Effect of a nanocrystalline cerium dioxide (nanoceria) on the reproductive system of elderly male rats has been studied. It was shown that nanoceria administration (1 mg/kg for 10 days) considerably increases testosterone level, quantity of spermatozoa and quantity of rat cubs in the litter born by pubertal intact females. Physical and sexual development of rat cubs in the test group did not differ from the control.

Keywords: ananocrystalline cerium dioxide, male rats, testosterone, spermatozoa.

  1. Woah! I’m really digging the template/theme of this blog. It’s simple, yet effective. A lot of times it’s hard to get that “perfect balance” between superb usability and appearance. I must say that you’ve done a fantastic job with this. Additionally, the blog loads super fast for me on Firefox. Superb Blog!
