Composition for sperm treatment, sperm motility improving agent, sperm fertilizing capability retaining agent, sperm motility improving method, and sperm fertilizing capability retaining method

Abstract

The purpose of the present invention is to provide spermatozoa having high motility. The present invention is a composition for treating sperm that comprises a mesenchymal stem cell culture supernatant. The composition for spermatozoa treatment of the present invention is used as a sperm preparing solution, a sperm diluting solution, a sperm storage solution, an artificial insemination solution, an in vitro fertilization solution, a solution for improving sperm motility, or a solution for retaining sperm fertilizing capabilities. Furthermore, mesenchymal stem cells in the mesenchymal stem cell culture supernatant comprised in the composition for treating sperm are preferably derived from adipose tissue, derived from umbilical cord tissue, or derived from bone marrow tissue.
