Efficacy of the essential fatty acids from maize oil and peanut on the spermatogenesis in rats

Oil seeds have saturated and nonsaturated essential fatty acids that affect on the spermatogenesis process of testis. In the present study, Twenty-one of male rats newly were taken from breast feeding each group (Control, Maize oil, Peanut oil) consists of seven rats were studied. The rats were fed by maize oil and peanut oil for 10 percent (w/w) of the diet and after three months and achieving to the maturation stage with macroscopic observations, the examination of blood hormones, tissue sections of testicles, and weight and volume measurement of the testis in each group were carried out. Our data of the present study showed that there was a significant decrease in the amount of testosterone and FSH in the treatment groups compared to the control group (P<0.001) while this difference about LH and volume of the testis was P<0.001 for maize oil and P<0.05 for peanut oil. However no significant decrease was observed in weight of the testicles in the treatment groups compared to the control groups. Taken together, the present study shows that consumption of maize oil and peanut oil can be an introduction for the synthesis of prostaglandins, due to the contain of essential fatty acids specially archidonic acid. It is known that, archidonic acid can result on the replication and proliferation of the spermatogony layer of the semenifer tubes (Spermatogenesis process) and it is enabling to affect on the basal metabolism via increase of the insulin activity in the testis. By contrast, in the tube is occurred the inhibition of spermatocyte to spermatosoide conversion.
