association study between longitudinal changes of leukocyte telomere and the risk of azoospermia in a population of iranian infertile men

ABSTRACT

Background: Telomeres are evolutionary, specialized terminal structures at the ends of eukaryotic chromosomes containing TTAGGG repeats in human. Several human diseases have been known to be associated with dramatic changes in telomere length. The aim of the present study was to assess the correlation between the relative leukocyte telomere length [LTL] and infertility in a group of Iranian azoospermic males
