Sperm viability and DNA fragmentation are independent parameters of sperm quality

Date: 9-15-2009

Gosalvez J. et al.  (2009  A dynamic assessment of sperm DNA fragmentation versus sperm viability in proven fertile human donors) Fertility and Sterility 92:1915-19.

“The rate of viability loss and the rate of increase of the frequency of sperm cells with fragmented DNA were determined at various times over 24 hrs after thawing samples from donors with proven fertility.  In the short term, dynamic dysfunction of membrane permeability does not result in DNA fragmentation and thus must be considered as independent parameters of sperm quality.”
