Methods： Thirty male rats were divided into five groups： group 1 （untreated） and groups 2, 3, 4 and 5 were fed for 30 days with 5%, 10%, 15% and 30% crude garlic, respectively. Testes and accessory organs were weighed and some markers were assessed. Light and electron microscopy observations were also performed. Results： A significant decrease was observed in the body weight of groups 4 （14%; P 〈 0.01） and 5 （20%; P 〈 0.01）; of the prostate weight in group 5 （29.1%; P 〈 0.05） and of seminal vesicle weight in groups 3 （14.4%; P 〈 0.01）, 4 （18.3%; P 〈 0.01） and 5 （27.3%; P 〈 0.01）. In contrast, testis and epididymis weights were unchanged. In epididymis tissue, the alpha glucosidase activity and the spermatozoa density were unchanged. The treatment resulted in a significant decrease in testosterone serum levels in groups 3 （77.3%; P 〈 0.01）, 4 （77.3%; P 〈 0.01） and 5 （90.9%; P 〈 0.01）, associated with a significant increase in LH serum levels （P 〈 0.01）. Testicular histology showed a dose-dependent increase in the percentage of empty seminiferous tubules. Moreover, testicular function was affected; a significant decrease in phosphatase acid activity （P 〈 0.01） and testosterone （P 〈 0.05） contents were observed. Conclusion： Crude garlic consumption during 1 month reduced testosterone secretion and altered spermatogenesis at 10%, 15% and 30% doses.展开更多
