Vitamins E and C Alleviate the Germ Cell Loss and Oxidative Stress in Cryptorchidism When Administered Separately but Not When Combined in Rats

الملخص EN

The antioxidant effects of vitamins C and E on cryptorchidism-induced oxidative stress were investigated in male Sprague-Dawley rats.

Forty rats (200–250 g) were randomly divided in a blinded fashion into five groups (n=8).

Group 1 was sham operated and treated with vehicle (corn-oil, 10 mL/kg).

Groups 2, 3, 4, and 5 were rendered unilaterally cryptorchid and treated with vehicle (10 mL/kg), vitamin E solution (75 mg/kg), vitamin C solution (1.25 g/kg), and combination of vitamin E (75 mg/kg) and vitamin C (1.25 g/kg) solutions, respectively.

Germ cell count, superoxide dismutase (SOD), total protein (TP), and testicular weight (TW) were lower, but malondialdhyde (MDA) was higher in the cryptorchid rats than the sham-operated rats.

When administered separately, vitamins C and E increased germ cell count, SOD, TP, and TW but did not reduce MDA in the cryptorchid rats when compared to the vehicle-treated cryptorchid rats.

However, there was no significant difference in these parameters between vehicle-treated and combined vitamins C- and E-treated rats.

This suggests that vitamins E and C alleviate the germ cell loss and oxidative stress in cryptorchidism when administered separately but not when combined in rats.
