Another study by Sharma et al. (11) analyzing the frequency of CFTR mutations in infertile Indian males with non-obstructive azoospermia (n=60) and spermatogenic failure (n=150), showed that ΔF508 mutation was observed in 3.6% of patients with non-obstructive azoospermia. The gene discussed is CFTR; the disease is Infertility.
