Normal sperm quality despite partial deletion of sY84 in the AZFa region: A case report

The complete absence of the azoospermia factor A (AZFa) region typically results in nonobstructive azoospermia. Partial deletions of the AZFa region are particularly noteworthy due to the limited and enigmatic reports of partial deletions in the AZFa region. Here, we present a rare case report of partial deletion of sY84 in the AZFa region but exhibiting normal sperm quality. The aim of this case report is to gain a deeper insight into the impact of AZFa region deletion on male fertility and to guide future clinical decisions and treatment strategies.
