Paternal contribution to development: Sperm genetic damage and repair in fish
Scientists discover how 'companion' cells to sperm protect them from genetic damage
Curr Opin Obstet Gynecol. Apert syndrome is a serious disfiguring birth defect. Development of an image analysis system to monitor the retention of residual cytoplasm by human spermatozoa: Although the mechanisms by which sperm DNA integrity is assessed in these assays varies, most tests of sperm DNA integrity generally correlate well with each other. Sperm chromatin dispersion test The sperm chromatin dispersion SCD test is based on induced condensation which is directly linked with sperm DNA fragmentation [ 93 ]. Genetic damage can reduce the chances of a sperm fertilising an egg, or can lead to the formation of an embryo that fails to implant properly or is miscarried. Testicular stem cells undergo mitotic and then meiotic cell division over the course of about 70 days.

The dark and bright sides of reactive oxygen species on sperm function. Development of an image analysis system to monitor the retention of residual cytoplasm by human spermatozoa: Increasing evidence suggests that sperm DNA damage has a negative impact on male fertility potential [ 40 , 45 , 62 , — , , ]. Additionally, we investigated the influence of several common lifestyle factors on sperm DNA damage using questionnaire data. Prevalence of abnormal sperm DNA denaturation in fertile and infertile men.
