Higher frequency of Yq microdeletions in sperm DNA as compared to DNA isolated from blood.
AIM To determine if Yq microdeletion frequency and loci of deletion are similar in two tissues (blood and sperm) of different embryological origin. METHODS The present study included 52 infertile oligozoospermic cases. In each case, DNA was isolated from blood and sperms and polymerase chain reaction (PCR) microdeletion analysis was done from genomic DNA isolated from both the tissues. The PC...
متن کاملImpact of DNA Damage on the Frequency of Sperm Chromosomal Aneuploidy in Normal and Subfertile Men
Background: Various frequencies of sperm aneuploidy are reported in sperms of subfertile patients compared to normal individuals. Moreover, sperm DNA damage is shown to be associated with male infertility. In this study, the rate of DNA damage and frequencies of aneuploidy in sperms of subfertile patients was investigated. Methods: Semen samples were obtained from healthy normal and subfertile ...
متن کاملY chromosome microdeletions, sperm DNA fragmentation and sperm oxidative stress as causes of recurrent spontaneous abortion of unknown etiology.
BACKGROUND The aim of the present study was to evaluate the implication of male factor, in terms of sperm DNA oxidation and fragmentation, and Y chromosome microdeletions in recurrent spontaneous abortion (RSA) of unknown origin in a strictly selected cohort. METHODS A prospective cohort study was carried out in a private university-affiliated setting. Three groups, each comprised of 30 males...
متن کاملcan zeta sperm selection method, recover sperm with higher dna integrity compare to density gradient centrifugation?
background: sperm selection for icsi based on morphology and motility might not be relevant to chromatin integrity. thus sperm selection based on sperm characteristics has been suggested. objective: the aim of this study was to compare the efficiency of zeta method with routine density gradient centrifugation method (dgc) for the selection of sperm with higher dna integrity. materials and metho...
متن کاملHigher clusterin immunolabeling and sperm DNA damage levels in hypertensive men compared with controls.
BACKGROUND Clusterin, a heterodimeric glycoprotein found at several sites in the human male reproductive tract, could be a marker of morphologically abnormal spermatozoa, while TUNEL positivity indicates DNA fragmentation. Metabolic disorders such as diabetes mellitus and obesity may compromise sperm quality and fertility of men; however, little evidence specifically links hypertension with the...
