دراسة بعض الخصائص الفيزيوكيمياوية للسائل المنوي في الاكباش المحلية في منطقة اهوار جنوب العراق (الجبايش)

Abstract

The effects of seasonal variation on the quality of seminal fluid on marsh land local rams were studied to evalute the changes in physo-chemical characteristics (seminal fluid volume, sperm viability, primary sperm motility, seminal fluid pH and fructose concentration). The physo-chemical characteristics of seminal fluid were affected by temparature and day light ratio.The highest volume for seminal fluid was recorded in summer (1.12 ml) , however the volume was declined to 0.73 and 0.53 ml in spring and winter respectivily. The least sperm motility (33%) was recorded in summer,while the highest motility (41%) was recorded in spring. The highast viable sperm % was recorded in spring (83.13%), which declined to (66.17%) in summer. seminal fluid pH is more acidic (6.52) in spring in comparison with summer (6.95). The study showed that there is asignificant increase in the seminal fluid fructose concentration in summer which reached (758.94mg/100ml).The study confirmed that seminal fluid quality was significantly improved during spring and winter.
