Routine screening of semen found 18 azoospermia and 20 oligospermia patients (48.72%). Three pa- tients with 47, XXY, two with 46,XX(SRY+)and one with AZF c microdeletion were detected using QF-PCR technique which were verified by chromosome G-band and PCR. This study suggests that QF-PCR is a comprehensive, rapid and reliable method for detecting abnormal chromosomal regions and microstruc
