Molecular study on Y chromosome microdeletions in Egyptian males with idiopathic infertility.

Aim: To determine the frequency of genetic deletions within the azoospermia factors in Egyptian infertile males.

Methods: The Yq microdeletions in 33 infertile males with undetectable chromosomal anomalies were examined by mutiplex polymerase chain reaction (PCR). Deletions were confirmed using single PCR amplifications.
