[USA], Mar 17 (ANI): Scientists have found that the DNA of sperm taken from the testicles of infertile men was as good as that of ejaculated sperm of fertile men. The research may explain a major cause of male infertility and open up the possibility of using sperm taken directly from the testicles to overcome infertility among males. Sperm DNA damage is known to be a major cause of male infertility and reduces a couple’s chances of having a family. ” Professor Sheena Lewis, Emeritus Professor Queens University, Belfast and founder of ExamenLab, said: “What this means is that the DNA in sperm from the testicles of infertile men are better quality than sperm from their ejaculates. As DNA integrity is believed to play a role in fertilization rates in assisted reproduction, these results may assist in the decision-making whether or not to resort to testicular biopsy/testicular sperm aspiration rather than using ejaculated sperm to enhance success rates of assisted fertilization in infertile men with signs of DNA damage.
