Abstract

Çalışmada Konya HAYMAREN ve Bandırma KAE ile TiG EM Altınova işletmesi'nde 1 993 ve 1 994 yılı, Polatlı ve Karacabey işletmelerinde 1 994 yılı doğumlu 5578 erkek merinos kriptorşizm ve testis hipoplazisi yönünden muayene edildi. 1993 ve 1 994 yıllarına göre sırasıyla kriptorşizm; Konya HAYMAREN' de% 1 0.3,% 8.5, Bandırma KAE' de% 23.2, % 7.1 , Altınova Işletmesi'nde % 5.7, % 2.9, Polatlı işletmesi'nde - , % 5.6, Karacabey Işletmesi'nde -, % 8.5, testis hipoplazisi; Konya HAYMAREN' de% 5.9,% 6.3; Bandırma KAE' de% 5.7, - ; Altınova işletmesinde% 6.7, -, oranı nda tespit edilmiştir. Kriptorşizm olgularının% 67.7' si bilateral,% 32.3' ü unilateral (% 83.2' si sağ unilateral) , hipoplazi olgularının ise% 69.6' sı bilateral, % 30.4' ü unilateraldi (%'64.7' si sol unilateral). Bunlardan belirli sayıda erkek merinos ayrılarak spermatolojik muayeneler ve plazma testosteron, LH ve FSH düzeyleri belirlendi. Daha sonra hayvanlar 1 2 aylık olunca kesilerek makroskobik ve mikroskobik patolojik bulgular kaydedildi. Kriptorşid testislerde TSC' lar sadece fötal sertali hücreleri ile döşeliydi ve çapları çok küçüklü. Hipoplazik testislerde TSC' larda spermatogenezis, hafif derecelilerde sepermatid, orta derecelilerde sekunder spermatosit safhasında durmuştu. Spermatolojik muayenelerde bilateral orta dereceli hipoplazik olgularda azoospermi gözlendi. Kriptorşid olgularda plazma testesteren düzeyleri normal veya hafif yüksek, LH püzeyleri ise oldukça yüksekti. Kriptorşizm ve hipapiazi olguları nda FSH düzeyleri de artmıştı. Çalışmada elde edilen kr.iptorşizm insidansinin genelde yüksek olduğu, bunun da muhtemelen herediter bir nedenden olabileceği, bu yüksek insidensirı seleksiyonla düşürülebileceği kanısına varıldı. Testislerde patolojik değişikliklerin cinsel olgunluktan önce pek gelişmediği, testis hipoplazisi yönünden değerlendirmelerde yaşı n 12 aydan az olmaması gerektiği izlenimi edinilmiştir

Abstract

Total of 5578 male merinos were evaluated for cryptorchidism and testis hypoplasia in HAYMAREN Konya, KAE- Bandırma. and TIG EM- Altınova, born in 1 993 and 1 994, Polatlı and Karacabey in 1 994. The ineidence of cryptorchidism was 1 0.3 and 8.5% in Haymaren- Konya, 23.2 and 7.1 %in KAE- Bandı rma, 5.7 and 2.9% in Altınova, N/A and 5.6 % in Polatlı, N/A and 8.5% in Karacabey in 1 993 and 1994, respectively. The ineidence of testis hypoplasia was 5.3 and 6.3% in Haymaren- Konya, 5.7% and N/A in KAE- Bandırma, 6.7% and N/A in Altınova in 1993 and 1994, respectively. 67.7 % bilateral and 32.3 % unilateral, of which, 83.2 % was right cryptorchid testes were detected. 69.6 % bilateral and 30.4 % unilateral, of which, 64.7 % left hypoplastic testes were detected.Certain nummer of rams with cryptorchid and hypoplastic testes was selected for plasma levels of testosterone, LH , FSH and spermatologic evaluation. When the rams reached 1 year of age, they were terminated, and the testes were subjected to microscopic and macroscopic evaluations. Tubulus seminiferus contortuses were covered with foetal serteli cells, smail in diameter in cryptorchid testes. Spermatogenesis ceased at spermatid and secondary spermatocyte phases in light and moderate hypoplastic testes, respectively. Bilateral moderate degree hypoplasia was characterised by azoospermia. While plasma testosterone levels were within normal limits orhighly increased, LH levels were highly increased in cryptorchid testes. FSH levels were found to be highly increased in cryptorchid and hypoplastic testes. ln this study, the ineidence of cryptorchidism was found to be high and attributed to the hereditary factors, which was thought that would be decreased by selection. Pathological changes found was not to be detectable until sexual maturity. lt was concluded that the rams must be at least 1 2 months old in order to detect the hypoplastic testes
