Male pseudohermaphroditism in a lamb

Bu çalışmada; 4 aylık, Akkaraman ırkı bir kuzuda erkek psödohermafroditizm makroskobik ve mikroskobik olarak tanımlandı. Kuzu görsel bakıda sahip olduğu dış genital organ vulvası ile dişi görünmekteydi. Ancak kuzu iç genital organ olarak testislere ve epididimise benzer yapıya sahipti. Histolojik incelemede normal vulva dokusu görüldü. Testiste ise olgunlaşmamış seminifer tubullerin sadece sertoli hücreleri ve primitif eşey hücrelerine benzer yapılar ile döşeli olduğu gözlendi. Epididimisin mikroskobik incelemesinde kistik tubul benzeri yapılar ile primitif ve degeneratif eşey hücrelerine benzer hücreler görüldü.
