What is Y Chromosome Deletions ( DNA ) – 10?

Y Chromosome Deletions (DNA) – 10 is a blood test that helps detect the abnormality in the Y chromosome gene. The absence of a single or multiple genes in the Y chromosome can lead to a genetic condition called Y chromosome deletion. This disorder decreases the sperm count in males leading to infertility.

This test is indicated in males who are producing no sperm or a lesser number of sperm cells. In some cases, the sperm cells may be abnormal in shape as well. Since this condition is a genetic disorder, if the patient is able to father children, the faulty Y chromosome is transferred to the son. The daughters do not inherit the faulty chromosome since they do not get the Y chromosome.
