Transmission electron microscope morphogram of progressive motile sperm cell fraction separated from teratozoospermic human semen.
Teratozoospermic semen specimens were separated, with the aid of a specially designed separation chamber, into an upper progressive motile sperm fraction and a lower fraction containing a high percentage of sperm cells of poor or no motility, and immature germinal cells. Analysis of the TEM morphograms of progressive motile cell fractions and original teratozoospermic semen revealed that 15 various malformations were improved significantly in the motile cell population due to the cell separation technique.
