Semen Quality in Relation to Semen Preservation
Journal of Dairy Science, 1983 A goal of research in laboratory evaluation of semen has been ultimately to predict the fertility achievable with use of that semen. This would permit evaluation of the male and ejaculate. For artificial insemination, semen viability becomes a measure of man's interaction with that semen in an effort to preserve its functional life. Man's efficiency in
