility, and is capable of stably achieving quality control and improving quality of the sperm. Refrigerating or freezing sperm using the diluent for sperm, which includes an aqueous solution containing at least one oligosaccharide selected from the group consisting of a fructo-oligosaccharide, an isomalto-oligosaccharide, a gentio-oligosaccharide, and a galacto-oligosaccharide, can improve the quality of preserved sperm and provide sperm having high fertility, at a reduced cost.
