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.

摘要： The present invention addresses the problem of developing a simple sperm inspection method and device for reflecting fertility. In the present invention, a simple sperm inspection method and device having a high correlation with fertility can be provided by suspending a sperm population in an inspection liquid and measuring a quality indicator value for each sperm, stratifying the sperm population on the basis of the sperm quality indicator value, and evaluating the quality of the sperm on the basis of the quality indicator value of one or a plurality of groups in the stratified population. This standard can predict fertility with higher precision through use of a graph in which the quality indicator values for individual sperm of the sperm population are arranged in sequence. Sperm motility is preferably used as a sperm quality indicator.
