Chromosomal Abnormalities In Sperm Higher After Vasectomy Reversal
Vasectomy Reversal and Abnormalities in Sperm
Men who have had a vasectomy reversed have a very much greater rate of chromosomal abnormalities in their sperm than do normal fertile men, a scientist told the 22nd annual conference of the European Society of Human Reproduction and Embryology in Prague, Czech Republic on Wednesday 21 June 2006. Professor Nares Sukchareon, of the Department of Obstetrics and Gynaecology, Chulalongkorn University, Bangkok, Thailand, said that doctors needed to be aware of this problem and monitor carefully children born as a result, particularly if ART was involved.
Professor Sukchareon and his team had been studying men with obstructive azoospermia, a condition where sperm are created but cannot be mixed with the ejaculatory fluid due to a physical obstruction (such as a vasectomy). He found that they had high rates of chromosomal aneuploidy (where an abnormal number of specific chromosomes or chromosome sets exist within the nucleus of the cell) and diploidy (containing two sets of chromosomes
