Evaluation having AZF microdeletions was carried out in the brand new ninety NOA dudes which have regular karyotype. With the EAA/EMQN standards, AZF region microdeletions with the Y chromosome were included in patients with a regularity regarding 2.22%. The fresh new were not successful amplification from sY254 and you can sY255 indicators suggests a complete deletion on the AZF sub-region (Figure a dozen).
