The present study to showed the relationship between microdeletion and IVF technique, then early detection of Y chromosome microdeletion is auxiliary to venereal treatment, particularly in those young patients with AZFc deletion. The study was used 65 patients, males (oligozoospermia ) and ten normal males, as control. DNA was recovered and treated, which was used for Y (CMD) through PCR SYBR Green real-time PCR for the amplification of three loci AZFa, AZFb, and AZFc regions. Our results showed only six samples (9 %) of single micro-deletions in the Y chromosome. Finally, the early diagnosis is very important for oligozoospermia patients whose will undergo the IVF technique. Kew word: Y chromosome, IVF technique, SYBER Green, Oligozoospermia.

According to published research, the prevalence of Y microdeletion in infertile males is roughly 7 %, with a range of 1-35 %. (1,2). From proximal to distal Yq, the long arm of the Y chromosome was found to include three AZF regions, namely AZFa, AZFb, and AZFc (3). The Azoospermia Factor was considered as the second genetic reason for the spermatogenic failure of infertile males, where treatment of that infertile individuals' which causes in regions that represent AZFa, AZFb, and AZFc (4).In situations with substantially impaired spermatogenesis, a Y chromosomal microdeletion test is recommended. Improvements in molecular biology methods have made regular diagnosis more accessible. However, not all IVF clinics detect Y chromosome microdeletions (5).The "Azoospermia Factor" (AZFa, AZFb, and AZFc) regions are all linked to
