Normal fertility with deletion of sY84 and sY86 in AZFa region

Entire deletion of the azoospermia factor a (AZFa) region commonly results in non‐obstructive‐azoospermia (NOA). Although sY84 and sY86 are recommended as the first choice of sequence‐tagged sites (STSs) primers in AZFa region, and their deletions suggest a very high probability of complete deletion of AZFa, extension analysis is now compulsory to identify the deletion pattern.
