Cryopreservation of Human Spermatozoa Decreases the Number of Motile Normal Spermatozoa, Induces Nuclear Vacuolization and Chromatin Decondensation

12 Nov 2012

Abstract excerpt

Even though cryopreservation of human spermatozoa is known to alter sperm motility and viability, it may also induce nuclear damages. The present study set out to determine whether or not cryopreservation alters motile sperm morphology under high magnification and/or is associated with chromatin decondensation. For 25 infertile men, we used high-magnification microscopy to determine the proportions of various...
