Scientists have found that sperm from diabetic men have greater levels of DNA damage than sperm from men who do not have the disease. They warn that such DNA damage might affect a man? fertility. In the first study [1] to compare the quality of DNA in sperm from diabetic and non-diabetic men, the researchers from Belfast, Northern Ireland showed that the DNA in the nuclei of the sperm cells had greater levels of fragmentation in diabetic men (52%, versus 32% in non-diabetic men), and that there were more deletions of DNA in the tiny, energy-generating structures in the cells called mitochondria (4 versus 3).>>> Discuss This Story
