Upstream type high-activity sperm optimization equipment and optimization method

The invention discloses upstream type high-activity sperm optimization equipment and optimization method, and belongs to the technical field of assisted reproduction, the optimization equipment is formed by combining an upper half culture solution cabin part and a lower half centrifugal tube part, and the upper half culture solution cabin part and the lower half centrifugal tube part are separated by a vertically-through microporous filter membrane; the upper half culture solution cabin part adopts a filter head with a cabin separation type design, so that a sample inlet is separated from a culture solution main cabin, meanwhile, an internal separation small plate is subjected to 45-degree inclination treatment, a recess is reserved in the top of the lower half centrifugal tube part for accommodating a filter membrane, and the filter membrane is physically fixed through clamping of a buckle; according to the optimization method, high-activity sperms are screened through optimization equipment and upstream cha
