Effect of altitude on some male fertility related traits in Saudi ovine and caprine species

This study aimed to evaluate the effect of altitude on some male fertility related traits in Saudi sheep and goats. Testicular tissues were collected from a slaughterhouse in Taif governorate (1800 m above sea level) and Makkah governorate (sea level). Sperm characteristics (1 - individual motility,...

Description
Summary:This study aimed to evaluate the effect of altitude on some male fertility related traits in Saudi sheep and goats. Testicular tissues were collected from a slaughterhouse in Taif governorate (1800 m above sea level) and Makkah governorate (sea level). Sperm characteristics (1 - individual motility, 2 - percent live sperm 3 - percent abnormal sperm) were examined. Semi-quantitative RT -PCR assay was used to evaluate the expression of IGF-II, StAR, LDLr and CYP11A genes. No significant effect of altitude on tested sperm parameters was revealed. Expression of IGF-II gene in both sheep and goats was significantly (P
