Recently, there has been increased emphasis on the evaluation of sperm quality. Much of this has been due a growing realisation that a sperm or semen test is actually of limited value. Sperm, in essence, act as little more than vehicles by which DNA is carried from the male to the female egg.
Only very few make it to their goal, and along the way a potentially damaging process is undertaken, where the protein blocks designed to protect the sperm can very often fail, leaving DNA susceptible to damage and at risk of becoming fragmented.
