A technique for selecting and concentrating the motile sperm from semen in oligozoospermia.
Using an albumen-filled column, it was possible to separate highly motile sperm from autoagglutinated, dead and immotile sperm, as well as from other seminal debris. Motility was increased from a mean of 45.4 to 74.3% (P less than 0.001), although the sperm density fell from a mean of 28.2 million per ml to 9.7 million per ml (P less than 0.001). When these selected highly concentional AlH had been repeatedly tried without success, 3 pregnancies were achieved in 18 women (16.7%).
