Objective: Genetic factors, including Y chromosome microdeletions, are responsible for about 10% of male infertility cases and are particularly associated with azoospermia or severe oligozoospermia. In our study, it was aimed to determine the frequency of Y chromosome microdeletions in the Thrace region and to provide information about the heterogeneous phenotype in infertile male patients with AZF microdeletion. Material and Method: Chromosome analysis and Y chromosome microdeletion analysis were performed on 446 male patients with non-obstructive azoospermia or oligozoospermia, who applied to the Trakya University Hospital Medical Genetics Department Genetic Diseases Diagnosis Center clinic between the years 2011-2019. Results: Y chromosome microdeletion was detected in 19 (4.26%) of 446 cases. Structural chromosomal anomalies were accompanied in 5 of 19 cases with Y chromosome microdeletions. Three hundred fifty-two cases had no Y chromosome microdeletion, 35 (9.94%) of these cases had Klinefelter syndrome, 1 (0.28%) case had Klinefelter syndrome low grade mosaicism, 3 (0.85%) cases had Robertsonian translocation carriage, and 1 (0.28%) had Reciprocal translocation carriage. Conclusion: Y chromosome microdeletion screening in non-obstructive azoospermic or oligosoospermic infertile male patients has prognostic value and affects clinical prognosis. The results of our study support the proposal to perform Y chromosome microdeletion analysis before microTESE in azoospermic or oli gosoospermic infertile male patients as reported in the literature.
