1. : a theory in geology: the lithosphere of the earth is divided into a small number of plates which float on and travel independently over the mantle and much of the earth's seismic activity occurs at the boundaries of these plates. 2.
Sperm DNA Fragmentation Test. The genetic integrity of the sperm is crucial for successful fertilization and normal embryo development. Sperm DNA fragmentation is a term used to denote when the genetic material within the sperm is abnormal, which in turn may lead to male subfertility and IVF failure.s a second generation sperm DNA test. It detects the sperm with DNA damage and also tells how much DNA damage each sperm have. A SpermComet test result of 45% means that there is an average of 45% damage in each sperm that was assessed.
It is likely that sperm DNA fragmentation levels are on the rise due to increased reproductive toxicants in our environment, says Donald P. Evenson, Ph.D., HCLD, president and director of SCSA Diagnostics.y husband is type 1 diabetic and we've been trying to conceive for over 2 years. Done all the typical sperm test, blood test and HSG and results are all normal. The doctor never mentioned that there could be Sperm DNA Fragmentation caused by his diabetes, and I don't think that was tested at all.
