Abstract: 

Background: Hyperactivity of testosterone is one cause of infertility and its incorrect use can produces reproductive disorders. Nettle (Urtica dioica) has antiandrogenic effect and may antagonized effect of testosterone. In present study structure of testes of golden hamster was evaluated after testosterone and extract.
Materials and Methods: In this experimental and animal modeling study, twenty male mature hamsters were divided to 4 groups, group 1 was control, group 2 received testosterone at dose 3 mg/kg subcutaneously, group 3 received nettle extract dose 30 mg/kg orally and group 4 received testosterone and nettle for 30 days daily. The hamsters were euthanized and testes were removed and detected macroscopic parameters (weight, height, wide and volume) and fixed with formalin. The samples were sectioned and colored with H & E.
Results: The volume, weight, length and wide of testes was at least in testosterone group and statistically was lesser than control and testosterone -nettle group (p<0.05), but did not the height epithelium of seminifer tubules, compact of spermatogenic cells and number of serotolli cells in testosterone group was lesser than control group significantly (p<0.05).
Conclusion: The nettle extract decreased histological changes of testes by testosterone and improved its structure.
