Current Medical Approaches to the Termination of Unwanted Pregnancies in Dogs

Yıl 2012, Sayı: 1, 1 - 6, 01.01.2012

Öz

Throughout the years, different methods have been used to terminate unwanted pregnancies of dogs which have been often
encountered. These methods may sterilize these aminals as well as after the pegnancy is terminated these methods may also allow
dogs to have an oppurtunity to get pregnant again. Pet owners who do not want their dogs to be sterilized, different pharmacological
agents can be preferred to terminate the unwanted pregnancy. These chemical substances are applied at different terms of the
pregnancy through different tecniques. In recent years, the most commonly used pharmacological agents are prostaglandins, ergot
alkaloids, Mifepristone, Aglepristone, GnRH Agonists and GnRH Antagonists. These edications can be used by themselves , but
they are more successfull when they are used in combination with each other. The endocrinology of dogs is not same in the first and
second half-term of pregnancy. For this reason, the applications to terminate unwanted pregnancies in the first and second half-term
of pregnancies are different from each other.

Köpeklerde İstenmeyen Gebeliklerin Sonlandırılmasına Güncel Medikal Yaklaşımlar

Yıl 2012, Sayı: 1, 1 - 6, 01.01.2012

Öz

Köpeklerde, sıklıkla karşılaşılan istenmeyen gebeliklerin sonlandırılmasında yıllardır farklı yöntemler kullanılmaktadır. Bu
yöntemler hayvanların bir daha gebe kalmasını engelleyebildiği gibi, mevcut gebeliğin sonlandırılmasını takiben tekrar gebe
kalmasına da olanak sağlar. Hayvanların kalıcı olarak doğurganlığını kaybetmesini istemeyen hayvan sahipleri için, istenmeyen
gebeliği sonlandırmak amacıyla çeşitli farmakolojik ajanlar tercih edilir. Bu kimyasal maddeler gebeliğin farklı dönemlerinde farklı
yöntemlerle uygulanmaktadır. Son yıllarda en çok kullanılan farmakolojik maddeler; Prostaglandinler, Ergot Alkaloidleri,
Mifepristone, Aglepristone, GnRH Agonistleri ve GnRH Antagonistleri’dir. Bu ilaçlar tek başlarına kullanılabildiği gibi, birlikte
kullanıldıklarında daha başarılıdırlar. Köpeklerde gebeliğin ilk ve ikinci yarısında endokrinoloji farklıdır. Bu nedenle istenmeyen
gebeliklerin sonlandırılması için yapılan girişimler gebeliğin ilk yarısı ve ikinci yarısı için farklılık gösterir.
