The Sperm Chromatin Structure Assay (SCSA) is a new diagnostic tool that can This test uses special stains and complex instrumentation (flow cytometer).

Description:Several studies had implied that the conventional sperm parameters count, motility and morphology as measured on a routine semen analysis had no bearing on success when ICSI was used. Some couples then went on to use both egg donors and surrogates thinking it was both an egg quality and implantation issue, again without success. About a year and a half ago a relatively new concept was introduced to clinical practice; sperm quality was dependent on the amount of damage to the sperm DNA or DNA fragmentation. Simply put, DNA is arranged in a double helix or ladder configuration with side rails and rungs. What has recently been shown in several studies is very interesting and in some ways unexpected. Sperm DNA fragmentation has little or nothing to do with the parameters that we measure on the routine semen analysis.
