Does teratozoospermia increase your chances of having a baby with Down syndrome?

No, teratozoospermia is not associated directly with trisomy 21, that is, the chromosomal abnormality that causes Down syndrome. Nonetheless, sperm with an abnormal morphology can cause genetic alterations leading to implantation failure, increase the chances of miscarrying, or other pathologies.
