Sperm Aneuploidy Testing is a diagnostic tool used to determine the treatment options for male infertility. This test helps to identify the proportion of sperm cells with a defective chromosome count in the semen.

Sperm aneuploidy is primarily genetically controlled. Besides that, sperm aneuploidy is associated with
• advanced age
• pollution and cigarette smoking
• alcohol consumption
• cancer chemotherapy
