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).
An increase of sperm chromosomal abnormalities affects your reproductive journey at three levels:
EMBRYO LEVEL:
Rodrigo et al., 2010.
PREGNANCY LEVEL:
Rubio et al., 2001.
OFFSPRING LEVEL:
This technique allows the detection of aneuploidy only for the chromosomes included in the test (13, 18, 21, X and Y). In very few ejaculated samples or testicular samples, there is not enough spermatozoa for a proper estimation of the risk of aneuploidy.
Different collection and shipment options are available. Please contact Igenomix at info.uk@igenomix.com to decide the most suitable method for you.
Samples must be accompanied by a completed test requisition form.
