New research has shed light on our understanding of male infertility and how we may better treat it in the near future. The research team led by Dr. Jonathan Ramsay , a consultant urologist at Imperial College Healthcare, London, took sperm directly from the testicles of 63 men who were infertile, and then compared these samples with ejaculated sperm from the same men. All of these men had experienced failed fertility treatments of intracytoplasmic sperm injections ICSI. Both the ejaculated and extracted testicular sperm from these men were examined for single and double DNA strand breaks.

Sperm DNA damage: clinical significance in the era of assisted reproduction

Try out PMC Labs and tell us what you think. Learn More. Evidence suggests that damage to human sperm DNA might adversely affect reproductive outcomes and that the spermatozoa of infertile men possess substantially more sperm DNA damage than do the spermatozoa of fertile men. This is particularly relevant in an era where advanced forms of assisted reproductive technologies are commonly used technologies that often bypass the barriers to natural selection , because there is some uncertainty regarding the safety of using DNA-damaged spermatozoa.
