چکیده

Background and aim: asthenozoospermia is an important cause of male infertility. mutations in sperm mtdna result in either functionless or malfunctioning proteins, subsequently affecting sperm motility leading to asthenozoospermia. the purpose of this was to investigate sperm mtdna 4977 bp deletion in infertile men with low sperm motility compared to healthy subjects with high sperm motility.methods: semen samples of 64 asthenozoospermic infertiles and 64 controls from northern iran were collected. after extraction of spermatozoa total dna, primer-shift pcr was performed.results: the deletion was observed in 85.93 % of patients with asthenozoospermia compared with 10.9 % in controls [or = 49.7619, 95 % confidence interval = 17.3278-142.9057, p = 0.0001].conclusion: it is concluded that there is a strong association between sperm mtdna 4977 bp deletion and asthenozoospermia-induced infertility in the population examined. large-scale mtdna deletions in spermatozoa may induce bioenergetic disorders.
