Abstract
At embriyosu ile uterus arasında birbiriyle ilişkili bir dizi karmaşık biyolojik mekanizma mevcuttur. Kısraklarda fertilizasyon oviduktun ampulla ile istmus bölümleri arasında meydana gelir ve ovulasyondan 5-6 gün sonra embriyo ovidukt kanalını geçerek uterusa gelir. Embriyo tarafından salgılanan prostaglandin E2 ve prostaglandin F2α uterotubuler kavşaktan embriyonun geçişine izin verir. Embiyonik vezikül uterus lümeninde 9-14. günler arasında mobildir ve 15-17. günler arasında korpus ile herhangi bir kornu uteri arasındaki fleksür bölgesinin kaudalinde sabitlenir ve hemen sonra oryantasyon şekillenir. At embriyosunun uterus lümeninde migrasyonu ve fiksasyon süreçlerinin daha fazla aydınlatılması, gebe kısraklarda kaotik bir sorun olan ikiz embriyo olgularında ve intrauterin cihaz uygulamaları gibi üremenin denetlenmesi konularında hekimlere operasyonel bir çözüm sunar.

Abstract
A number of complex interrelated biological mechanisms exist between the equine embryo and the uterus. In mares, fertilization occurs between the ampulla and isthmus sections of the oviduct, and 5-6 days after ovulation, the embryo crosses the oviduct and comes to the uterus. Prostaglandin E2 and prostaglandin F2α secreted by the embryo allow the passage of the embryo through the uterotubular junction. The embryonic vesicle is mobile in the uterine lumen from days 9 to 14, and from days 15 to 17 it is fixed in the caudal of the flexure zone between the corpus and any uterine horn, and immediately after which orientation is formed. It provides an operational solution to physicians in the migration of the horse embryo in the uterine lumen and further elucidation of the fixation processes, in cases of twin embryos, which is a chaotic problem in pregnant mares, and in the supervision of reproduction such as intrauterine device applications.
