Kedilerde Ovaryum Fizyolojisi

Abstract

Ovaryum, üreme ile ilgili fizyolojik fonksiyonları kontrol eden birçok farklılaşmış hücre tipini içermektedir. Ovaryum üzerinde bulunan herbir follikül, bir adet oosit ve onun etrafını saran özelleşmiş hücrelerden oluşmaktadır. Bu folliküllerin herbiri ovule olabilecek sağlıklı bir oosit geliştirmeyi hedefler. Kedi ve tavşanlarda bir follikülün ovule olması diğer hayvanlardan farklı olarak, vajinal uyarımla gerçekleşir. Kediler mevsime bağlı poliöstrik hayvanlardır. Gebelik veya yalancı gebelik şekillenmedikçe, kedilerde çiftleşme sezonu boyunca östrüs siklusu tekrar eder. Östrüs siklusu boyunca ovaryum üzerinde meydana gelen değişimler folliküler ve luteal dönem olmak üzere iki dönem altında toplanmaktadır. Bu derlemede kedi ovaryumunun genel yapısı, üremenin hormonal kontrolü, folliküler ve luteal dönemler hakkında özlü bilgilerin verilmesi amaçlanmaktadır
