In this study, the prevalence of CFTR mutations and variants in men with azoospermia without CBAVD/CUAVD (7.5%) and of CFTR exon mutations alone (4.2%, Table 1) only slightly exceeds the expected prevalence, since the prevalence of CFTR exon mutations in the general population is 3%‐4%.9 Here, CFTR is linked to Azoospermia.
