Abstract: The onion (Allium cepa) has long been used in traditional medicine is one of the important Allium species commonly used in the daily diet and has recently been the source of much interest because of its antithrombotic, hypolipidaemic, hypotensive, diaphoretic, antibiotic, antidiabetic, antiatherogenic and anticancer medicinal properties. Zinc deficiency causes primary testicular failure and altered testicular steroidogenesis. The aim of present study was to evaluation of onion (Allium cepa. Linn) aqueous extract on serum concentration of LH, FSH and testosterone compared with Zn sulfate supplementation in the rats. In this experiment, 162 mature male rats (250 g on the average) were acquired from Razi Serum-Producing Institute of Karaj and transferred to keeping place. This design is performed as a factorial experiment 3x3 (3 level of onion extract and 3 level of zinc sulfate complement) in the form of totally random design with 9 groups per 3 replications each containing 6 rats. All of keeping cages were disinfected before performing the experiment. Data showed that the effect of different levels of zinc supplementation and onion extract was significant on the concentrations of these hormones, p<0.05. The combined use of onion and Zn was more significant on LH and FSH and no significant on testosterone, p<0.01. Treatment group 9 has highest increase in the amount of LH and FSH. The reason of this fact that contrary, the concentration of testosterone showed no increase in the experimental groups treated with onion and Zn supplementation probably can be attribute to the negative feedback effect of this hormone versus LH and FSH.
