Modification of Sperm Motility and Its Storage Shelf Time

摘要

The invention relates to a composition for increasing sperm motility at low metal ion concentration and/or decreasing sperm motility at high metal ion concentration, wherein said composition comprises one or more metal ion selected from Co²⁺ and Ni²⁺ or compounds thereof as an active ingredient either alone or in combination with a physiologically acceptable carrier and optionally auxiliary ingredients.;The invention includes the use of the above metal ions or compounds thereof for the preparation of a composition for increasing sperm motility in low concentration and decreasing sperm motility in high concentration, and the use of such compositions.
