Abstract

Dichlorvos is one of organophosphate insect pesticides which is widely distributed in environment. This study deals with the effect of this pesticide on sperms number , sperm abnormalities and spermatogenesis in laboratory male mice (Mus musculus L.) which were treated with (0.1 mg/day , 0.05 mg/day ) of the pesticide for a period of 15 day. intraperitoneal injection of Dichlorvos in laboratory mice resulted in a significant decrease in sperms number with both doses as compared with the control group. The result also showed a significant increase of sperm abnormalities with both doses. Moreover, pesticide injection caused a significant decrease in spermatogonia and primary spermatocyte with both doses whereas the statistical analysis did not show any significant difference in tubular diameter when compared with the control group.

الدايكلورفوس من المبيدات العضوية الفسفورية الحشرية الواسعة الانتشار في البيئة ،اذ تناولت هذه الدراسة تأثير هذا المبيد على عدد النطف وتشوهاتها وعلى عملية نشأة النطف لذكور الفئران المختبرية Mus musculus L. والمعاملة بالجرعتين (0.1 ملغم/يوم و 0.05 ملغم/يوم) ، ولمده 15 يوماً .أظهرنتائج حقن مبيد الدايكلورفوس في منطقة الخلب I.P. للفئران المختبرية أنخفاض معنوي في عدد النطف وبالجرعتين عند مقارنته مع مجموعة السيطرة. كما بينت النتائج وجود أرتفاع معنوي في تشوهات النطف وبالجرعتين، بالاضافة الى ذالك ، ان حقن المبيد سبب انخفاض معنوي في عدد خلايا سليفات النطف وعدد الخلايا النطفية الابتدائية وبالجرعتين ، بينما لم يظهر التحليل الإحصائي وجود أي فارق معنوي لقطر النبيب المنوي عند مقارنته مع مجموعة السيطرة.

Abstract

Morphologically,the testes of adult duck was suspended by mesorchium with the roof of the the abdominal cavity. The testes appear as elongated bean shaped and situated asymmetrically. The mean average of the testis was 1,48 cm in length, 0.47cm in width, and 1.54gm in weight. Histologically, each testis was covered by a connective tissue capsule.The stroma of the testis posses no mediastinum. Leydic cells were commonly found in groups within the connective tissue which filled the spaces between the seminiferous tubules. Germ cells and Sertoli cells constituent the main component of the seminiferous epithelium. There were type A-spermatogonia, type I-spermatogonia, and type B-spermatogonia. Type B-spermatogonia passes through proleptoten, leptotene, zygotene, pachytene, diplotene, and diakineses. The primary spermatocytes give rise to secondary spermatocytes. These latter cells enter the second meiotic division to form the spermatids which undergo through thirteenth stages to form the sperms.
