Objective: To detection of microdeletions of Y chromosome and study the frequency of microdeletions in infertile men with non-obstructive azoospermia or severe oligozoospermia(Middle Euphrates center)in Iraq population. Material and methods: 153 males were included in the study, the casesweredivided into groups according to the infertility etiology and semen analysis according to Word health organization, the frequencies and the characteristicsof Y chromosome microdeletions were investigated in groups. Multiplex PCR was applied to detect the microdeletions. Results:Y chromosome microdeletion was detected in 42 (40.7%) of 153 cases ,Microdeletions in azoospermia showed more frequently detected 28 (52.8%), followed by severe oligospermia 14 (28 %),Microdeletions in the AZFc region were the most common 12 (22.64%), followed by AZFb 11(20.75%) and AZFa 5(9.43%) in azoospermia compared to severe oligospermisAZFc 6 (12%) AZFb 4 (8 %) and AZFa 4 (8%). Conclusion: Y chromosome microdeletions were detected quite frequently in certain infertility subgroups. Therefore, detailed evaluation of an infertile man by physical examination, semen analysis, hormonal evaluationsand when required, karyotype analysis may predict the patients for whom Y chromosome microdeletionanalysis is necessary and also prevent cost increases. Recommendation: This study emphasizes that analysis of microdeletions should be carried out for all patients with idiopathic azoospermia and severe oligospermia who are candidates for intracytoplasmic sperm injection

Objective: Advances in the science of genetics and the development of assisted reproductive techniques focus on the genetic causes of infertility. The aim of this research is to reveal genetic abnormalities in terms of sex chromosome aneuploidy and Y chromosome microdeletions. Material and Methods: A total of 350 patients with azoospermia or severe oligozoospermia were selected. After general examination of the patients and laboratory investigations were performed, cartoypes and Y chromosome microdeletions were examined. Results: A total of 225 infertile men with non-obstructive azoospermia (NOA) and 125 infertile men with oligozoospermia were enrolled into the study. The overall cytogenetic anomaly rate was 16%. Chromosomal changes were detected in 32 of 350 (9.1%) cases. The most common genetic anomaly was 47, XXY (Klinefelter syndrome) and the incidence was 11.5% in NOA group. This rate was 3.2% in oligozoospermia group. Y chromosome microdeletions were detected in 24 (6.8%) patients and similarly, it was observed more frequently in the NOA group than in the oligozoospermia group. Conclusion: The incidence of genetic causes have been increasing with the severity of infertility. As a result, genetic screening and appropriate genetic counseling are needed before the use of assisted reproductive techniques.

Abstract Backgound: Y chromosome microdeletions are the second most common genetic causes in male infertility. The aim of the present study was to reveal the patterns of Y chromosome microdeletions among Mongolian infertile men. Method: A descriptive study was performed to 75 infertile men during February 2017 to December 2018. Y chromosome microdeletions were identified by PCR. Semen parameters, hormonal levels, testis biopsy were determined. All collected data were evaluated with Statistical Package for Social Sciences (SPSS, version 22.0).Results: Among 75 infertile men, 2 cases of Y chromosome microdeletions were determined (2.66%). The first case had AZFa complete deletion and the other one had AZFc partial deletion. The azoospermia patient with AZFa complete deletion had Sertoli cell only syndrome in the testis biopsy, FSH 58.0 mIU/ml and LH 12.0 mIU/ml. The azoospermia patient with AZFc partial deletion showed FSH 23.85 mIU/ml and LH 13.01 mIU/ml. Serum FSH level was significantly higher in the Y chromosome microdeletion patients (p value 0.016). Conclusion: This study determined Y chromosome microdeletion among Mongolian infertile men to be at 2.66%. Our results showed FSH level is the best predictor of a successful TESE. However, best cut off value for FSH was 9.69 mIU/ml with a sensitivity and specificity 85.6% and 83.3% respectively. There is a possibility that sperm retrieval will be difficult from the TESE since the testicular tissue is severely damaged. The findings can be applied to IVF and Assisted Reproductive Techonology, and our results will help clinicians improve treatment management for Mongolian infertile couples.
