Abstract
Human sperm progressively motile and free of seminal debris can routinely be isolated, during a 1.5 hour process, from semen of normal and subfertile men. Serum albumin, in a vertical column, acts to filter sperm based on their swimming abilities of forward progression. The isolated sperm constitute a population that can be inseminated as an aid to male subfertility or, to enhance the chances of sperm survival upon deep-freeze preservation. The latter use resulted in twice the survival rate, based on sperm motility, or random populations of control sperm.Keywords
