The present study was conducted to evaluate the ameliorative effects of Allium sativum (garlic) as well as Spirulina maxima on lead acetate toxicity in rat testes. Forty adult, male, albino rats were divided into four groups (10 rats/each): group I served as the control; group II contained rats that received lead acetate (100 mg/kg); group III contained rats that received both lead acetate (100 mg/kg) and garlic (600 mg/kg); and group IV contained rats that received both lead acetate (100 mg/kg) and spirulina (500 mg/kg). All treatments were performed daily for one month. Serum testosterone levels, oxidative stress parameters, expression of the caspase-3 gene and histological, histo-morphometric and ultrastructure alterations in the testes were investigated. The results revealed that the Pb-treated group exhibited a significant increase in MDA concentration concomitantly with a decrease in serum testosterone levels, antioxidative marker levels and caspase-3 gene expression. Several histological and histo-morphometric alterations were observed in this group. Co-administration with spirulina or garlic caused a significant increase in testosterone levels, testicular SOD and CAT activities, and caspase-3 gene expression and a decrease in MDA levels, with improvement in histological and histo-morphometric alterations. These results suggested that spirulina was more effective at providing protection against Pb-induced reproductive damage in rats than garlic, indicating the beneficial role of spirulina in improvement of spermatogenesis and steroidogenesis after lead exposure.
