8 % of male infertility due to genetic deletions in Y chromosome

A recent study found that two spontaneously recurring deletions along a complex region of the Y chromosome are responsible for around 8 % of cases of failed sperm production.

Although research was already available which established the relation b/w AZFc (Azoospermia Factor c) and Severe Spermatogenic Failure (SSF), the current research determines the prevalence of these deletion in general population.
