Ninety samples were harvested from 20 men with nonobstructive azoospermia and divided into two fractions; the first fraction was minced, and the second fraction was exposed to the freezing and crushing (FC) technique. The sperm recovery rate was found to be 21/30 (70%) in the FC fractions compared with 8/30 (26.6%) in the mincing fractions.
