The aim was to determine the prevalence of compound genetic abnormalities in patients who are carriers of cystic fibrosis transmembrane regulator (CFTR) gene polymorphism and to compare our results with similar patients reported in the literature. One hundred and nine patients were identified to be carriers of CFTR gene polymorphism. Additional genetic testing for karyotype abnormalities or Y chromosome microdeletions (YMD) was performed. Three patients (2.75%) of 109 were identified to have compound genetic abnormalities. One patient had 5T/5T while the other had 6T/6T and the third had 9T/9T. The three patients had deletions of azoospermia factor regions (AZFa+b or AZFa+b+c). There were no karyotype abnormalities identified in our database. In the literature, four patients with compound CFTR mutations and YMD were identified, in three patients had karyotype abnormalities. In conclusion, compound genetic abnormalities in CFTR mutation patients can be a contributing factor when abnormal spermatogenesis is encountered.
