Short video description
Your Exact sperm DNA test results provide important information about your reproductive health which can help you make informed decisions about lifestyle changes or treatments to improve your fertility. Exact tests measure sperm DNA damage which could be a significant factor affecting your fertility. The Exact test result shows three different indicators of DNA damage fragmentation compared against a fertile reference range. Most sperm from fertile men have low damage. Infertile men have more sperm with moderate or high damage. The average amount of DNA damage per sperm in your sample.

Sperm chromatin structure assay (SCSA): a tool in diagnosis and treatment of infertility

Sperm DNA fragmentation is being increasingly recognized as an important cause of infertility. The SCD test is based on the principle that sperm with fragmented DNA fail to produce the characteristic halo of dispersed DNA loops that is observed in sperm with non-fragmented DNA, following acid denaturation and removal of nuclear proteins. Sperm suspensions either prepared from semen or isolated from semen by gradient centrifugation were embedded in an agarose microgel on slides and treated with 0. SCD test values were significantly higher in patients being screened for infertility than in normozoospermic sperm donors who had participated in a donor insemination program. In conclusion, the SCD test is a simple, accurate, highly reproducible, and inexpensive method for the analysis of sperm DNA fragmentation in semen and processed sperm. Therefore, the SCD test could potentially be used as a routine test for the screening of sperm DNA fragmentation in the andrology laboratory. Abstract Sperm DNA fragmentation is being increasingly recognized as an important cause of infertility.

Sperm DNA Fragmentation Test

Sperm DNA fragmentation testing is an opportunity to evaluate male fertility beyond semen analysis for those undergoing infertility treatments. Sperm carries DNA from the male testicles to the female egg. A very large amount of DNA is compacted into each tiny sperm, and the fragile DNA is tightly wrapped around protein structures, which help protect it. Together, the protein structures and DNA form chromatin.

For Shauna Harrison, her journey from only child to a sister with 29 siblings started with a revisit to her 23andme profile. Having known for more than a decade she was conceived by sperm donor, she took a test from the DNA service in to learn more about her family history. As a fitness trainer with a PhD in public health, she wanted to know more about her health history. When she changed her profile from anonymous to public, she discovered she had a half-sibling, sharing the same donor. That sibling was Stephen Bisordi, 40, who had started a Facebook group years before with three other siblings so they could all connect.
