| 摘要 |
This invention addresses the problem of providing a sperm-motility enhancer—in particular, a forward-sperm-motility enhancer—for use on reduced-motility sperm in male infertility treatment. A gaseous sperm-motility enhancer comprising a gas that contains hydrogen molecules in the amount of at least 1% (v/v)—for example, a gas that contains hydrogen molecules in an amount between 45% and 55% (v/v), inclusive—or a liquid sperm-motility enhancer comprising a liquid such as normal saline, a nutrient broth, or a buffer solution containing hydrogen molecules in the amount of at least 1% of the saturation solubility thereof—for example, a liquid in which hydrogen molecules have been dissolved by means of bubbling—is prepared. The gaseous sperm-motility enhancer can enhance the motility of sperm by making hydrogen gas and either semen or a dilution thereof contact each other in a gaseous phase. The liquid sperm-motility enhancer can enhance the motility of sperm when used as a washing solution or diluent for semen. |
