Abstract
This study was conducted to investigate the effect of watery extract of Cumin plant (200 mg/kg B.W.) on some histological changes of the male reproductive system in albino rabbits. Sixteen adult male rabbits weighting about (200-250 g) and 12-15 weeks age were used in the present study and divided into (2) groups, 8 rabbits per group, group1: serve as a control group and given normal diet with drinking water, group2: Given Cumin extract (200 mg/kg B.W.) through oral tubular feeding, the experiment were continued 60 days for all groups. The results of the current study showed significant decrease (P<0.05) in serum testosterone compared with control group . As for ectopic tissue, water extract (200 mg/kg) has resulted in satisfactory tissue changes of the testes . The water extract of Cumin plant acts as an antioxidant through its important role in curbing the harmful effects of some types of free radicals within the body and histological changes and functions of the male reproductive system of rabbits. The results of histological diagnosis of testes in male rabbits that giving cumin for long periods leads to a decrease in the level of testosterone
