WebDisruption of such controls can lead to infertility or germ cell tumors (GCTs). GCTs are particularly hideous pathologies since they occur mainly in neonates, infants, and children, rarely in the adults. They arise primarily in the testes and ovaries, though they can also develop in extragonadal sites along the midline of the body and the brain. http://mdedge.ma1.medscape.com/obgyn/article/108085/gynecology/understanding-ovarian-germ-cell-neoplasms

The mechanism by which trisomy 21 affects male infertility remains unclear, but it is hypothesized that it may be due to areduced proliferation of primordial germ cells during migration to the gonadal ridge, perhaps associated with an accelerated rate of apoptosis (Patrizio and Broomfield, 1999).
