Y\u00f6ntemde baba aday\u0131ndan al\u0131nan sperm \u00f6rneklerinin g\u00f6revi d\u00f6llenmeyi sa\u011flayacak en iyi spermi se\u00e7mek olan mikro\u00e7ipteki kanallara konulup do\u011fal ortam\u0131ndaki gibi yar\u0131\u015fmalar\u0131 sa\u011flan\u0131yor.

\u0130nsanlarda uygulad\u0131klar\u0131 mikro\u00e7ip y\u00f6nteminin bir benzerini de hayvanlarda suni tohumlama i\u00e7in uygulamaya ba\u015flad\u0131klar\u0131n\u0131 anlatan Prof. Dr. Demirci, “\u00c7iple elde edilen sperm ile hem yap\u0131lan suni tohumlama hem gebelik oran\u0131n\u0131 art\u0131r\u0131yor, hem de sa\u011fl\u0131kl\u0131 gebeliklerle hayvanlarda hastal\u0131k, d\u00fc\u015f\u00fck, \u00f6l\u00fcm gibi olaylara daha az rastlan\u0131yor. Bu teknolojiyle hayvanc\u0131l\u0131kta uzun d\u00f6nemde verimin b\u00fcy\u00fck oranda artaca\u011f\u0131n\u0131 tahmin ediyorum” diye konu\u015ftu.<\/p>\n
“Gebelik oran\u0131 y\u00fczde 60\u2019tan y\u00fczde 90\u2019a \u00e7\u0131kt\u0131”<\/p>\n
Teknolojiyi d\u00fcnyada ilk kez tesislerinde uygulayan Egevet\u2019in kurucu orta\u011f\u0131 Ahmet Gedik ise mikro\u00e7ip y\u00f6ntemini bir s\u00fcredir uygulad\u0131klar\u0131n\u0131 ve sonu\u00e7lar\u0131n olduk\u00e7a ba\u015far\u0131l\u0131 oldu\u011funu s\u00f6yledi. Tesislerde y\u0131lda 1 milyon doz sperm \u00fcreterek piyasaya s\u00fcrd\u00fcklerini kaydeden Gedik, “Her ne kadar en iyi \u0131rkta bo\u011falar \u00e7iftli\u011fimizde en iyi \u015fartlarda bak\u0131l\u0131yorsa da, hava \u015fartlar\u0131n\u0131n de\u011fi\u015fti\u011fi d\u00f6nemlerde hayvanlar \u0131s\u0131 stresine girdi\u011fi i\u00e7in ald\u0131\u011f\u0131m\u0131z sperm \u00f6rneklerini mikroskopta inceledi\u011fimizde hareketli sperm bulamad\u0131\u011f\u0131m\u0131z i\u00e7in at\u0131yorduk. \u015eimdi ise bu \u00e7ipler sayesinde \u00e7\u00f6pe at\u0131lacak spermlerde bile en iyi spermleri bulup, y\u00fczde 80-90 oran\u0131nda ba\u015far\u0131 elde ediyoruz” dedi.<\/p>\n
Suni tohumlamayla gebe kalma oran\u0131n\u0131n daha \u00f6nceleri y\u00fczde 60\u2019larda oldu\u011funu anlatan Ahmet Gedik, “\u00c7ip y\u00f6ntemiyle yap\u0131lan suni tohumlamayla gebelik \u015fans\u0131 y\u00fczde 90\u2019a yak\u0131n bir orana \u00e7\u0131k\u0131yor” ifadelerini kulland\u0131.<\/p>\n
Mikro\u00e7iplerin faydalar\u0131<\/p>\n
Mikro\u00e7iplerin, DNA kalitesi ve fizyolojik olarak en iyi durumdaki spermlerin se\u00e7ilmesini sa\u011flad\u0131\u011f\u0131 ve suni tohumlama yap\u0131lan hayvan\u0131n gebelik \u015fans\u0131n\u0131n daha \u00e7ok artt\u0131\u011f\u0131 belirtilfi. Laboratuvarlarda uzun i\u015flemlerin ortadan kalkmas\u0131 ile sadece 30 dakika gibi k\u0131sa bir s\u00fcrede en verimli sonucun elde edilmesi sa\u011fland\u0131\u011f\u0131 bildirildi. G\u00fcn\u00fcm\u00fczde kullan\u0131lan y\u00f6ntemlerin aksine santrif\u00fcjleme, kar\u0131\u015ft\u0131rma gibi fiziksel olarak canl\u0131 h\u00fccreye zarar verebilecek olan i\u015flemlerin kullan\u0131lmad\u0131\u011f\u0131 \u00e7ip y\u00f6nteminde malzeme ve sol\u00fcsyon gibi de\u011fi\u015fkenlerden kaynaklanan hata ve i\u015flem farkl\u0131l\u0131klar\u0131n\u0131n da ortadan kalkt\u0131\u011f\u0131 kaydedildi.<\/p>\n","protected":false},"excerpt":{"rendered":"
