Microdeletion of Y Chromosome

Genetic testing services

It has been shown that men with non-obstructive ductile infertility (vas deferens are present and not obstructed) were more frequently carriers of microdeletions (small deletions) in their DNA, targeted regions associated with sperm production. Three targeted regions are commonly called AZFa, AZFb and AZFc, they are directly involved in the production of spermatozoa.Reference: ( Mol Hum Reprod.4: 739-744).
