The SCSA, or Sperm Chromatin Structure Assay, is a test for male infertility. It quickly and accurately identifies men who are less likely to achieve a full term pregnancy naturally or with ART. It does this by determining the percentage of sperm with high levels of DNA fragmentation, i.e. the DNA Fragmentation Index (% DFI) as well as the percent of sperm with abnormal proteins (%HDS) and morphology that may inhibit fertilization.
The test is based on well-established research and methods. Developed over the course of more than 20 years, the SCSA has been the subject of more than 125 articles published in peer-reviewed journals and periodicals.
