Information and data from eligible publications were searched and selected from the PubMed and Medline e-library from 2010 to 2020 by using 8 main keywords. The results showed that the prevalence of CAVD was approximately 0.1% in male and about 80% of congenital bilateral absences of the vas deferens (CABVD) patients had the CFTR mutation. These mutations were recessive gene abnormalities on the long arm of chromosome 7. Besides the mutation, recent researches showed the mutation of the ADGRG2 gene on X chromosome also led to CBAVD. It was approximately 10 - 20% of CBAVD and 60 - 70% of the congenital unilateral absence of the vas deferens (CUAVD) that was still not diagnosed genetically. In conclusion, the genetic consultation is necessary for CAVD patients before deciding to have a baby</span> </p>}, number={9}, journal={Tạp chí Y học Dự phòng}, author={Anh, Dang Tuan and Anh, Cao Tuan and Hoang, Nguyen Huy and Len, Bui Thi and Truong, Dang Tien and Hoang, Le and Dung, Tham Chi}, year={2021}, month={tháng 4}, pages={59–67} }
