Abstract

Effective ram sperm cryopreservation protocols, which would yield acceptable fertility rates following artificial insemination (AI) in ewes, are currently lacking. During the process of cryopreservation, spermatozoa are exposed to osmotic pressure and heat stress at different rates. To reduce these negative effects on spermatozoa, new freezing methods and extenders are being tried to develop. The objectives of the current studies are to compare the effects of various anisoosmatic conditions, cryoprotective agents (CAPs) on the motility, acrosome and membrane integrity of Awassi sperm. In the mating season, the sperm was collected from 2 Awassi ram than has been mixed and used. Two experiments were conducted. In experiment 1, the sperm was exposed to 75, 150, 225, 325, 425, 600 and 900±5 mOsm/kg sucrose solutions, held for 5 min and then returned to isosmotic condition. In experiment 2, the sperm was exposed to 0.5, 1.0 and 1.5 M glycerol (Gly), dimethyl sulfoxide (DMSO), ethylene glycol (EG) and propylene glycol (PG) for 5 min and then returned to isosmotic condition. The sperm was evaluated by microscopic assessment of the sperm motility, acrosome and membrane integrity. The motility of ram sperm was significantly affected from anisosmotic stress (P

Özet

Günümüzde koyunlarda dondurulmuş sperma ile yapılan tohumlamalardan yeterli oranda fertilite elde edilememektedir. Dondurma işlemi esnasında spermatozoa değişik oranlarda ozmotik basınç ve ısı stresine maruz kalır. Spermatozoa üzerinde oluşan bu olumsuz etkilerin azaltılması için dondurma metotları ve yeni sulandırıcılar denenmektedir. Bu çalışmanın amacı, anizo-ozmotik ortam ve kryoprotektanların ivesi spermatozoonları üzerine olan etkisini motilite, membran ve akrozom bütünlüğü yönünden değerlendirmektir. Sunulan araştırmada; çiftleşme sezonu içerisinde olan iki adet ivesi koçtan suni vajen yöntemiyle alınan ejakülatlar birleştirilip kullanıldı. Çalışma iki aşamadan oluşmaktadır. Birinci aşamada; sperma 75, 150, 225, 325, 425, 600 ve 900±5 miliosmollük (mOsm)/kg sükroz solüsyonuna 5 dakika maruz bırakılıp yeniden izo-ozmotik duruma getirildi. İkinci aşamada, sperma 0.5, 1.0 ve 1.5 M gliserol (Gly), dimetilsülfoksid (DMSO), etilen glikol (EG) ve propilen glikol (PG) içeren solüsyonlara 5 dakika maruz bırakılıp yeniden izoozmotik duruma getirildi. Spermalar motilite, membran ve akrozom bütünlüğü yönünden değerlendirildi. Koç spermatozoonlarının motilitesi, izo-ozmotik olmayan stres faktörlerinden önemli derecede etkilendi (P
