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).
