Electron microscopical studies were also performed to define any histological changes in the testis upon infection with S. mansoni. The serum levels of gonadotropins (FSH, LH) showed no significant changes in infected as compared to control mice. On the other hand, the serum level of testosterone showed a significant decrease (P < 0.001) in infected as compared to control mice starting form the 14th week post infection. Testicular lipids showed a significant increase (P < 0.01) in the concentration of total cholesterol and a significant decrease (P < 0.005) in the concentration of total triacylglycerols in infected as compared to control mice especially at late stages on infection (14-20 weeks post infection). However, electron microscopical studies showed non significant histological changes in the testicular tissues of infected mice at different stages of infection. It is concluded that schistosomiasis has an important metabolic effect on testicular lipids as well as on the serum level of testosterone, whereas structural changes and spermatogenesis might require a longer period of infection and/or severe infection with higher number of cercariae  ردمد : 0253-5890  اسم الدورية : Journal of the Egyptian Society of Parasitology  المجلد : 27  العدد : 2  سنة النشر : 1418 هـ 1997 م  نوع المقالة : مقالة علمية  تاريخ الاضافة على الموقع : Friday, December 2, 2011  الباحثون اسم الباحث (عربي) اسم الباحث (انجليزي) نوع الباحث المرتبة العلمية البريد الالكتروني زهير المرزوقي Marzouki, Zohair باحث رئيسي دكتوراه   عدنان أمين Amin, Adnan باحث مشارك دكتوراه   الملفات اسم الملف النوع الوصف  31481.pdf pdf   الرجوع إلى صفحة الأبحاث
