What is SAT test?
- The Sperm Aneuploidy Test (SAT) is a test to study the genetic factor of male infertility.
- It allows for the evaluation of the presence of an abnormal number of chromosomes (aneuploidy and diploidy) in the sperm.
- The chromosomes 13, 18, 21, X and Y, are most frequently implicated in spontaneous miscarriages and affected offspring with chromosomal abnormalities. In SAT, these chromosomes are analysed by fluorescence in situ hybridization (FISH).
