This study was applied to investigate the effect of copper oxide on spermatogenesis in reproductive system of albino male Swiss mice . Thirty male mice where divided into four groups . in which of them were treated with different concentration of copper oxide (2 , 4 , 8 )mg/kg for 45 day respectively . The forth groups was the control which treated with normal saline solution . The result showed :-
1.Significant decrease (P<0.05) in number of Spermatogonia were (43,32 ,25) for treated groups (2 ,4 ,8 mg/kg) as compared with the control group(normal saline).
2. Significant decrease (P<0.05) in number of Spermatocyte were (85,64,45) for treated groups (2 ,4 ,8 mg/kg) as compared with the control group(normal saline).
3. Significant decrease (P<0.05) in number of Spermatid were (110,88 ,60) for treated groups (2 ,4 ,8 mg/kg) as compared with the control group(normal saline).
4.Significant decrease (P<0.05) in number of Spermatozoa were (90,72 ,53) for treated groups (2 ,4 ,8 mg/kg) as compared with the control group(normal saline). |
