The sperm aneuploidy test is a genetic test that determines if a male parent has an increased chance of carrying chromosomal abnormalities in his sperm. The sperm aneuploidy tests analyzes 5 chromosomes: 13, 18, 21, X and Y. This test can provide an indication of the chances of abnormal genetic development in the sperm. Embryos normally have 46 chromosomes, with half coming from the father and the other half from the mother. Some embryos have an aneuploidy where there is a numerical abnormality in the number of chromosomes causing birth defects in the baby. Usually, the errors that cause aneuploidy come from the mother; however there are certain circumstances where the sperm is the cause of the aneuploidy. This diagnostic test can be used to determine sperm chromosomal abnormalities. Studies show that aneuploidy in the sperm has been associated with a lower pregnancy rate after ICSI as well as a higher miscarriage rate. These chromosomal abnormalities can cause implantation failure, miscarriage or birth of a baby with physical disabilities.
