Infos zur Erkrankung
Männliche Unfruchtbarkeit kann durch das Fehlen messbarer Mengen an Spermatozoen im Ejakulat (Azoospermie) oder einer Anzahl von Spermien im Ejakulat unter 15 Millionen/ml (Oligozoospermie) gekennzeichnet sein. Die Spermien-Morphologie kann normal sein. Bei obstruktiver Azoospermie werden Spermien produziert, sie können sich aber wegen eines Verschlusses der Samenwege nicht mit der restlichen Ejakulat-Flüssigkeit mischen. Bei nicht-obstruktiver Azoospermie ist die Spermatogenese selbst gestört. Zu den bekannten genetischen Ursachen einer Azoospermie oder Oligospermie zählen Mutationen einzelner Gene bzw. Deletionen der Azoospermie-Faktoren-(AZF-)Region auf dem langen Arm des Y-Chromosoms. Es handelt sich in der Regel um de novo Ereignisse. Die diagnostische Ausbeute bei Azoospermie variiert in den verschiedenen ätiologischen Kategorien, von ~30% bei nicht-obstruktiver Azoospermie auf der Basis primär testikulärer Ursachen und bis zu 90% beim kongenitalen bilateralen Fehlen des Vas deferens.
