Fragmentation of the DNA of the sperm

In addition, they have used a problem-based approach to illustrate the clinical utility of SDF 1. Apart from the use of antioxidants, there is suggestion of using testicular sperm instead of the epididymal ejaculate for ICSI. Some doctors also recommend drawing sperm directly from the testicle with a needle, rather than getting it the old-fashioned way. If the DNA is intact then no dye will attach to the sperm.

Sperm DNA Fragmentation | Fertility & IVF investigations & diagnosis

In conclusion, we agree with the authors that the use of SDF testing, along with conventional semen analysis, could provide a better knowledge of male fertility potential. Men with otherwise normal semen analyses can have a high degree of DNA damage and men with what was called very poor sperm quality can have very little DNA damage. The question of how much impact DNA damage has on human fertility has generally been directed towards assisted reproductive techniques ART , principally intracytoplasmic sperm injection ICSI in which a single sperm is manually selected and injected into the egg. As analysis techniques improve and more refined studies are undertaken we may see a much larger role for sperm DNA fragmentation testing in the future, but it cannot be regarded as part of the routine semen assessment at the current time. Then, using a procedure called flow cytometry, the sperm that took up lots of dye the sperm with fragmented DNA can be differentiated form the sperm that took up only a little dye sperm with normal DNA. What surgical techniques does Dr. The various methods are broadly in agreement when assessing any particular sample, though the nature and severity of a specific DNA injury is not revealed.
