Abstract

In this study, the effect of glucose on in-vitro capacitation of frozen-thawed bull semen was investigated. For this purpose, sperm were incubated with a dose of 100 mg/ml heparin in the presence (HG) or absence of 5 mM glucose (H) for a 60 min. Heparin induced capacitation was determined by the undergo an acrosome reaction upon exposure to 100 mg/ml lysophosphatidylcholine (LC). To be able to determine the reaction, spermatozoa were stained by Giemsa. The acrosome stained dark pink for the non-reacted sperm and remain unstained for the reacted sperm. Mean proportions of acrosome reacted spermatozoa for the HG and H groups were 20.8% and 43.4% respectively. Consequently, when sperm were incubated under capacitating conditions with heparin plus glucose reduced the LC induced acrosome reactions (p<0.001).

Özet

Bu araştırmada, glukozun dondurulmuş boğa spermatozoonlarının in-vitro kapasitasyonu üzerine etkisi araştırıldı. Bu amaçla sperma, 5 mM glukoz içeren (HG) ve glukoz içermeyen (H) mediumlarda 100 mg/ml heparin ile 60 dakika inkübasyona bırakıldı. Heparin ile kapasitasyonun sağlanmasından sonra her iki gruba da 100 mg/ml lizofosfatidilkolin (LC) ilave edilerek akrozom reaksiyonunu indüklendi. Meydana gelen reaksiyon, Giemsa ile yapılan boyamayla tespit edildi. Boyama sonucunda reaksiyon geçirmeyen spermatozoonların akrozomu koyu pembe boyanırken reaksiyon geçirenler boya almadan kaldı. HG grubu için reaksiyon geçirmiş spermatozoon ortalamaları %20.8 olurken, H grubu için bu oran %43.4 olarak tespit edildi. Sonuç olarak; sperma heparin ile kapasitasyon koşullarında inkübe edildiğinde ortamda bulunan glukoz, kapasitasyona uğramış spermatozoon oranlarında azalmaya (p<0.001) neden oldu.
