Abstract

İn seasonaly breeding mammals that use changes in the photoperiod to time their reproductive cycles, temporal signals to the reproductive system are controlled by the daily rhythm in melatonin production. There is a daily rhythm in the production of the pineal hormone melatonin in all mammalian species. Production is stimulated by darkness and inhibited by light. This provides a signal reflecting the changing environmental lighting cycle. Melatonin has an effect on the development of sex and reproduction. Animals that are photoperiodic administration of melatonin allows the extension of the reproductive season. Melatonin effects reproductive physiology. However, its mechanism of action, target cells and decromposition have not been completely elucidated. The use of exogenous melatonin to manipulate reproduction in various mammals has recently been studied extensively

Özet

Fotoperiyodik değişimlerden etkilenerek mevsimsel üreme gösteren memelilerde, reprodüktif siklus zamanı ve reprodüktif sistemdeki değişiklikler melatonin üretimindeki günlük ritimle kontrol edilir. Bütün memeli türlerinde epifiz hormonu olan melatonin üretiminde günlük ritim vardır. Üretim ışıkla inhibe olurken, karanlıkla birlikte aktive olmaktadır. Öte yandan cinsiyetin gelişimi ve üreme üzerine de melatoninin etkisi bulunmaktadır. Fotoperiyodik hayvanlarda, melatonin uygulaması ile üreme sezonunun uzatılması mümkün olmaktadır. Melatonin, üreme fizyolojisi üzerinde de rol oynamaktadır. Fakat etki mekanizması, hedef hücreleri ve yıkımlanması henüz tam olarak açıklanamamıştır. Bu arada, son zamanlarda bazı memelilerde reprodüksiyonun kontrolünde eksojen melatonin uygulaması yaygın biçimde kullanılmaktadır.
