Additional Information

To detect Y chromosome microdeletions associated with oligospermia and azoospermia. About 15-20% of azoospermic men and about 10% of severely oligospermic men present with microdeletions of Yq. This test targets 20 genetic loci, including those recommended by the European Quality Monitoring Network Group (Int J Andr 22:292-299 (1999)).
