Background: The microdeletion events that occur in the Y chromosome-azoospermia factor () region may lead to dyszoospermia. Also, the deleted azoospermia () gene on AZFc and autosomal deleted azoospermia like gene () are suggested to represent impairment, so it is interesting to determine the independency pattern of the region and gene in azoospermic patients.
Aim: To study the molecular characterization of and in 64 idiopathic non-obstructed azoospermia patients and 30 sexually reproductive men.
