The aim of this study was to determine the patterns of Y chromosome microdeletions among infertile Mongolian men.Methods: A descriptive study was performed on 75 infertile men from February 2017 to December 2018. Y chromosome microdeletions were identified by polymerase chain reaction. Semen parameters, hormonal levels, and testis biopsy samples were examined.Results: Among 75 infertile men, two cases of Y chromosome microdeletions were identified. The first case had an AZFa complete deletion and the other had an AZFc partial deletion. This study found that the proportion of Y chromosome microdeletions among infertile Mongolian men was 2.66%.Conclusion: The findings can be applied to in vitro fertilization and assisted reproductive technology, and our results will help clinicians improve treatment management for infertile Mongolian couples.<\/jats:p>","DOI":"10.5653\/cerm.2021.05099","type":"journal-article","created":{"date-parts":[[2022,4,8]],"date-time":"2022-04-08T07:30:10Z","timestamp":1649403010000},"page":"101-109","update-policy":"https:\/\/doi.org\/10.5653\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Prevalence
