ABSTRACT
The present work was a trial to study the effect of ceftriaxone on the reproductive system in male Albino rats. Moreover, some biochemical parameters were also investigated. Fourty-five mature male albino rats weighing from 120 -160 g each of 4-5 month old were used in this study. The animals were divided into 3 equal groups, each of 15 rats. The first and second groups were injected I/M for 5 consecutive days with ceftriaxone at the dose level of 75 mg/kg B.wt. and 300 mg/kg B.wt. respectively. The third group was kept as control and injected I/M with 0.3 ml saline/ rat for 5 consecutive days. The obtained results showed that administration of ceftriaxone induced a variety of side effects. These are represented by reduction of testes, epididymis and accessory sex organ weight, changes in sperm characters [decrease of sperm count and motility] and increase of sperm abnormalities. Moreover, the liver functions were significantly affected. Therefore, caution is required when using large doses of ceftriaxone due to its toxicity to reproductive organs as well as its increasing effect on liver enzymes
