Tekelerde Oksitosin ve PGF2α Enjeksiyonlarının Sperma Kalitesi ve Libido Üzerine Etkisi

Bu çalışmanın amacı, ekzojen yoldan uygulanan oksitosin ve PGF2α’nın seminal plasma ve libido seksüalis üzerine olan etkilerini değerlendirmekti. Bu hormonların sezon içi erkek reprodüksiyonu üzerindeki rolünü araştırmak için, 20 Norduz tekesinden (3-4 yaş) haftada iki kez suni vajina ile alınan sperma numuneleri, beş replikasyon ile gerçekleştirildi. Tekeler rastgele beş gruba ayrılarak, sperm alma işleminden 20 dk önce, kontrol grubu 2 mL sodyum klorür, %0.9 (w/v)) ile i.m., deney grupları ise oksitosin 10 IU, i.v. (Grup 1, n = 5), oksitosin 20 IU, i.v. (Grup 2, n = 5), PGF2α 5 mg, i.m. (Grup 3, n = 5) ve PGF2α 10 mg, i.m. (Grup 4, n = 5) olarak uygulandı. Deney grupları arasında motilite açısından istatistiksel fark tespit edilmedi (P>0.05). Ancak sperma hacmi, konsantrasyon, anormal spermatozoa oranı, intakt membran oranı ve libido sonuçları gruplar arasında istatistiksel olarak anlamlı bulundu (P

The Effects of Oxytocin and PGF2α Injections on Semen Quality and Libido in Buck

The aim of the present study was to evaluate the effects of exogenous oxytocin and PGF2α on seminal quality and libido sexualis in bucks.To investigate the role of these hormones on male fertility, semen samples from 20 Norduz bucks (3-4 years of age) were collected withan artificial vagina twice a week with five replications in breeding season. Bucks were randomly assigned to five groups, control groupwas administered with 2 mL of sodium chloride, 0.9% (w/v)) i.m., whilst the experimental groups were administered with oxytocin 10 IU,i.v. (Group 1, n = 5), oxytocin 20 IU, i.v. (Group 2, n = 5), PGF2α 5 mg, i.m. (Group 3, n = 5) or PGF2α 10 mg, i.m. (Group 4, n = 5) 20 min beforeeach collection. There was no statistical difference between the treatment groups in terms of motility (P>0.05). However, semen volume,concentration, abnormal spermatozoa rate, intact membrane rate and libido results were statistically significant among the different groups(P
