The Sperm Aneuploidy Test (SAT) is a diagnostic test to study the genetic etiology 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, mostly implicated in spontaneous miscarriages and affected offspring with chromosomal abnormalities, are analyzed by fluorescence in situ hybridization.
An increase of sperm chromosomal abnormalities affects three levels:
EMBRYO LEVEL:

PREGNANCY LEVEL:
