Abstract |
Aim: To explore the possible effect of the deleted in azoospermia (DAZ) copy cluster deletion on spermatogenesis in the Chinese population, the deletion of the azoospermia factor c (AZFc) region was analyzed in 346 normozoospermic men.
Methods: Three DAZ single nucleotide variant loci and seven AZFc-specific sequence-tagged sites were examined with polymerase chain reaction (PCR)-restriction fragment length polymorphism and routine PCR.
Results: Five (1.4%) of the normozoospermic men were found to have deletion of gr/gr-DAZ1/DAZ2. None of the men were found to have b2/b4-entire DAZ deletion.
Conclusion: The presence of gr/gr-DAZ1 /DAZ2 deletion in five men with normozoospermia suggests that this deletion per se may not be sufficient for spermatogenic impairment in Chinese men.
Keywords: azoospermia factor c, deleted in azoospermia, gene deletion, normozoospermia
