Canlı neslinin
sürekliliği üreme fonksiyonu ile sağlanır. Bu fonksiyonu gerçekleştiren
organlara ise üreme organları adı
verilir. Üreme ile ilgili fonksiyonları yerine getiren ve seks hormonlarını
salgılayan organların oluşturduğu sisteme de üreme sistemi denir. Kanatlı hayvanların üreme sistemi
memelilere göre daha basit olup önemli farklılıklar içermektedir. Kanatlılarda
erkek üreme sistemi bir çift testis, küçük epididimisler, direkt kloakaya
açılan uzun ve kıvrımlı duktus deferensler ve penis karşılığı bir organ olan
fallus bulunmaktadır. Ayrıca kanatlı hayvanlarda erkek genital bezler
bulunmamaktadır.
