Kedilerde Östrus Baskılama Yöntemi Olarak Melatonin İmplantlarının Kullanımı

Abstract

Melatonin implantları, dişi kedilerde östrus baskılanması için etkili ve geri döndürülebilir bir yöntem olarak kullanılmaktadır. Mevsimsel poliöstrik hayvanlar olan kediler, üreme döngülerini ışık periyoduna bağlı olarak düzenler ve bu süreçte melatonin, hipotalamik-hipofizer-gonadal aksın kontrolünde kritik bir rol oynar. Subkutan melatonin implantları, kısa gün uzunluğu koşullarını taklit ederek ovaryum aktivitesinin ve östrusla ilişkili davranışların geçici olarak baskılanmasını sağlar. Yapılan çalışmalar, melatonin implantlarının interöstrus aralığını 2–4 ay boyunca uzattığını ve minimal yan etkilere sahip olduğunu göstermektedir. Ancak, östrus baskılanma süresinde görülen bireysel farklılıklar ve bazen ovulasyon ile psödogebelik oluşumu, değişken bireysel yanıtları ortaya koymaktadır. Geleneksel hormonal kontraseptiflerle karşılaştırıldığında, melatonin, progestinler ve androjenlerle ilişkili ciddi yan etkiler olmadan daha güvenli bir alternatif sunmaktadır. Bununla birlikte, uygulama zorlukları, maliyet ve geçici etkililik gibi konular endişe yaratmaktadır. Melatonin dozaj protokollerinin iyileştirilmesi, uzun vadeli etkilerin değerlendirilmesi ve bireysel yanıt farklılıklarının ele alınması için daha fazla araştırmaya ihtiyaç vardır. Melatonin implantları, özellikle cerrahi sterilizasyona alternatif arayan kedi yetiştiricileri ve sahipleri için umut vadeden bir üreme yönetimi aracı olarak öne çıkmaktadır.

The Use of Melatonin Implants as a Method for Estrus Suppression in Cats

Abstract

Melatonin implants have gained attention as an effective and reversible method for estrus suppression in female cats. As seasonally polyestrous animals, cats exhibit cyclic reproductive behavior influenced by photoperiod, with melatonin playing a crucial role in regulating the hypothalamic-pituitary-gonadal axis. Subcutaneous melatonin implants mimic short daylight conditions, leading to a temporary suppression of ovarian activity and estrus-related behaviors. Studies have demonstrated that melatonin implants extend the interest interest interval for 2–4 months with minimal adverse effects. However, variations in estrus suppression duration and occasional induction of ovulation and pseudopregnancy highlight individual variability in response to treatment. Compared to traditional hormonal contraceptives, melatonin offers a safer alternative without the severe side effects associated with progestins and androgens. Despite these advantages, concerns regarding application challenges, cost, and temporary efficacy persist. Further research is needed to refine dosage protocols, evaluate long-term effects, and address individual response differences. Melatonin implants represent a promising tool for feline reproductive management, particularly for cat breeders and owners seeking a non-surgical alternative to sterilization.
