We assessed the frequency of CFTR mutations in groups with varying degrees of sub-fertility and compared these groups to a fertile male group with proven paternity. Screening for CFTR mutations should be routine for all azoospermic males, irrespective of obstructive or non-obstructive etiology, prior to proposing ICSI treatment. CFTR testing has no value in the investigation of non-azoospermic infertile males. Copyright © 2010 American Society for Reproductive Medicine, Published by Elsevier Inc.
